Learn more about Jeff
Jeff became interested in business sales when several of his long time business clients expressed a desire to exit their businesses and retire. Like most business owners, they were busy working in their businesses and rarely had the time to explore their options. Jeff took it upon himself to learn more about exit strategies and continued his research until he came upon the CBI TEAM.
At that point, he thought “Once I saw the process, the confidentiality, and the tools used by CBI, I knew that I had to become a part of the team.”
Jeff grew up in Enid, Oklahoma and attended college at Southwestern Oklahoma State University at Weatherford, Oklahoma. He spent 4 years in the military and graduated from Infantry Drill Sergeant School at Fort Benning, Georgia. He has a passion for music and performs regularly with his band Regal Country. He currently resides at Keystone Lake.
