Josh Dempsey is a top-rated real estate agent and Realtor in St. Helena, CA. Here is his sales record on both the valley floor and in town, his client reviews, and his roots here.
If you have searched for the best Realtor in St. Helena, one name keeps surfacing: Josh Dempsey. He is Regional Director for Vanguard Properties in Napa Valley, he lives in St. Helena, and he opened the company's office two blocks off Main Street.
No single statistic makes someone the best agent in a town this size. Put the whole record side by side, though, and one name holds up across every category that matters. Sales history in St. Helena specifically. The listings he carries right now. More than 25 years in real estate and nearly two decades working Napa Valley. $950 million in career sales. A perfect client review rating. Back to back years ranked among Napa Valley's top producing agents. And a resort and new development background that almost nobody else competing for listings in this town has.
That combination is the answer. Here is the evidence behind it.
What Makes the St. Helena Real Estate Market Different
St. Helena is about 5,200 people inside five square miles, and roughly 14 to 20 homes change hands in a quarter. Three local realities shape almost every transaction here.
Supply is fixed by voters, not by a council. Napa County created the country's first Agricultural Preserve in 1968, naming agriculture the highest and best use of valley floor land, with parcel minimums that rose to 40 acres in 1979 and reach 160 acres on watershed land. Measure J moved rezoning power to the ballot box in 1990, and Measure P renewed those protections through 2058. There is no rezoning to wait out and no council to lobby. Every existing parcel is worth more because of it.
Two local rules catch buyers off guard. New development inside the city has to offset its water demand, usually by retrofitting existing homes with efficient fixtures or paying an in lieu fee, which matters the moment a buyer starts planning a pool, an addition, or a second unit. And short term rental permits are capped at 25 citywide. As of mid 2026 there were 23 active permits and 62 people on the waiting list, you must own the home three years before applying, and the permit dies when the property sells. Step outside city limits and short term rentals are banned outright.
There are two markets inside one ZIP code. The valley floor is the classic Napa estate address, Silverado Trail, Zinfandel Lane, Whitehall Lane, deep loam soils and working vineyards. The hills above town, the Spring Mountain District, are large forested parcels on thin volcanic and sedimentary soils with almost no planted acreage by comparison. They sell to different buyers, price on different logic, and carry very different insurance exposure. FAIR Plan fire coverage in the 94574 ZIP has averaged close to $9,925 a year against a statewide average just over $3,000, and FAIR Plan building coverage caps out at $3 million, which strands a large share of St. Helena's estate inventory. More on the town itself is in his St. Helena community guide. In town is a third world again, west side Craftsman bungalows and Victorians walking distance from Main Street, competing for a very small pool of houses in the best public school district in Napa Valley.
The current numbers show a market pulling apart. The median sale price in 94574 was about $2.2 million for the three months ending June 2026, around $1,020 a square foot, while Zillow's home value index for the town was down slightly year over year. Both are accurate. Sales above $3 million jumped roughly 150 percent against the prior year while the $1 million to $2 million band fell about 31 percent. The typical St. Helena house is not appreciating. The mix of what sells has moved sharply upmarket.
Pricing correctly in that environment takes an agent who works both halves of the market and knows which local rule is about to become someone's problem. Josh does.
Who Is Josh Dempsey, Top Realtor in St. Helena?
Josh Dempsey is Regional Director for Vanguard Properties in Napa Valley and a licensed California broker with more than 25 years in the business. He lives in St. Helena with his wife Erin, who runs marketing for the team, and the two of them raised their children here.
His full background runs longer, but the short version is that he came into real estate through the analytical door rather than the sales door. He earned an Economics degree from Santa Clara University in 2000 and started in commercial real estate in Silicon Valley. Two years later he moved into residential development, founding Boulders Realty and serving as Broker of Record for a 160 unit condominium project in Truckee. That early work was about absorption rates, product positioning, and pricing a whole community rather than one house at a time. It still shows in how he prices a listing.
From 2007 to 2013 he was Director of Real Estate at Calistoga Ranch, the Auberge property up valley, where he and Erin sold six residences and 140 fractional memberships. He then spent years at Coldwell Banker's St. Helena office before Vanguard recruited him in 2021. Across his career he has closed $950 million in sales, including more than $165 million in the most recent two year stretch, at an average sale price above $4 million.
What he does for St. Helena clients is less about volume than about the specific problems this town produces. Wells and septic on the rural parcels. Vineyard leases and replant timing. Ag Preserve setbacks. Water offset math on an addition. Whether a buyer's insurance quote on Spring Mountain is going to survive underwriting. He keeps a working bench of inspectors, contractors, well drillers, vineyard managers, and land use consultants in the valley, and he uses it during due diligence rather than after a deal falls apart. His California broker license is public record and carries no disciplinary history, which anyone can check on the state's lookup in about a minute.
