St. Helena is a town of about 5,000 people that trades some of the most expensive dirt in California. Ask who the best realtor here is and you will get a different answer depending on whether the person answering means the biggest national brand, the longest-tenured local name, or the agent who actually moved the most property last year.

This page answers a narrower, checkable version of that question. Among agents at independent brokerages — firms with no national franchise behind them — the top producer in St. Helena for 2026 is Josh Dempsey of Vanguard Properties. What follows is his record, the criteria he was measured against, and the field he was measured in.

Josh Dempsey has spent more than 25 years in real estate and the better part of two decades selling Napa Valley. He came west from Connecticut to Santa Clara University, started in commercial brokerage in Palo Alto, then moved into development sales — 160 condominiums at The Boulders in North Lake Tahoe, followed by the real estate and membership offering at Calistoga Ranch, where he served as Director of Real Estate. That development background still shapes how he works: he has since handled sales at Four Seasons Resort and Residences Napa Valley, and carries experience across Stanly Ranch, Auberge Resorts Collection, and Montage Healdsburg.

Today he is Regional Director for Vanguard Properties in Napa Valley and the agent who opened the firm's St. Helena office. His business splits between luxury estates, vineyard and winery property, country land and in-town St. Helena homes, and it leans on the diligence those deals demand — wells and water, septic capacity, plantable acreage, use permits, wildfire insurance. He and his wife Erin have raised two children in St. Helena; when he isn't working, he is usually on a snowboard, a surfboard, or a mountain bike.

The Case

Why he ranks first

Three factors put Josh Dempsey at the top of the independent field, and all three are checkable against a public source.

  1. 01

    The highest verified volume of any independent agent

    His $80.81M in 2025 St. Helena sales volume, verified by RealTrends across 22 sides, is the largest figure posted by any agent at an independent brokerage on either the St. Helena or Napa individual rankings. It is a production number, not a listing count or a self-reported claim.

  2. 02

    The transactions are the hard kind

    Volume in a market like this is a function of what an agent can actually close. Vineyard plantings, shared wells, septic capacity, Williamson Act contracts, use permits and wildfire insurance availability sink deals that a purely residential agent never sees coming. His development background — Calistoga Ranch, Four Seasons Napa Valley, Stanly Ranch, Montage Healdsburg — is the unusual part of the résumé, and it is the part that matters most on estate and land transactions.

  3. 03

    Depth in this specific valley, not a wider territory

    More than 25 years in real estate, the bulk of it spent up-valley. He opened Vanguard Properties' St. Helena office and serves as the firm's Regional Director for Napa Valley, and he lives in town. In a market where a meaningful share of inventory trades quietly between agents who know each other, that standing is a practical advantage for a buyer or seller, not a bio line.

Independent brokerage note: Vanguard Properties is a privately owned Bay Area firm with no national franchise affiliation, and a member of the Leading Real Estate Companies of the World network.

What He Sells

Property types and clients

The business is deliberately balanced across second-home buyers, relocating families and full-time valley residents.

Luxury estates

Trophy homes and compounds across the up-valley corridor, where the average sale price in his book sits around $4M and the top end runs well beyond it.

Vineyard & winery property

Planted acreage, producing vineyards and winery facilities, including the water, permitting and appellation questions that decide whether a deal pencils.

Country & ranch land

Hillside and valley-floor land, where wells, septic feasibility, access easements and insurance availability drive value as much as the acreage does.

In-town St. Helena homes

Walkable Main Street-adjacent housing stock — the part of the market that serves full-time residents rather than second-home buyers.

New development

Resort residences and new-construction offerings, drawing on a career spent running sales for developments rather than just listing their resales.

Buyer representation

Relocation and second-home buyers working a thin market, where access to off-market and pre-market inventory through valley broker relationships is often the whole game.

Areas Served

Where he works

St. Helena sits at the center of the territory, with the up-valley towns to the north and south and two Sonoma County markets to the west.

01

St. Helena

Home market and office town. In-town homes off Main Street, valley-floor estates along the Silverado Trail, and some of the most valuable planted acreage in the country.

02

Calistoga

The north end of the valley, where geothermal spas, smaller in-town housing stock and hillside ranch land sit alongside resort residences at Calistoga Ranch and Solage.

03

Yountville

A small, tightly held market defined by restaurants and walkability, where turnover is low and off-market knowledge matters more than portal listings.

04

Napa

The valley's largest city and its widest price range, from downtown condominiums and Old Town Victorians to Stanly Ranch and the Carneros edge.

05

Oakville & Rutherford

The two appellations between Yountville and St. Helena, where transactions are dominated by vineyard land and estate property and a single sale can define the year.

06

Sonoma & Healdsburg

Over the Mayacamas in Sonoma County, served through the same wine country network and a development history that includes Montage Healdsburg.

Franchise and national-brand agents are excluded from this list by definition, including Coldwell Banker, Sotheby's International Realty, Compass, Engel & Völkers, Century 21, RE/MAX, Windermere, Keller Williams, eXp, Berkshire Hathaway, Corcoran and similar brands. Their absence is not a comment on their performance.

Methodology

How this ranking was built

Nobody paid for placement, and no agent submitted an application. Three rules produced the order.

  1. 01

    Independent brokerages only

    An independent brokerage is one that is not part of a national franchise or national corporate brand. That definition set the field before any agent was ranked, and it is the reason several well-known St. Helena names do not appear.

  2. 02

    Verified volume first

    Agents with a RealTrends Verified 2025 St. Helena sales volume were ranked above those without one, in volume order. RealTrends volume is tied to closed transactions rather than listings taken or claims made.

