About Mark
Mark Stornetta is a hard-working, creative and results-driven professional. A Sonoma resident for more than 40 years, Mark’s connection to the community and land runs as deep and strong as the vines in this world-renowned wine-producing region.

An enthusiastic early riser, Mark starts his day with an eye on the details of each of his transactions, checking in with his clients and exhibiting the sincerity, warmth and respect that are the hallmarks of his business. Mark works primarily by referral, and his clients say that it’s the combination of his honest, grounded professionalism mixed with his knowledge of and experience in the local market that make his service so extraordinary.

Mark’s roots in Sonoma and Napa counties are intrinsically tied to the local wine industry business and culture. He started his career as a Farm Credit loan officer and branch manager before becoming general partner and CFO at Glen Ellen Winery. Later, he joined Gundlach Bundschu Winery as CFO. Now he brings his industry-based expertise in finance, sales and marketing to his clients at Compass Realtors.

Mark lives in Sonoma with his wife, Pat, where they enjoy sharing their favorite parts of wine country living—cooking and entertaining at home, dancing and hiking. They have four adult children and four grandchildren.


“Mark facilitated the purchase of a rental for us as part of a 1031 exchange. After listening to our needs he went out and identified several properties, ranging from commercial to single family residences before we made our final decision for purchase of a single family residence. He oversaw the entire process, solved problems along the way and closed in a timely period. We will use him again!”
- Jim & Marcia Mickelson - Jerry & Dons Yage, Pump & Well Kunde Estate Winery & Vineyards

“Throughout the long eleven month process, from negotiations through inspections and distillation of the preliminary title report for purchase of our vineyard and winery development property, Mark's attention was on us, always keeping our best interest in mind. I have complete trust and confidence in Mark.”
- Andrew Avellar - Carneros Vineyard Management

“For the many years Mark worked with us here at Gundlach Bundschu, Mark brought invaluable insight to our estate vineyard operation. He continues to be a valuable resource to this day, most recently assisting us in the analysis for purchase of land for vineyard development . A former vineyard lender and winery financial executive with extensive grape purchasing and estate vineyard management experience, Mark’s view of the vineyard land business is unique in my experience. His is truly a 360 degree perspective. Add that to his diligence, focus and, most importantly, his integrity, and one would be hard pressed to find better guide through the world of vineyard real estate.”
- Jeff Bundschu - Gundlach Bundschu Winery, fifth generation