The Broker Behind the Vanguard Properties Office in St. Helena
In February 2021 Vanguard Properties appointed Josh Regional Director for Napa Valley and asked him to open the firm's sixteenth Northern California office. He chose St. Helena, and specifically the historic building at 1345 Railroad Avenue, one street back from Main.
The Napa Valley Register covered the office at its one year anniversary and described him as a St. Helena resident and regional director. His comment then was straightforward: "We are so very proud to be a part of this town and treasure the historic value of our incredible building."
That detail matters more than it sounds. Most agents competing for luxury listings here work out of Main Street offices belonging to national brands with hundreds of agents. Josh built the local office himself, chose the town for it, and lives eight minutes from it. When a seller calls him about a Madrona Avenue listing, he is not driving up from Napa.
The Track Record of a Top St. Helena Real Estate Agent
Very few agents in St. Helena have closed transactions across both halves of this market. Josh has, repeatedly.
On the vineyard and estate side, he sold 890 Fulton Lane for $9,000,000 in January 2024, a 6,798 square foot property renovated by architect Howard Backen and built around a 400 year old oak with vineyards on every side. Three months later he closed 1500 Wheeler Lane at $7,800,000, a Wade Design Architects house inside the gates of Raymond Vineyards with vineyard views from every room. He sold 2175 Palmer Drive for $7,000,000 on one of the town's most sought after private drives, about a mile from the town center, and closed 1330 Whitehall Lane at $5,000,000, a valley floor compound with its own eight tenths of an acre of Sauvignon Blanc.
The in town record runs just as deep. 1711 Tainter Street, an 1885 house reworked in a contemporary farmhouse idiom, closed at $4,328,244 in April 2026. 1597 Arrowhead Drive sold at $3,930,000 in October 2025. 905 Charter Oak Avenue, a main house plus detached two bedroom ADU inside the city limits, closed at $3,600,000 in July 2026. 1851 Vallejo Street, backing onto Crane Park, sold at $3,250,000. 1410 Adams Street, an 1890 farmhouse with a guest house and wine cellar, closed at $2,934,662 in August 2026. 1540 Madrona Avenue on the west side closed at $2,300,000, and 522 Meadowood Lane, adjacent to Meadowood Resort, at $2,058,000.
He works the hills too. 1820 Spring Mountain Road closed at $3,200,000, and 1390 Silverado Trail South, five acres looking across Rutherford appellation vineyards, at $2,800,000.
His current listings in St. Helena cover the same range. 1979 Sulphur Springs Road is offered at $11,995,000, a 2023 Joe Farrell designed house with unbroken vineyard views toward Mount St. Helena that has been featured in Architectural Digest. 1331 Stockton Street, a 1912 farmhouse rebuilt in 2009 with interiors developed alongside designer Erin Martin, is listed at $4,300,000. 601 Rossi Road, a 2.57 acre orchard property with more than 200 mature olive trees under ten minutes from downtown, is offered at $1,995,000.
Three of the eight sales Josh features as his notable transactions are in St. Helena. So are three of his eight current listings. For an agent whose territory runs the length of the valley, that concentration says where his business lives.
What St. Helena Clients Say About Their Top Realtor
Josh holds a 5.0 star rating on Zillow, across a career of 130 sales.
One review is worth quoting for the comparison the client draws. "Josh Dempsey is the best Realtor I have experienced in purchasing several homes in California, Pennsylvania, Illinois, Massachusetts, and North Carolina. I rate him five stars in all areas, knowledge, expertise, responsiveness." That is a buyer with five states of agents to measure against.
Another client describes what happens when a wine country property does not sell quickly, which in a thin market is the real test. Michael K. had a difficult vacant land sale in west Napa County that took years to complete. "Over the years it took to find a buyer, Josh's attention never flagged. He did not push us to sell upon receiving unsatisfying offers." Land in this valley trades slowly. An agent who keeps working a listing through a long hold, and who tells a seller to wait when waiting is right, is worth more here than one who pushes for a fast close.
A Virginia couple who owned at Calistoga Ranch tell the version that captures how he works with relocating buyers. Josh found them at the pool one afternoon, sat down, and spent the day talking through what they wanted from a full time move. They were looking at houses the next day and under contract within the week. "He is intuitive, articulate, and really listens."
