Dr. Gregory A. Williams has dedicated his life to sharing his time and talents with his family, the patients at his thriving dental practice, and others around the world through his humanitarian efforts. When it comes to his patients, Dr. Williams is committed to providing compassionate, comprehensive dental care. Dr. Williams began his dental practice in the Tigard/King City area in 1998 after graduating from Oregon Health & Science University with high honors.

As a top dentist in Tigard, Dr. Williams also serves as a Master with the Academy of General Dentistry, which is an honor fewer than 1% of dentists achieve. He is also a Fellow with the International Congress of Oral Implantologists, a Diplomate with the American Board of Oral Implantology/Implant Dentistry (ABOI/ID), and a Fellow in the American Academy of Implant Dentistry. As an adjunct clinical instructor and student mentor at OHSU, Dr. Williams works with and instructs dental students on a regular basis. Dr. Williams has also developed a passion for humanitarian work at home and abroad. For years, he hosted one of the largest clinics in Washington County during the national Give Kids A Smile campaign. Since 2005, Dr. Williams has traveled annually to remote areas of the world including most of Central America, Peru, Ecuador, Samoa, India, and Nepal providing dentistry to thousands of people, many of whom have never seen a dentist. Shortly after one of these trips was when he and Dr. Scott Dyer co-founded Wide Open Humanitarian, Inc. Established in 2007, this not-for-profit organization brings dental relief to the poorest of the poor throughout the world, instructs the dentists in these remote areas regarding practical techniques, and helps pave the way for future organizations to set up ongoing clinics.
