Mark Stevens

BRE#: 00971195
Broker Associate

For those looking to buy or sell a winery in Sonoma, Napa or Mendocino County, realtor Mark Stevens is a powerful ally.  Stevens draws from over 30 years of expertise in the region as a country properties specialist, with training as a commercial broker and extensive counseling in real estate investment and development.

Stevens earned a Bachelor of Science in Molecular and Cellular Biology from the University of Washington. His passion for science propelled him to further study in viticulture in the mid-90s, which led to work with Sonoma Cutrer (Brown-Forman). Over the years, he has enjoyed working with many prominent figures in the wine industry, on the sides of both vineyard and winery sales and acquisitions.  He has assisted and advised in completing transactions with the following industry players: Kendall Jackson, Gallo, Paul Hobbs, Patz & Hall, Michel-Schlumberger (Jacques Schlumberger and The Adams Group), Carlisle Winery, and Richard and Saralee Kunde.

“I love this business,” he says. “It is exciting to participate in the process and counseling of property owners and businesses that make a real difference in the intelligent, rewarding use of our lands. [We’re] keeping our North Bay on a firm agricultural footing for generations to come through sustainable farm practices, and supporting a growing wine industry providing rewarding work for our residents.”
