Meet Dr. Seldomridge

Dr. Seldomridge was raised in Lancaster County and is a graduate of Manheim Township High School. His 13 year association with the Naval Reserves and participation with several volunteer teams to Mexico have enhanced his professional skills. His particular areas of interest are implant and jaw and facial reconstructive surgery. He enjoys life long learning and teaching as evidenced by the amount of hours of continuing education in which he participates.

Dr. Seldomridge is a Diplomate of the American Board of Oral & Maxillofacial Surgery (Board Certified, 1990) and a Fellow of the American Association of Oral & Maxillofacial Surgeons (AAOMS) for which he serves as one of four Delegates from Pennsylvania to the national AAOMS House of Delegates.

As a youth growing up in Lancaster County and ninth generation of his family to live here, Gary was very involved in school, church and community activities including being a three-sport athlete, Eagle Scout, and coach of a large age group summer swim team. He enjoys following up on many of these past connections with his patients today.

Dr. Seldomridge is married to Christina (Newkirk) of Evergreen, Colorado and has two wonderful sons, Tyler and Benjamin.

Dr. Seldomridge is very active with the Pennsylvania Dutch Council of the Boy Scouts of America, serving 6 years as a scoutmaster of Troop 102, member of the Council High Adventure Committee and a co-contingent leader for two Council excursions to Philmont Scout Ranch in New Mexico, a sailing adventure at the BSA Sea Base in the Florida Keys, and two Canadian canoe/portage treks with Northern Tier and Birchbark Expeditions.