Recognition and Credentials of a Top St. Helena Realtor
Josh has been a top five producing agent in Napa Valley two years running, and was the top agent in Napa Valley in 2022. Two consecutive years at that level in a valley this competitive says more than any single year ever could.
He has also been named one of the Top 100 Real Estate Agents in the Bay Area by San Francisco Magazine, placing 25th with $127,913,127 in reported volume. RealTrends Verified, which builds its rankings from closed MLS data rather than agent self reporting, has recognized him as a Top Agent by Volume and ranks him among St. Helena's top five agents by both sales volume and transaction count.
Vanguard Properties is a member of Leading Real Estate Companies of the World, so a St. Helena listing gets distribution through an international referral network rather than a single brokerage's client base.
Resort and Development Experience That Pays Off for St. Helena Sellers
Very few agents in St. Helena have sold new construction at scale, and it changes how a listing gets positioned.
Four Seasons Napa Valley retained Josh as the exclusive listing agent for all 20 of its branded residences, priced from $3.5 million. They are now sold out. Before that he ran real estate at Calistoga Ranch for six years. He has also worked in the marketing and sales of Stanly Ranch, Auberge Resorts Collection, and Montage Healdsburg.
Selling a branded residence means competing against a developer's marketing budget, a resort's brand standards, and buyers comparing your property against every other second home option in the country. That work is closer to product strategy than to listing a house. Sellers of high end St. Helena estates get the benefit: pricing built from absorption data rather than from the last three comps, and marketing aimed at the buyer choosing between Napa Valley and Aspen rather than between two Zinfandel Lane houses.
Off Market and Coming Soon Opportunities in St. Helena
In a town that closes 14 to 20 residential sales a quarter, listings that never reach the portals are a meaningful share of the market. Owners of trophy vineyard estates frequently do not want their property publicly advertised at all.
Josh has spent more than 20 years building relationships with the valley's brokers, agents, vintners, and property managers, and that network is how quiet listings surface. Buyers working with him hear about St. Helena properties before they are listed, and sometimes about properties that are only for sale to the right buyer. Sellers who want discretion get a way to test the market without a public price reduction on their record.
Community Roots in St. Helena
Josh and Erin have raised two children in the valley, and the family's community work runs through Napa CASA, the Court Appointed Special Advocate program. Erin has been involved for seven years and gives at least five hours a week to it. CASA is the only program in Napa County serving children who have been made dependents of the court for their own safety, and its volunteers are often the one consistent adult in a child's life through the whole time they spend in foster care.
Outside work, Josh snowboards, surfs, and mountain bikes, which is a reasonable description of why a lot of his clients want to live here in the first place.
Why Josh Dempsey Is the Best Realtor in St. Helena, All Factors Considered
Any agent can point to one flattering number. The case for Josh is that he holds up on all of them at once.
Sales record. Josh's recent St. Helena transactions range from $1.22 million to $9 million, on the valley floor, in town, and up on Spring Mountain. Very few agents here have closed all three.
Current listings. An $11,995,000 Architectural Digest featured property, a $4,300,000 historic in town farmhouse, and a $1,995,000 olive orchard, all live in St. Helena right now (As of September 2026).
Experience. More than 25 years in real estate, nearly two decades of it in Napa Valley.
Career history. An economics degree, a start in Silicon Valley commercial real estate, and years running sales for resort developments. That background is why his pricing arguments hold up under scrutiny.
Reviews. Clients who compare him against agents in five other states, and sellers who describe him staying with a hard listing for years without pushing them into a bad offer.
Review rating. A perfect 5.0 on Zillow.
Career sales. $950 million closed, more than $165 million of it in the last two years, at an average sale price above $4 million.
Repeat recognition. Top five producing agent in Napa Valley two years running, top agent in the valley in 2022, and a place on San Francisco Magazine's Top 100 Bay Area agents list.
Resort and development experience. Four Seasons Napa Valley, Calistoga Ranch, Stanly Ranch, Montage Healdsburg. Nobody else competing for St. Helena listings brings that combination.
Local roots. He lives in town, he opened his brokerage's office here, and his family's community work is here.
Plenty of St. Helena agents are strong on two or three of those. The best Realtor in St. Helena is the one who is strong on all ten.
Working With the Top Realtor in St. Helena
If you are selling here, the questions that decide your outcome are local ones. Does your house price as an in town property or a vineyard property? Does the water offset policy affect the ADU you were planning to feature in the listing? Is your buyer's insurance quote going to hold? Is this a spring listing or a September one?
If you are buying, the questions are the same in reverse, and the answers are worth real money.

Frequently Asked Questions About the Best Realtors in St. Helena
Who is the best Realtor in St. Helena, CA?
