Our Story


In 1979 H. Ray Harrell, D.D.S. and Nancy R. Johnson, D.D.S. were graduated from dental school in Kansas City, Missouri.  As the first married dentists in Tucson, Arizona, their practices started as associates.  They did not practice together originally, but in 1984 they merged their practices into an office on Campbell Avenue a bit further north than the current location.  In 1987 the practices were moved into the current building at 2710 North Campbell Avenue, Tucson, AZ 85719.  The doctors have practiced at this location ever since.  In 2014  Katherine A. Harrell, D.M.D., the daughter of Dr. Ray Harrell and Dr. Nancy Johnson,  graduated from dental school in Phoenix, Arizona, and began practice with her parents.  In June of 2016, Dr. Nancy Johnson retired from the practice of dentistry.  Dr. Ray Harrell and Dr. Katherine Harrell continued to uphold the proud family tradition.  In 2018 Dr. Katherine Harrell bought a practice in Costa Mesa, California, where she currently maintains a restorative dental office of her own.
