Silas Rossow


Silas received his college education at Cal Poly, San Luis Obispo and was blessed to grow up around agriculture his whole life. Driving tractors, irrigating fields, and figuring out how crops grow was a valuable education. Silas began his career at CAS in the fall of 2008 as a Customer Account Manager. In 2014, Silas began managing the day-to-day operations at CAS and is now a business partner with founder Monte Bottens.


His drive to seek out the very best practices for California farmers comes from his love of agriculture and technology. He’s excited about the opportunity to work with new growers and help them find solutions to the problems they face. 


Perhaps the most interesting thing about Silas is his enthusiasm for the perfect practical joke. He enjoys a good laugh and having fun. His wife, Julie, and three children make for a captive audience and are his biggest fans.


Matthew Rossow

VP of Operations

Matthew’s career in agriculture has taken him all over the world and spanned decades of adventures. His education and experience give him the expertise of being able to communicate complex technologies to a wide range of people, taking theoretical ideas and turning them into practical everyday tools to help growers be more efficient.


His role at CAS is to oversee the daily operations of the company's equipment and facilities. Some days he is "Mr. Fix-it" with dirty coveralls on, and some days he is at his computer designing and engineering solutions to help our growers farm more efficiently, enabled by our services. He is the company's equipment-nut, gear-head, tech-nerd, head fabricator, shop-teacher, and oh- loves to grow things too!


Matthew recalls a weekend “vacation” in the Middle East as one of the most interesting experiences of his life. He loves experiencing different cultures and seeing different scenery, especially in rural agricultural areas. He enjoys sharing those experiences with his wife Ann. They live on a farm in Dos Palos, CA.