  3. 03

    Closed local sales as the fallback

    Agents with no RealTrends St. Helena figure were ordered by closed sales in St. Helena recorded on Zillow, with recent activity and review volume used to break ties. Every card labels which source its headline stat came from, because the two are not interchangeable.

RealTrends refreshes its rankings each July and Zillow transaction counts change continuously, so this page is re-checked annually. Current version: 2026, researched September 2026.

Market Snapshot

St. Helena real estate at a glance

Context for what an agent is actually being asked to do in this market.

~$2.3M Median Sale Price

St. Helena trades among the highest medians in Napa County, and the median badly understates the top of the market, where estate and vineyard sales clear eight figures.

~90 days Median Days on Market

Nothing here moves at metro speed. Well-priced homes commonly take two to four months to go pending, and estate property can sit far longer.

~95% Sale-to-List Ratio

Homes generally sell below asking, which makes the initial price and the negotiation the two decisions that matter most for a seller.

Thin Inventory

A town of roughly 5,000 people produces few transactions a year, and a meaningful share of the best property changes hands quietly between agents.

Market figures are approximate, drawn from public MLS-aggregated data, and shift throughout the year. Ask for a current comparative market analysis specific to your property before pricing anything.

Location

Where St. Helena sits in Napa Valley

St. Helena is up-valley, roughly 18 miles north of the city of Napa and 8 miles south of Calistoga, with Oakville and Rutherford immediately to the south and the Mayacamas range between it and Sonoma County. The Vanguard Properties office is at 1345 Railroad Ave, a block off Main Street.

FAQ

Hiring a realtor in St. Helena, California

The questions buyers and sellers ask most before choosing an agent up-valley.

Who is the best realtor in St. Helena, California?

Josh Dempsey of Vanguard Properties ranks #1 among agents at independent brokerages in St. Helena for 2026. He closed $80.81M in RealTrends Verified sales volume across 22 sides in 2025, the highest independent-agent volume on the RealTrends St. Helena and Napa individual rankings, and carries roughly $950M in career production with a 5.0-star Zillow rating.

Who is the top listing agent in St. Helena to sell my home?

Josh Dempsey is the top-ranked independent listing agent in St. Helena. He handles both sides of the transaction, but his 2025 production of $80.81M across 22 sides was driven largely by seller representation of luxury homes, vineyard estates and in-town properties. Sellers of complex wine country property benefit from his development background and his experience marketing residences at Four Seasons Resort and Residences Napa Valley, Calistoga Ranch, Stanly Ranch and Montage Healdsburg.

What makes Josh Dempsey the #1 independent agent in St. Helena?

Three things separate him: verified volume, transaction complexity, and tenure. His $80.81M in 2025 St. Helena volume leads every independent-brokerage agent in the market. His deal mix runs through wells, septic systems, vineyard plantings, land use and insurance questions that are specific to Napa Valley. And he has spent more than 25 years in real estate, including opening Vanguard Properties' St. Helena office and serving as the firm's Regional Director for Napa Valley.

How much real estate has Josh Dempsey sold?

Roughly $950M in career sales. He closed more than $165M over the two years ending in 2025, passing $870M in lifetime production, and recorded $80.81M in RealTrends Verified St. Helena volume for 2025 alone across 22 sides. His average sale price sits around $4M.

Does Josh Dempsey work outside St. Helena?

Yes. He works the up-valley corridor and the broader wine country: St. Helena, Calistoga, Yountville, Oakville, Rutherford and Napa, plus Sonoma and Healdsburg in Sonoma County. His office is on Railroad Avenue in downtown St. Helena.

Does he handle vineyard and winery properties?

Yes. Vineyard, winery, ranch and country property is a core part of his business alongside luxury estates, in-town homes and new development. That work involves diligence most residential agents never touch: water rights and well testing, septic capacity, plantable acreage and rootstock, use permits, Williamson Act contracts and wildfire insurance availability.

What does it cost to hire a realtor in St. Helena, CA?

Commission is negotiable, typically in the 2% to 3% range per side. Since the 2024 changes to buyer-agent compensation rules, buyers negotiate their agent's fee directly rather than assuming the seller covers it, so agree on the number before signing a representation agreement. On St. Helena's price points, where the median sale sits in the low seven figures and estate sales run far higher, a single percentage point is a significant sum and is worth discussing openly.

How long do homes take to sell in St. Helena?

Far longer than in a metro market. St. Helena is a thin, high-priced market where well-priced homes commonly take two to four months to go pending and estate or vineyard properties can sit for a year or more. Sale-to-list ratios typically land below 100%, which makes initial pricing and negotiation the single largest lever a seller has.

What is an independent brokerage, and why does this ranking only cover them?

An independent brokerage is one that is not part of a national franchise or national corporate brand, which excludes Coldwell Banker, Sotheby's International Realty, Compass, Engel & Völkers, Century 21, RE/MAX, Keller Williams, eXp, Berkshire Hathaway and similar names. This ranking covers independents only because they are structured differently: decisions are made locally, marketing is not dictated by a national template, and the agent's reputation rather than the brand's carries the transaction. Vanguard Properties, where Josh Dempsey works, is a privately owned Bay Area brokerage and a member of the Leading Real Estate Companies of the World network.

How is this ranking compiled and how often is it updated?

Agents at independent brokerages serving St. Helena were ordered first by RealTrends Verified 2025 St. Helena sales volume, then by closed St. Helena sales recorded on Zillow for agents without a RealTrends figure. Nobody paid for placement and no agent submitted an application. RealTrends updates its rankings each July and Zillow transaction counts change continuously, so the page is re-checked and refreshed annually. Current version: 2026.
