Did you know that Colorado United was originally, and still is, Adams County School District 50's credit union? School District 50 Credit Union was founded in 1952 by Iver C. Ranum and John E. Flynn in order to serve teachers in the district. Their goal was to create a financial institution that allowed teachers a safe and sound institution to save and borrow at reasonable and affordable rates. After 50 years, our name has changed, but that philosophy still holds true.
