Our Team

Kevin Sass, Winemaker

It’s every winemakers dream to have 281-acres of sustainably farmed vineyard at your fingertips. The natural resources here at Halter Ranch are the best I have ever worked with.

A Southern California native, Winemaker Kevin Sass grew up in Agoura Hills graduating from California State University (Fresno) with a double major in Enology Wine Production and Agricultural Business.

Kevin has been making wine from the grapes at Halter Ranch Vineyard for 17 harvests. After 11 years at Justin Winery, which purchased grapes from the Halter Ranch Estate, he became Winemaker at Halter Ranch in 2011. A new state-of-the-art gravity flow winery and an estate wine-growing program has allowed Sass to showcase the 16 grape varieties planted on the 281-acre west side vineyard. Kevin lives in Templeton with his wife and sons.

Molly Lonborg, Associate Winemaker

Working at Halter Ranch is like a dream come true. The unique property, state-of-the-art winery, diverse vineyard, and amazing colleagues come together to form the perfect working environment. We are truly lucky to have all the resources we need to cultivate and create delicious, approachable, age-worthy wines, all while staying true to our common value of sustainability.

Molly joined the Halter Ranch team in June of 2011. Originally hired as the Lab Manager and Cellar Assistant, she was quickly promoted to Enologist, then Assistant Winemaker, and in January 2018, Molly was promoted to Associate Winemaker.

A graduate of Cal Poly, San Luis Obispo, Molly majored in Earth Sciences with a concentration in Wine and Viticulture. She has traveled extensively, and studied geology at the University of Otago in Dunedin, New Zealand. Molly worked her first harvest in the lab at Orcutt Road Cellars in San Luis Obispo and gained additional cellar experience working at Justin Winery with Halter Ranch Winemaker Kevin Sass. Molly lives on the Halter Ranch property with her husband Jordan Lonborg, who is the Viticulturalist at Tablas Creek Vineyard, and her dog Miles Davis. She enjoys gardening, hiking, traveling and live music.

Lucas Pope, Vineyard Manager

Our focus at Halter Ranch is on a 100-percent estate grape-growing program. We aim to improve the quality of the grapes coming off the ranch every year. Another is the continuation of the SIP (Sustainability In Practice) program to provide a legacy for future generations.

Lucas Pope joined Halter Ranch in 2012. Born in California, he was raised in Germany and Japan before returning to study viticulture at Cal Poly in San Luis Obispo. Lucas graduated in the first class of viticulture majors in 2006.

He has worked harvests in Coonawarra, South Australia, and South Africa, and owned a business managing vineyards in the Silicon Valley. Lucas managed the vineyards at Stolo Family Vineyards in Cambria for two years before moving to Halter Ranch. Lucas lives in Atascadero with his wife Nicole and two young children.
