Meet the Doctor

Tigard dentist Dr. Greg Williams has dedicated his life to sharing his time and talents with his family, the patients at his thriving dental practice, and with others around the world through several years of 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 Sciences University with high honors.

He continues a commitment of lifelong learning through maintaining a number of professional associations, such as the American Academy of Cosmetic Dentistry, the American Academy of Implant Dentistry, the American Dental Association, and the Oregon Dental Association.

As of the best dentist Tigard Oregon has to offer, Dr. Williams also serves as a Fellow with the Academy of General Dentistry and the International Congress of Oral Implantologists. As an adjunct clinical instructor and student mentor at OHSU, Dr. Williams is able to work with and instruct dental students on a regular basis.

Each year, he hosts one of the largest clinics in Washington County during the national “Give Kids a Smile” campaign every February. In the past, Dr. Williams has traveled to remote areas of Guatemala, India, Honduras and the islands of Samoa with Wide Open Humanitarian, and he traveled to Peru with Southern Cross Humanitarian in 2005 and 2006.

Shortly after one of these trips, he and his colleague, Dr. Scott Dyer, co-founded Wide Open Humanitarian, Inc. 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.


Dr. Williams has been married to his lovely wife, Michelle, for more than twenty years. Together they are raising seven children ranging from five to twenty-one years old, and can often be found coaching youth soccer or basketball as well as cheering at any of their children’s sporting and musical events. They enjoy time as a family through activities such as swimming, hiking, backpacking, cycling, and working or playing in the yard together.

Dr. Williams’ adventurous spirit is reflected not only through what he does for others, but how he chooses to enjoy his time away. Dr. Williams has participated in several Sprint, Olympic and Half-Ironman distance triathlons, and works with young men ages 16-18 in church, taking them on regular high adventure activities.

This kind of passion and dedication guides Dr. Williams through how best to care for his family, his patients, his local community, and those around the world.

"Best dentist ever!! I’ve been going here ever since I was a little girl at the old location. Their new one is so nice and spotless. I’ve never had any problems with my teeth and I owe a lot of that to them. I would recommend them to anyone."

"Dr Williams has been my dentist for over 15 years. I have absolute confidence in his professional abilities, and everyone in the office is friendly, professional, and highly skilled. I’ve had root canals and crowns, regular cleanings, and periodontal work done and have always been impressed by the care and followup."
