The Kois Center is an advanced graduate didactic and clinical program for practicing dentist.

The curriculum is based upon the mission statement: “Enabling motivated dentists to achieve extraordinary levels, expanding knowledge and application skills in restorative dentistry.”

Dedicated to learning new advances in dentistry, Dr. Johnson pursues high quality, science based, dental education courses each year to broaden his understanding and to maintain his refined skills.

Dr. Johnson is committed to excellence and those around him cannot help but be positively affected by his dedication to it. Dr. Johnson is passionate about having a practice not focused on the volume of patients, but rather the individual care each patient receives.

He ensures this with his sincere approachability and attention to detail, creating an environment where patients can be certain they are being heard both from a cosmetic and functional perspective. By surrounding himself with excellence and a team committed to those same standards, Dr. Johnson has the privilege of forming trusting, lasting relationships with his patients while treating their dental needs.

Dr. Johnson has had the opportunity over the years to consistently give back to the Billings community through service provided for the Yellowstone Boys and Girls Ranch and Donated Dental Services. He has also provided free dental care for the Yellowstone Drug Court, which helps recovering addicts restore their teeth and improve their oral health. These services have helped recovering addicts feel better about themselves and to seek employment, which enables them to be united with their children and families.

Dr. Johnson is actively involved in church and civic organizations. He is an Eagle Scout and enjoys working with the scouting program and youth groups. He loves nature and when not at the office enjoys spending time with his family; four wheeling, hunting, fishing, skiing, and scuba diving.
