Dr. Dean Gregson

Dr. Dean Gregson attended Brigham Young University for his undergraduate studies before gaining his dental degree from Oregon Health & Science University in 1995. He’s been practicing in the area since then and completes 50+ Continuing Education hours a year! Dr. Gregson is a member of the American Dental Association®, the Academy of General Dentistry and the American Academy of Dental Sleep Medicine. He’s also received advanced training in restoring dental implants and treating sleep apnea.

Every few years, Dr. Gregson goes to Nicaragua and performs needed mission work with a local dentist. Many of those in our office and our community have contributed to these trips as well, by providing supplies, clothing and other necessities. Below, and on Facebook, you can see photos of some of his trips.

Dr. Gregson is married with four children and two grandchildren. Most of his time outside of the office is either spent with family or out in the Northwest hiking, biking, kayaking, etc.
