Top notch visit. Never felt rushed, answered all questions. Firm in a caring and concerned way w/o being pushy or rude.

Sarah and Dr. Bascom are truly the best. They are kind, caring, empathetic and easy to talk with. I sincerely appreciate you Sarah.. Doctor Bascom did a great job replacing my left hip andi I am grateful for his service throughout the process. If you are in need of surgery I highly recommend that the first phone call should be to the Westminister office on 144th or the Golden office. (Occupational Centers of Colorado) Coleman Jacques
