Chris Larson (Chairman) is in his fifth year on the PZC. He brings 12 years of experience  as a citizen planner with Park City, 4 years on the Historic District Commission and  8 years as a Planning Commissioner (2 years as Chair). Both commissions were  decision-making bodies that dealt with many difficult problems due to growth and  changing socio-economic factors. During his tenure on the Park City Planning Commission, the city completely rewrote both the Comprehensive Master Plan and  the Land Management Code from the ground up. Chris started spending a considerable amount of time in Teton Valley in the mid-1990s, bought property and built a house. He and his wife Cathy moved here full time in 2005 and are actively involved in the community and in the daily activities of raising a young son. Chris earned a degree in Computer Science from the University of Utah and has a considerable amount of graduate level work under his belt. He owns a software development business that operates both locally and nationally. Chris has served on many boards over the past 25 years, including Teton Valley Hospital for 3+ years and Teton Valley Trails & Pathways for 6 years. He considers the current PZC as one of the best boards he has ever served on, from both a professional and policy perspective.

Erica Tremblay moved to Teton Valley with her husband and young son in 2001.  Her parents had moved to the valley in 1989 and she loved the valley every time she visited.  She and her husband were both in the tech industry and she retired after 25 years to help raise their son, while her husband continued to commute to consulting projects around the US.  In 2003 Erica joined Sotheby’s International Realty which began a 15 year career in Real Estate in Teton Valley.  Licensed in Idaho and Wyoming, Erica has hung up her shingles and will no longer be a licensed Associate Broker by the end of 2019.  Being in real estate during the boom and bust cycle in this mountain valley has instilled in her the desire to support better community planning and a long term view of all decisions regarding land and development. Erica is also an avid photographer and has great respect for our natural beauty and friendly community she lives in.  She has served the community in non-profit board capacities and feels that this valley has much to offer those that live here and newcomers who want to share in and protect the unique resources that we have.
