Dr. Nicholas Mooberry D.D.S.

Our office excitedly welcomed Dr. Nicholas Mooberry D.D.S. in June of 2017. Dr. Nick is a native Tucsonan and also a third-generation dentist. His grandfather and father both practiced dentistry here in Tucson.  He feels fortunate that he had the opportunity to work with and learn from their 85 years of combined experience. Northern Arizona University was where he studied for his undergraduate and then went on to attended the University of the Pacific Dental School.  He had the honor of salutatorian at U.O.P., and is a member of Phi Kappa Phi as well as Omicron Kappa Upsilon. After school he returned to Tucson and has been in private practice since 2006. One of the many aspects he enjoys about dentistry is helping patients solve their dental problems, whether they are simple or complex. Some of his professional affiliations include membership to The American Dental Association and Southern Arizona Dental Society. Outside of his profession, spending time with his family and experiencing the great outdoors are just a few things he enjoys. Dr. Nick looks forward to meeting you and helping you with your dental needs.
