RETIRED PRESIDENT & CEO
Born in Glendive, Montana, I followed my family, first to Tucson, Arizona then to Minneapolis, Minnesota, where, after high school, I broke away, traveling to college at University of California, Berkeley, where I received a BS in Chemistry (with honors) and then off to grad school at MIT.
Making good use of my science background, motivated by a hungry family, I found a job as a management trainee in a community bank in Chicago. Thirty five years and two jobs later, I retired from an 18 billion dollar bank group as President and COO.
Most of my career had involved managing the credit function.
During my stay in Chicago, I spent 20 years on the board of an organization called LINK. LINK’s raison d’être is to face the challenges of education in the African American community by mentoring the students and financing their education in a private school environment. Of the approximately 70 freshman entering the program each year, 60 or so graduate from high school and 100% of those that graduate go on to college, most with 100% scholarships. During my 20 years on the board, I helped five students, most of whom are my friends today.
I currently live in Kelly, Wyoming with my sweet wife Lynne. We encourage long and frequent visits from my three children and their five kids, somewhat successfully.
