Our story:

Generations Insurance founder and lead agent is Casey D. Peterson. In 2008, while living in the Seattle, Washington area Casey started his insurance career. He began as an independent career agent with a national insurance company covering plans in all of Washington State. From the beginning Casey enjoyed working with clients both face to face and in large group meetings. Through these interactions he was able to help educate thousands of people about Medicare and Medicare health plan options. As his clientele grew and to best serve them, Casey realized that he needed to represent many different insurance companies. In 2012 Casey became an independent insurance broker and began representing dozens of insurance companies in multiple states. Today Casey is licensed and has clients in Idaho, Washington, Oregon, Utah and Arizona. He has seen his business grow tremendously over the last few years. So much growth has come that in the summer of 2018 Generations Insurance opened their headquarters in Idaho Falls, Idaho. This office allows Casey to better serve his clients in all states as he has room for educational and sales meetings as well as space for his assistants and partner agents.

Casey is married to Alicia F. Peterson. Together they have 4 wonderful children. Sean and Chase are their identical twin boys, William is their “middle” child and Grace is dad’s little princess. What Casey likes most is to spend time with his family in the outdoors camping and off-roading. Trips to Yellowstone are common as well as getting out and exploring new areas of the west. He is active in his church and his community and is an Eagle Scout.
