More about Dr. Rooz's journy to orthodontics

Dr. Rooz and his family live in Sammamish. He met his wife Elly – a New England native – in Boston. They were both excited that soon after relocating to the PNW it felt like home, and they’ve decided to stay here and raise their son, Milo Kalhor.

Dr. Rooz Khosravi interest in dentistry began early in his life, as he is a second generation dentist in his family. 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.

The joy of impacting others’ lives by improving their oral health is one of the main reasons Dr. Rooz decided to pursue dentistry. As an orthodontist specialized to move teeth, he sees the influence of a healthy and beautiful smile on children, teenagers and adults and enjoys being a part of this process for them.

Dr. Rooz obtained his dental degree (DDS/DMD) from Azad University in Tehran. Following his dental education he decided to move into the field of basic sciences, beginning with a move to Montreal to pursue his graduate training in oral health sciences.

He studied the relationship between diabetes and periodontal disease as part of his Master of Science degree at INRS-IAF. Following his graduation, Dr. Rooz again relocated, this time to Boston where he obtained his PhD in Oral Biology from Boston University. His studies in this degree program focused on bone fragility under diabetic conditions.

It was after these two degrees in the basic sciences that Dr. Rooz decided to transition back to the field of clinical dentistry, taking with him a deeper knowledge of bone biology, which made him keenly interested in the field of orthodontics. Dr. Rooz enrolled in the orthodontics program at the University of Washington, one of the top orthodontics program worldwide.

Love Dr. Rooz i have worked with him, had my braces done by him and now my son is in treatment with him!!! Best Orthodontist in Sammamish very friendly and experienced! I refer all my friends and family to him!


Dr. Rooz is such a unique, intelligent, incredible orthodontist. He has taught me SO many things and he has challenged me when I didn’t think I could be challenged anymore. He does outstanding work and you would be blessed to have him as an orthodontist or as an employer. By far the best Sammamish orthodontist I have met. I wanted to be an orthodontist for ever, until I met a different doctor who did not like his job…


Dr. Rooz is such a smart & cool orthodontist in Sammamish! He uses the latest technology to customize treatment plan for every patient, truly delivering Personalized Orthodontics! If you want the best treatment for you and your family, you’ve found the perfect office.


I have been to two other orthodontists in Sammamish and I guarantee that this is the best. They were very patient and completely fixed my overbite. While another orthodontist wanted to completely remove a tooth, Dr. Rooz and his team found a way to fix my smile with angling and teeth shaping. I have had braces and regular Invisalign so I was very hesitant when they wanted to use his own type of plastic aligners. However, I found that they were extremely comfortable and I felt little pain using them. The plastic he uses is more flexible and smooth in comparison to Invisalign. The edges of the Invisalign are sharp and cut my gums but his aligners were really smooth. If you are looking for an orthodontist, Porth orthodontics are the way to go.


I highly recommend this Sammamish ortho! I was one of their first patients and they have great service! I am so satisfied with my smile after a year of braces! Dr.Rooz is great doctor and I couldn’t have had a better smile! They ensured a great smile and their staff was always welcoming! Additionally, they were always flexible to fit us in their schedule! This was the best experience by far I have had with an orthodontist!


I'm almost finished with my adult treatment (using conventional braces) with Dr Rooz at Porth. I’ve been really happy with my choice. Dr Rooz and his staff have been easily available for questions via text throughout my treatment, and the two times I’ve popped off a bracket I was able to come in for a fix very quickly. I also love that Dr Rooz teaches ortho classes at the UW. It’s so reassuring to see an orthodontist who is up to date on all the latest methods and really engaged with and knowledgeable about the science behind his treatments. I’ve always felt like the goals of my treatment at each step have been explained clearly, and my total treatment time is going to be a month shorter than the original estimate. The tooth pain that brought me to get my bite fixed has been gone for the last six months or so, and I’m so happy with the improved aesthetics of my smile already—I can’t wait to actually get my braces off next month! Thanks Dr Rooz!
