Lee Wilson began his insurance career in 2008, helping individuals and families with home and auto coverage. In 2011, he found his true calling in Medicare and retirement planning. Since then, he’s dedicated himself to guiding seniors through the complexities of Medicare with clarity and care.

In 2016, Lee founded Teton Medicare with a vision to provide personalized, independent insurance solutions. What started as a one-man agency quickly grew, adding a team of trusted agents who share his commitment to service and integrity.

In 2023, Lee partnered with Casey Peterson and Generations Insurance to expand their impact and form the new Teton Medicare. Together, their combined teams are helping more people across the region access the right Medicare coverage and retirement protection.

Lee is married to Emilie Wilson, and together they have four children: Kate, Claire, Allie, and Max. Outside of work, Lee enjoys spending time with his family, traveling, snorkeling, staying fit, and playing golf. He loves watching his kids compete, and he enjoys serving in his community and church.

Casey started his insurance career in January 2009. He began as an independent insurance agent helping people with their Medicare and life insurance needs throughout Washington state. After 3 years in Washington, Casey and his family moved to Idaho Falls, Idaho where he became an independent insurance broker. At that same time, Casey formed the Generations Insurance Agency. With his new company, he was able to branch out to more states, offering more products, from many more insurance companies.

In early 2023, Casey merged his business with Lee Wilson, and Generations Insurance became Teton Medicare. Teton Medicare currently helps thousands of clients in 9 states with their Medicare and retirement insurance needs.

Casey had been married to his wondeful life Alicia since January 2000. They have 4 amazing children; Sean, Chase, William, and Grace. Casey enjoys boating in the summer, traveling at any time, the snow, the mountains, and cooking a really good meal for his family and friends.
