Keith used his Accounting degree while serving as Vice President of Overhead Construction for the telecommunication construction company, X-L Cable Corporation Inc. in Seattle, WA for many years. In 1996, Keith moved back to Vernal to work with his father, Lawrence B. Larsen, in his CPA practice while continuing to work for X-L Cable as the Controller until 2011.

When Keith isn’t working hard at the office, you can find him playing hard with his family and friends. Keith loves spending time with his wife, Sheri, and their four children. They enjoy being in the outdoors and, on any given weekend, you can find them cruising around a lake on their boat and wake surfing. When Keith isn’t on the boat, he wants to be camping, hunting, fishing, or traveling to see the world. But his main joy in life is being a husband, dad, and grandpa. Anything is better with family.
As a tax and accounting professional with MainStreet Tax & Accounting, Keith takes pride in serving our clients.
