Meet the Doctors

We are local but world class

Dr. D. Hamilton Sims, DMD

Tufts University School of Dental Medicine

Dr. Sims discovered he wanted to be a dentist when he himself went through many years of orthodontics and maxiofacial surgery during his teen years. Because of his experience, he was determined to become the most empathetic and caring dentist possible.

Dr. Sims received his undergraduate degree from Tulane University in New Orleans and is a graduate of Tufts University School of Dental Medicine in Boston. Dr. Sims enjoys all facets of restorative and cosmetic dentistry. He continues to stay on the cutting edge of the latest advances with post-graduate studies and active participation in local and national dental organizations that include the American Dental Association, Oregon Dental Association, and the Academy of General Dentistry.

It’s increasingly rare in our fast-paced society to find a doctor who takes the time to build personal relationships. Dr. D. Hamilton Sims makes it a priority to know each of his patients and provides a lifetime of dental care by first learning what’s important to you.

Dr. Sims is also committed to having a well-rounded life. He and his wife, Francesca enjoy staying active and spending time outdoors. In addition, Dr. Sims is an accomplished musician who sings and plays guitar for Pacific Mean Time. Be sure to ask Dr. Sims for the latest recording!

Dr. Valerie Truhan, DMD

Oregon Health & Science University

Dr. Truhan grew up in Baltimore and earned her bachelor’s in Economics before realizing she would be better suited in the dental field. As someone who has always been meticulously organized, detail-oriented, and easy to connect with, dentistry has been the perfect fit.

Dr. Truhan graduated from Oregon Health & Science University, and since then has kept busy with private practice and volunteering with such organizations as Medical Teams International. For those who need additional help to relax their jaw muscles, she offers botulinum toxin therapy and would be happy to discuss if it might be a good option for you.

As someone who finds it imperative to listen intently to patients and their needs, prioritize prevention, and find reasonable solutions, Dr. Truhan is excited to join a practice where this is already imbedded into the culture.
