Dr. Dallin Palmer

Dr. Dallin R. Palmer grew up in Utah where he enjoyed the rich outdoors and adventure the state offers. He loves the open wilderness and is an avid backcountry skier. He also enjoys water recreation, biking, golf, soccer and almost all sports.

After high school, he served a two-year full time mission in Italy for his church, and later met his wife. He and his wife were married in 2004 and now have two wonderful children. Dr. Palmer graduated from the Kornberg School of Dentistry at Temple University in Philadelphia, where he earned his DMD. He had the distinct privilege and opportunity to travel to Haiti – the poorest country in the Western hemisphere – and provide dental treatment to hundreds of people who are otherwise without access to medical or dental care. Dr. Palmer has always felt a strong desire to help others, which greatly influenced his career choice in dentistry.

Dr. Palmer has gained excellent clinical training, and enjoys all aspects of general dentistry including, restorations, crown and bridge, extractions, root canal treatment, denture needs and implants, and is Invisalign certified. His focus is on you, the patient, and is committed to providing an enjoyable and comfortable experience while delivering high quality care to meet your needs.
