Dr. Garrison grew up in the area of Mt. Vernon and Lancaster. He graduated from Lancaster High School and then attended Ohio University in Athens, Ohio. After graduating from OU, he entered The Ohio State Dental School and finished in three years. He graduated in 1980 and went back to southeast Ohio to work for two years. At that time he moved back to Columbus and opened his office in October 1982. He has been here ever since.

Dr. Garrison has strived to provide excellent general and preventive dentistry for families, and he continues to stress this as a basic part of his practice. With a combination of orthodontic and aesthetic services, he can make significant improvements in how people look. He also currently offers treatment for TMJ pain and discomfort as well as Sleep Apnea problems people may have.

Dr. Garrison is currently married with two children and the obligatory two dogs (who even though have regular names, usually go by doofus and dumdum). He loves cars, especially muscle cars. In his free time he likes reading Sci Fi books.
