G. Glenn Buchanan, DDS, PS
Dr. G. Glenn Buchanan finds tremendous joy in bringing out the healthy, beautiful smiles in patients of all ages.
Dr. Buchanan earned his undergraduate degree in Biological Sciences from the University of California at Irvine, and his DDS from Georgetown University School of Dentistry in Washington DC. With over 35 years of experience, Dr. Buchanan incorporates his expertise and current technology to provide his patients with the best in family, cosmetic, emergency, and comprehensive dentistry. He is a member of local and national dental societies and actively participates in continuing dental education.
Dr. Buchanan and his family relocated to Seattle from Southern California in 1992 and founded Gateway Dental Centre of Seattle that same year, followed by Reflections Dental Centre in West Seattle in 2005.
