Meet the Doctors


Dr. Derrik Johnson

Please help us welcome Dr. Derrik Johnson to Hover Dental Group.

Dr. Johnson is a Colorado native, originally from Lakewood, CO.  After attending the University of Colorado-Boulder, where he majored in Biology and Music, Dr. Johnson moved to Fort Collins before attending dental school.  It was in Fort Collins that he met Dr. Kochevar while working as his dental assistant!  Dr. Johnson later attended dental school at Boston University where he met his wife Shannan.

Desiring further education after school, Dr. Johnson joined the United States Air Force and attended a one year general dentistry residency, followed by serving 4 years as a Captain in the Air Force providing a wide scope of dental services to active duty airmen and retirees.

Since leaving the military, Dr. Johnson has traveled around the country following his wife who is still in the Air Force.  This has allowed him to practice in multiple settings as well as serving as adjunct faculty at a dental school.

Colorado has always been home and now that military service is coming to an end the Johnson family is coming back to Colorado.  He is a member of the American Dental Association, Colorado Dental Association, Spear Study Club, WhiteCap Implant Institute, the American Academy of Dental Sleep Medicine and the CEREC Mentor group.

When he’s not in the office, Dr. Johnson spends his time with his wife and their three kids camping and exploring the Colorado outdoors.  Despite all his travels, Colorado sports teams remain Dr. Johnson’s favorites and he looks forward to cheering them on in person again!
