About Colorado Gum Care
The practice has grown to five board-certified periodontists and two locations, but the foundation has not changed: thorough diagnosis, clear communication, and treatment that is in the patient’s best interest.
Welcome to Our Practice
Dr. Mark Wheeler founded Colorado Gum Care in 1986. Before opening the practice, he completed four years as a periodontist in the United States Army stationed in Landstuhl, Germany. He came to Broomfield and built a practice from the ground up.

At the time, patients in North Denver had limited options for specialist periodontal care. Dr. Wheeler changed that. Patients who came in the early years now bring their adult children. Referring dentists who started working with him decades ago still send patients today.
