Tim was a great mentor to me at the William S. Middleton VA Hospital. He patiently taught me how to repair and rebuild wheelchairs. It was a great privilege to know him.

First met Tim when we both served in the 31st Med Group, 7th Med Brigade. Tim was the consummate professional officer and truly a kind and caring person. While he will be missed by many on this earth, he is surely at peace among the angels now.

Nothing but great memories of Tim. We served together in Washington D.C. and at Fort Carson when we were building the new hospital.
