About Dr. Rooz

Top orthodontist in Sammamish

Rooz Khosravi, DMD, PhD, MSD

Dr Rooz is an industry expert on digital orthodontics and innovative technologies who teaches other orthodontists.

Dr. Rooz Khosravi established PORTH Personalized Orthodontics in 2017 in Sammamish to offer a personalized approach to orthodontic treatment. He offers individually tailored solutions aimed at creating precision outcomes to deliver beautiful, confident smiles to each of his patients.

As a second generation dentist in his family, Dr. Rooz’s interest in dentistry began early in his life. He grew up spending lots of time in his mother’s dental practice, and learning the importance of deeply caring about patients of all ages.

Dr. Rooz was trained at the University of Washington, a world renowned program in orthodontics.  He holds a masters degree in oral public health and a PhD in bone biology. Less than 1% of orthodontists have such credentials, making him exceptionally trained and qualified in the field. He is also an assistant professor of orthodontics at the School of Dentistry at the University of Washington, where he teaches at both the undergraduate and graduate orthodontics levels.

Dr. Rooz is a diplomate of the American Board of Orthodontics, a commitment to excellence that is held by only 30% of orthodontists.

Dr. Rooz lectures nationally and internationally on digital orthodontics including 3D printing technology and a custom in-clinic aligner system.

Dr. Rooz Talks About 3D Printing Technology

Dr. Rooz developed the PORTH Clear Aligner system, an innovative method of creating customized clear aligners utilizing advances in technology and 3D printing. PORTH clear aligners are the next generation of clear aligners known as Invisalign. Porth aligners offer personalized features that companies like Invisalign or Clear Correct can't offer..

Personalized sammamish

Early in his residency at the University of Washington, Dr. Rooz and his wife went for a hike east of Seattle.

On the way home they stopped at Homegrown in Sammamish, and immediately felt something for this place. Dr. Rooz loved that Sammamish has a small town feel, but with a diverse population and a strong sense that it was on the brink of change. This town is growing in leaps and bounds, and he wanted to be a part of it.

A few weeks later, Dr. Rooz's real estate broker introduced him to TRF Sammamish Project and the rest is history!
