About Mark

Mark Hoskinson, MD, grew up in Miles City, Montana, and has always liked the atmosphere of a small town. He says that Gillette is very much like Miles City in climate, topography and the friendliness of the people.

He comes to Gillette from Denver, where he practiced at Kaiser Permanente for more than 20 years.

Dr. Hoskinson attended medical school at John A. Burns School of Medicine in Oahu, Hawaii, and completed his residency in Internal Medicine at St. Joseph Hospital in Denver.

Two years ago Dr. Hoskinson was chosen from Kaiser’s 1,200 physicians as its Teacher of the Year. Has also received the Permanente Award, given twice a year by Kaiser physicians.

The biggest incentive for Dr. Hoskinson to leave Colorado after so many years was the chance to practice medicine alongside his son, Dr. William Hoskinson, who is a hospitalist at Campbell County Memorial Hospital.

As an Internal Medicine specialist, Dr. Hoskinson is passionate about improving quality. About 30% of his time at Kaiser was spent managing care coordination for patients with chronic conditions like diabetes and chronic obstructive pulmonary disease (COPD). He believes that implementing quality measures can touch many lives and help physicians improve outcomes for their patients.

Dr. Hoskinson is looking forward to becoming a member of the Campbell County Health Quality Committee once he learns the routine in his clinic.

Please welcome Dr. Hoskinson to Gillette and Campbell County Health.

Dr. Hoskinson sees patients ages 18 and older in Campbell County Medical Group Internal Medicine in the Main Clinic, 501 S. Burma Avenue, on the south side of CCMH. He is now accepting new patients. Call 307.688.3636 for an appointment. Learn more at
