About Us

William J. Peterson, DDS

I earned a Doctor of Dental Surgery (DDS) degree from the University of Washington, School of Dentistry and then completed an Advanced Education in General Dentistry (AEGD) residency through the US Navy at Great Lakes Naval Station in Illinois. Following this, I served as a naval dental officer in Sasebo, Japan for three years, meeting the dental needs of overseas military families.

At the end of my service, I returned to my hometown of Bellevue and entered private practice with my friend and mentor, Dr. Larry Bouma. I eventually transitioned to sole ownership of the practice when Dr. Bouma retired in January of 2004. As the practice grew, I was pleased to welcome Dr. Donald Sunde as my business partner.

My wife, Laura, and I have been happily married for over twenty years and we have two beautiful daughters, Grace and Samantha, whom we adore. I am a committed Christian and strive to bring honor to God in all I do.

I favor a conservative approach to dentistry, focusing on prevention, education and a minimally invasive approach. To achieve this goal, our practice employs proven state-of-the-art techniques and technologies including digital X-rays, intraoral cameras, surgical loupes, diagnostic lasers and a CEREC 3D CAD/CAM digital impression and milling unit. Communication is essential to success, so I aim to clearly explain all options and recommendations to my patients.

Giving back to the community is one of my passions. Since 2015, I have served as a dental director for the Seattle King County Clinic, which provides free dental, medical and vision care to the underserved in our community. I am also an affiliate faculty member at the University of Washington, School of Dentistry. Recently, I was honored to become a fellow of the Pierre Fauchard Academy, an organization that recognizes professionalism, integrity and ethics in dentistry worldwide.

Donald A. Sunde, DMD

A native of the Pacific Northwest, I grew up in Olympia, Washington, and received a Bachelor of Arts degree in biology from Concordia University in Portland, Oregon. Over the next five years, I worked as a research scientist studying molecular lung biology for the University of Washington. I attended Midwestern University in Glendale, Arizona, where I earned a Doctorate in Dental Medicine (DMD) and went on to complete an Advanced Education in General Dentistry (AEGD) residency through the Northwest Dental Residency program. As a resident, I worked at the Yakima Union Gospel Mission Dental Clinic, providing high-quality comprehensive dental care for low-income families and a new beginning for those rising above abuse.

My wife Anne-Marie and I have been married for fourteen years and have two wonderful children, Ethan and Emily. In our free time, we enjoy introducing them to the great outdoors,whether it be camping or playing soccer, even in the rain. We are Christians and strive to live life with integrity, openness and honesty with a commitment to helping others.

I am dedicated to building strong relationships through open communication and empathy. It is my goal to provide a comfortable understanding of all treatment options and facilitate treatment that uniquely meets the needs of each person. I support an evidence-based and minimally invasive approach to dentistry, utilizing proven technologies (diagnostic lasers, resin infiltration, CEREC 3D CAD/CAM digital impression and milling) focused on the prevention and preservation of tooth structure whenever possible.

To keep up with the changes and innovations in dentistry, I continue my education by taking several courses annually. I stay current with advances in dental research and keep up with advancements in technology and improvements in providing excellent patient care.
