Who We Are
Doctors You Can Trust
Our philosophy is simple: Listen. Evaluate. Diagnose. Treat.
Whether you are in a car accident, slip and fall, sports injury, or have chronic back or neck pain, Denver Pain and Spine is dedicated to providing each patient with a solution to return to a normal life.
The sooner you get treatment, the more chance there is for a cure. Every patient has a comprehensive evaluation where we listen to what is wrong.
Dr. Bennett then examines you and then puts it all together to form a diagnosis, or what is wrong.
We then tailor treatments to your individual needs.
Our personalized treatment approach ensures that our patients receive the highest level of medical and interventional care to reach their goal — relief of pain.
