Company Background

Josh Dempsey was raised in Connecticut and moved west to attend Santa Clara University, where he earned a BS in Economics in 2000. He began his real estate career that year in commercial real estate brokerage in Palo Alto, in Silicon Valley. After two years, a developer client hired him to help develop, build and sell 160 condominiums at The Boulders in Truckee, California. He founded Boulders Realty to act as Broker of Record for the project.

Josh married Erin Dempsey in 2007. That year the couple were hired by the owners of Calistoga Ranch, an Auberge Resorts property developed by Olympus Real Estate Partners, as Director of Real Estate and Marketing Director. Over six years (2007 to 2013) they sold six residences and 140 fractional memberships, completing the real estate offering. The final fractional interests closed on February 27, 2013.

He then joined Coldwell Banker in St. Helena (Coldwell Banker Brokers of the Valley) as a Broker Associate, representing buyers and sellers of residential, vineyard and winery properties. He received Coldwell Banker's International President's Premier Award in 2013, 2014 and 2015. During this period Four Seasons Napa Valley retained him as exclusive listing agent for all 20 Four Seasons branded residences in Calistoga, priced from $3.5 million. The residences sold out at record pricing with about $90 million in sales.

In February 2021 Vanguard Properties appointed him Regional Director, Napa Valley. He worked with Vanguard ownership to open the company's 16th Northern California office and its first in Napa Valley, in St. Helena. After an 18-month renovation of the historic building at 1345 Railroad Avenue (the former Terra Restaurant), the office opened there on September 1, 2022. His career sales total more than $950 million as of September 2026. He closed more than $165 million in the two years ending 2025 and more than $80 million year to date in 2026. He and Erin live in St. Helena, where they have raised their two children.
