Meet the Team

Kent H. Whitmer, Managing Member

Kent is the founding member of The Whitmer Law Firm, LLC. He graduated from the University of Colorado in 1989 with a law degree and an MBA, and is licensed to practice law in Colorado, Wyoming, and Montana. From 1991 to 2015, in addition to being a solo practitioner, Kent owned and managed Grand County Title and Escrow Company, Inc.

Kent’s prior connection to the title and escrow business provided him with extensive experience in real estate matters. For over 35 years, he has represented buyers and sellers, developers, ranchers and other land owners in connection with their transactional, development or litigation real estate needs.

In 2017, Kent assumed retiring attorney Stan Cazier’s Grand County water practice. With that acquisition, Kent’s practice has expanded to include all types of water matters, including representing clients in Water Court, and general counsel representation of water and sanitation districts, and water conservancy districts.

In 2021, Kent assumed retiring attorney Rod McGowan’s practice. With that transition, Kent assumed and was appointed Town Attorney for the Town of Fraser.

Experience matters and Kent’s extensive and diverse background provides clients with sound direction and guidance.

Kent is married to Christina, the former Grand County Treasurer and Public Trustee. Kent and Christina live on a working—but not quite self-supporting—ranch located north of Kremmling, Colorado. When not practicing law, Kent is usually working on the ranch, enjoying family and friends, hunting or skiing.

As we all know, you can't beat Colorado, so Cooper and his wife Margeaux returned home after three years in Michigan and have been loving every minute of their mountain lifestyle! Their dog Odin runs the show, so they often spend their time walking and playing with him, hitting the slopes, or listening to live music around the town.
