The family would like to thank Dr. Wiener and the entire staff at the Cancer Treatment Center, and the entire staff on the Oncology floor at St. Peter’s hospital for the care and compassion they provided.

A private family service will be held at a later date. In lieu of flowers, an account has been set up at Rocky Mountain Federal Credit Union in his wife Colleen Tesdal’s name to help with final expenses. You can make your donation at either branch, but please be sure to tell the bank representative to “share a comment” and leave your name so we know who it came from. Please visit below to offer a condolence to the family or to share a memory of Jeff.
