St. Helena, California

St. Helena is a small town at the heart of the Napa Valley, where in-town cottages share a market with vineyard estates, wineries and hillside land. Some agents here close a few very large sales, and others close many deals across price points. This ranking gives both equal weight by averaging each agent's position on RealTrends' volume list and its transaction sides list.

23 Agents Ranked
2 RealTrends Lists Combined
2026 List Year

RealTrends publishes two separate 2026 rankings of St. Helena agents: one by 2025 sales volume and one by transaction sides. On their own, each tells half the story. A volume ranking favors agents who sell a handful of large estates, and a sides ranking favors agents who close many smaller deals. This page averages the two so that an agent has to do well on both to rank near the top. All 23 agents on RealTrends' St. Helena volume list are included.

How This Ranking Is Built

Every number comes from RealTrends Verified's published 2026 St. Helena lists. The only step we add is the average:

💵

Position by sales volume

Each agent's rank on the 2026 RealTrends Verified list of St. Helena individual agents ranked by 2025 closed sales volume.

🤝

Position by transaction sides

Each agent's rank on the RealTrends St. Helena list ranked by transaction sides, the number of buyer and seller sides closed in 2025.

➗

Averaged with equal weight

The two positions are added and divided by two. The lowest average ranks first, and a tie in the average goes to the agent with higher sales volume.

For example, Erin Lail is #1 by volume and #2 by sides, an average of 1.5. Josh Dempsey is #4 by volume and #3 by sides, an average of 3.5. Ginger Martin is #3 by volume and #5 by sides, an average of 4.

RealTrends' St. Helena sides ranking lists six agents. For agents outside those six, the sides rank continues from #7 using the sides RealTrends reports for each agent on the volume list. The full calculation is shown in the table below the agent cards.

Hiring a Realtor in St. Helena, California: FAQs

Who are the top Realtors in St. Helena, CA in 2026?

Averaging each agent's position on the 2026 RealTrends Verified St. Helena lists by sales volume and by transaction sides, the top five are Erin Lail of Coldwell Banker Brokers of the Valley (average 1.5), Hillary Ryan of Sotheby's International Realty (average 3), Josh Dempsey of Vanguard Properties (average 3.5), Ginger Martin of Sotheby's International Realty (average 4) and Donna Hinds of Coldwell Banker Brokers of the Valley (average 6). The full order of all 23 agents is on this page.

How is this St. Helena ranking calculated?

We take each agent's rank on two RealTrends Verified 2026 lists for St. Helena individual agents, one ranked by 2025 sales volume and one ranked by transaction sides, and average the two with equal weight. The lowest average ranks first, and a tie goes to the agent with higher volume. RealTrends' sides list for St. Helena includes six agents; for everyone else, the sides rank continues from #7 using the sides RealTrends reports for them on the volume list.

Why combine sales volume and transaction sides?

Volume alone rewards agents who close a few very expensive sales, and sides alone rewards agents who close many smaller deals. In a market like St. Helena, where a single vineyard estate can outweigh a dozen in-town sales, averaging the two shows which agents are consistently active at every level.

Who is a good Realtor for vineyard and estate properties in St. Helena?

Several agents near the top of the combined ranking work the valley's estate market. Erin Lail of Coldwell Banker Brokers of the Valley is #1 by volume at $115.15M. Hillary Ryan of Sotheby's International Realty is #2 by volume at $113.74M. Josh Dempsey of Vanguard Properties ranks #3 on the combined list, #4 by volume at $80.81M and #3 by sides with 22, and works with vineyard, estate and in-town buyers and sellers. Ginger Martin of Sotheby's International Realty is #3 by volume at $106.95M.

Which St. Helena agents close the most transactions?

On RealTrends' 2026 St. Helena sides ranking, Mara Eichelmann of Sotheby's International Realty is #1 with 30 sides, followed by Erin Lail with 29, Josh Dempsey of Vanguard Properties with 22, Hillary Ryan with 21, Ginger Martin with 18 and Donna Hinds with 15.3.

What is the difference between sales volume and transaction sides?

Sales volume is the total dollar value of an agent's closed sales. Transaction sides count the deals: representing the buyer is one side, representing the seller is another. Fractional sides, such as 15.3, are how RealTrends credits transactions shared between agents.

How much does it cost to hire a Realtor in St. Helena?

Commission is negotiable and set by agreement between you and your agent. Since 2024's industry changes, buyers sign a written agreement with their agent that spells out compensation before touring homes, so discuss terms up front with any agent you interview.

What should I ask a St. Helena Realtor about buying vineyard land?

Ask about the property's water source and well reports, vineyard planting and lease agreements, Napa County agricultural preserve and winery permit rules, and comparable sales of similar acreage. An agent who has sold vineyard land recently can usually walk you through each of these.

How do I check a Realtor's reviews before hiring them?

Each card on this page links to that agent's public review profile on Zillow, Google or Yelp, where you can read client reviews at the source. Many luxury clients never post reviews, so pair reviews with the agent's closed sales.

Which St. Helena areas are most in demand?

Buyers often look at walkable homes near Main Street, the west side residential streets, hillside estates on Spring Mountain, rural parcels on Howell Mountain, and vineyard properties along the Silverado Trail and in Rutherford and Oakville.
