David Sinegal

Vintner and General Manager

Never one to sit still for long, David Sinegal’s work experience runs the gamut from Costco and Frito Lay to start-up and joint venture companies. David is a keen business strategist and visionary with a passion for marketing and innovation. And, of course, an unabashedly obsessive eye for detail.

Don’t let the casual vibe of the Estate fool you. David believes that in order to do anything well, one must be fully invested. That’s why he and his family now live on the property – so he can sleep at the “office.” Being at the Estate full-time inspires David every day to create a 360-degree guest experience that includes exceptional wine, delicious food, and a remarkable environment.

Ryan Knoth

Winemaker

With a lifelong passion for food and wine, Ryan realized – during an inspiring trip to wine country – that his dream was to have a career that allowed him to work with the land while creating a product that would be enjoyed by many.

Since joining the wine industry, Ryan has had the pleasure of working under the expert tutelage of David Abreu, Michel Rolland, and Fredrik Johansson at Staglin Family Vineyard and Jim Barbour & Philippe Melka at Gandona Winery.

He joined Sinegal Estate in its infancy and is excited to be applying his background of science and winemaking to crafting distinct
and elegant wines from this historic estate.

Trevor Antognini

Director of Operations

Growing up in Northern California in a multi-generational agriculture family, Trevor Antognini loves the outdoors.

Working with his father, a contractor, and his uncle, a landscape contractor, Trevor learned the skills to manage such highly regarded wine estates as Peter Michael Winery and the Sloan Estate in Rutherford.

At the Sinegal Estate, Trevor stewards the legacy of the property – managing the grounds, facilities and ensuring that every guest has an exceptional experience.
