Meet The Doctors

Carol O'Brien, DDS

Hello, and welcome to my practice! I'm Dr. O'Brien, and I truly love being a dentist. I enjoy meeting new people and becoming a part of their lives, while helping to maintain and improve their oral health. I see people from all backgrounds and ages, and it is fun to be able to connect with each patient. Even in the question of UW vs. WSU, I can say I'm BOTH a Dawg and a Cougar!

My education is as follows:

  • Washington State University – Bachelor of Science Degree in Civil Engineering
  • University of Washington – Doctorate of Dental Surgery

Although I finished with my formal education years ago, I feel it is vital to stay up to date on emerging dental technology and practices. That is why I am involved multiple dental study clubs: The Dental Collegium Study Club, a local Spear Study Club and the Tacoma Implant Study Group.  I am also a member of the Pierce County Dental Society, the Washington State Dental Society and American Dental Association

In addition to practice management courses, I also take ongoing courses in aesthetics and dental cosmetics. I enjoy my continuing education as it challenges me to grow and keeps me updated on the latest dental advances, so that I may pass on the best possible services to my patients.

I grew up in the northwest and am proud to call Washington my home. We live in a beautiful area! University Place and Tacoma has changed a lot in the past few years, and I'm honored to be a part of this community as it changes and grows. I hope you'll become a member of my family of patients.