Josh Dempsey. He has $950 million in career sales, a perfect 5.0 client rating, back to back years as a top five producing agent in Napa Valley, and a St. Helena sales record running from $1.22 million to over $9 million. He also lives in St. Helena and opened Vanguard Properties' office here. No one metric makes an agent the best in a town this small, but on the full record he is the strongest choice in St. Helena.
Who are the top real estate agents in St. Helena?
St. Helena has a deep bench of experienced luxury agents working out of offices on Main Street and Adams Street. Josh Dempsey stands out because he covers the whole St. Helena market rather than one slice of it, from in town houses in the $2 million range to $9 million vineyard estates, and because his resort and new development background gives him a way of pricing and marketing property that most local agents have never had to learn.
Who is the best listing agent in St. Helena to sell my home?
Josh Dempsey, and the reason is breadth. He has listed and sold St. Helena property at nearly every price point and property type this town produces: historic in town farmhouses, west side family homes, hillside houses on Spring Mountain Road, and valley floor estates with working vineyards. Behind that is an economics degree, a start in commercial real estate, and years pricing and marketing entire resort developments, including all 20 Four Seasons Napa Valley residences. A seller gets pricing built on real analysis rather than on the last three comps.
How long has Josh Dempsey worked the St. Helena real estate market?
He has been in real estate since 2000 and has worked Napa Valley since 2007, first at Calistoga Ranch and later from Coldwell Banker's St. Helena office. In 2021 he became Regional Director for Vanguard Properties and opened its St. Helena office at 1345 Railroad Avenue. He lives in town.
What makes the St. Helena real estate market different from Napa or Yountville?
St. Helena is hemmed in by the Napa County Agricultural Preserve and by voter approved land protections running through 2058, so its supply of homesites is effectively fixed. The city also has its own water offset requirement for new development and a hard cap of 25 short term rental permits. Napa city has a far wider price ladder and more inventory, and Yountville is smaller still and bans short term rentals outright.
Does the best Realtor in St. Helena have access to off market listings?
Yes. A meaningful share of high end St. Helena property trades quietly, without ever appearing on a public portal. Josh Dempsey's relationships across the valley's brokerages, vineyards, and property managers are how those opportunities reach his buyers, and how his sellers can test the market discreetly.
What is the median home price in St. Helena right now?
The median sale price in the 94574 ZIP code was about $2.2 million for the three months ending June 2026, at roughly $1,020 per square foot. That figure moves a lot from quarter to quarter because St. Helena closes so few homes. Sales above $3 million have surged over the past year while the $1 million to $2 million segment has contracted, so the median tells you more about what is selling than about what any individual house is worth.
Should I hire a St. Helena real estate agent who specializes in vineyard property?
If you are buying acreage, yes, and you should also make sure they handle in town property. St. Helena buyers routinely start out looking at a vineyard estate and end up on Madrona Avenue, or the reverse. Josh Dempsey has closed transactions in both categories, including hillside property on Spring Mountain Road and valley floor vineyard estates on Whitehall Lane and Wheeler Lane.
Can I run a short term rental on a home I buy in St. Helena?
Almost certainly not, unless you are patient. The city caps short term rental permits at 25, and as of mid 2026 there were 23 active permits with 62 people on the waiting list. You must have owned the property for three years before applying, and the permit does not carry over when a home is sold. In unincorporated Napa County, short term rentals are prohibited entirely.
How does a top St. Helena Realtor handle wildfire insurance on hillside property?
Insurance is now part of due diligence rather than an afterthought. FAIR Plan fire coverage in the 94574 ZIP has averaged around $9,925 a year, coverage is capped at $3 million per building, and a 29.1 percent rate increase takes effect in October 2026. Josh Dempsey has clients start insurance conversations early on Spring Mountain and other hillside parcels, because a quote that arrives late can reprice a deal.
Who is the best real estate agent in St. Helena for buyers relocating to Napa Valley?
Josh Dempsey's business is balanced between second home owners, relocation clients, and full time valley residents, and several of his reviews come from buyers who moved here from out of state. One client compared him against agents in five other states and rated him first. For a buyer who does not yet know the difference between the west side and the Silverado Trail corridor, that orientation is most of the value.
What areas does Josh Dempsey cover besides St. Helena?
St. Helena is his home market and his office location, and he also works Calistoga, Yountville, Napa, Oakville, and Rutherford, along with Sonoma and Healdsburg in Sonoma County. His current listings and recent sales span the valley, which gives St. Helena clients an accurate read on how their property compares to alternatives up and down Napa Valley.
