Hadyn Schatz, new to the Board, is the Vineyard Manager at R&G Schatz Farms and a graduate of California Polytechnic University, San Luis Obispo with a degree in agricultural systems management. Schatz’s father Rodney served on the Board as Chair from 1997 to 1999. “I’m excited to continue to promote and assist in sustainable winegrowing in the Lodi wine region,” says Schatz.

“We are proud to have such a qualified and diverse Board of Directors guiding the efforts of the Commission and our larger agricultural community,” commented Lodi Winegrape Commission Executive Director Stuart Spencer. “I look forward to working with them to continue building on our great work supporting the region through the Commission’s primary initiatives of promotion, research, and education.”

Rolling off the Board of Directors are Aaron Shinn of Round Valley Ranches and Matt Lauchland of Lock L Ranches. Shinn ended his eight consecutive years (2015-2023) as the outgoing Board Chair and provided exceptional leadership not only to the Board but also to the LODI RULES Committee during this time. Lauchland has served on the Board of Directors for six consecutive years beginning in 2017. Both individuals continue to be active in the Commission’s initiatives and supportive of the ongoing efforts of the greater Lodi winegrowing community.

Thanks to these two outstanding men for their many contributions to the region, and to the entire 2023-2024 Lodi Winegrape Commission Board for their dedication, leadership and service!
