what adult patients experience at PORTH

My lower teeth were becoming increasingly crowded since high school. I had braces for a little while during high school and since, hadn’t worn my retainers. I knew I wanted to do clear aligners because they are discrete enough so that I’d be comfortable in a professional setting with them on. I watched a couple girlfriends have slight issues with by-mail aligner services so I wanted to avoid the same complications by going to an orthodontist. From the first appointment with Dr. Rooz- the process has been easy, comfortable, and rewarding! Within a week I already saw a change in my smile. He is fantastic about answering questions along the way and continues to show genuine interest in how the process is going for me. So happy I found Dr. Rooz and can’t be happier with the quick & painless results. Highly recommend!!

Dr. Rooz is truly an amazing Orthodontist, not only his knowledge and expertise  but also his dedication to his patients especially during  the COVID-19 crisis.  My son's wire on his braces came loose so I was worried that we would not be able to take care of it until the stay at home order was over.  I decided to text Dr Rooz hoping he could help and to my surprise we were able to schedule a visit on the same day. The office is thoroughly disinfected  and spotless, following rules of social distancing (my son was the only patient in the office and no other patients were in the office for the entire time of his treatment), Dr. Rooz wore personal protective equipment to ensure that my son was safe. I felt completely safe and extremely grateful that Dr Rooz would go out of his way to help my son and make sure that his office was safe!

Most businesses are shut down due to Covid 19, but after a video call with my daughter who was having discomfort, Dr Rooz determined the best option was to bring her to the office for treatment. He took the necessary precautions to keep her safe while being able to resolve the issue. We are so grateful he was willing to go above and beyond to care for her and are very pleased with how her treatment is going.

I started using metal braces for the first time back at the end of high school and continued into undergrad, some 8-9 years ago. Like many people do, I didn't follow my then orthodontist's instruction about my retainers and my lower anterior teeth relapsed.

Now I'm a dental student at the University of Washington and have been learning about clear aligners in my classes. I decided to try them out and looked for an experienced orthodontist near me. After a lot of online research I found that Dr. Rooz is a true leader in the field and his publications have been selected as top scientific resources in the field of dentofacial orthopedics, clear aligner therapy and orthodontic specialty. My experience with Porth has been amazing! All of the staff are friendly, professional and treat me like family and not just a customer. Dr. Rooz is great, I really appreciate that he takes the time to answer all my questions and makes me feel like a huge part in the treatment planning process. Also I love going to the office because it is a state-of-the-art facility with all the latest advancements in the orthodontic specialty. From intraoral scanners, to the dental chairs, to the in-house 3-D aligner printer. It truly feels like I've stepped into 2030. I highly recommend to anyone seeking their perfect smile!

I don't write reviews often but I loved Dr. Rooz and everyone at Porth! The office is so clean, nice, and high tech. You feel 100% comfortable with the treatment plan and he explains all the steps with great detail. I have had consultations from other orthodontist before and they didn't compare. Porth is really leading the industry with knowledge and customer care.

As a kid, I had braces and years later found myself wanting to correct my front teeth that had shifted. Since it was something minor, I was close to signing up for at-home aligners. Thankfully, I found Dr. Rooz and decided to get a consultation before making a final decision. From the very beginning I noticed how much he really cares about his patients and wants to help them achieve the smile they want. He listens to and addresses your concerns very thoroughly and is very knowledgeable. With any issue or concern I had throughout treatment, Dr. Rooz addressed them right away and took the extra time in helping me resolve them. He uses the most up to date technology (no uncomfortable impression molds) and the time frame for getting new aligners/switching them out is awesome (I had the Porth in-house aligners).

The office is beautiful and filled with a very friendly staff who makes you feel comfortable as soon as you walk in the doors. Thank you Dr. Rooz and everyone at Porth for my new smile and an amazing experience!

I wasn't sure how my treatment would go because the price quoted was a fraction of what I'd been quoted for aligners elsewhere. 5 months later, I'm already done and very happy with the results! I liked that Porth provides weekly aligners so you get to switch them out before they get gross. Dr. Rooz and his staff were wonderful, and the office is high-tech and beautiful. Also, they offer a range of appointment times, including Saturdays.

After years of suffering with crooked teeth, my daughter told me about Dr Rooz and his new orthodontics clinic PORTH in Sammammish.  It is quite a ways from where I live, but after meeting Dr Rooz and seeing his unbelievably modern and high tech office, I knew is was going to be worth the drive.  Dr Rooz is very engaging and so knowledgable about the latest and very best ways to correct bites and straighten teeth.  What should have taken over 12 months to correct only took 9 with Invisalign trays and I am beyond pleased with my new smile. Super highly recommended for both service and final product.  Thank you Dr. Rooz for making my smile perfect:)

Think you have a difficult case until you meet Dr. Rooz at Porth's personalized orthodontist.  After years of orthodontal work, going from one dentist to another and still not getting the result I want, I finally found Dr. Rooz and he restored my smile. And he did with so much knowledge, patience, and kindness.
Not only are you welcomed with an infective smile from both the receptionist and the dentist himself, you get to have some beverage while you wait and the calm, welcoming ambience of the office will make you not want to leave.
You are sure to get the personalized top-notch care you deserve from the time you step into the clinic thru the end of your treatment as he is a scholar and keeps abreast of the current medical equipment to provide the best care. His treatment is truly tailored and customized for your individual need
I can't stop showing off my teeth.

Looking for more information on treatment options at our orthodontic clinic in Bellevue to straighten your teeth or correct your bite


Clear aligner therapy is quickly becoming a popular option for many patients as they want to straighten their teeth in the most inconspicuous way possible. At PORTH Personalized Orthodontics, we provide Invisalign and Porth Clear Aligners. Dr. Rooz’s expertise in Clear Aligner Therapy helps patients straighten their teeth without braces.


Lingual braces are like traditional braces but are placed behind your teeth, instead of in front of your teeth. This is another fantastic option for those who want straight teeth but do not want to draw attention to their current smile. PORTH was established and specializes in customized advanced treatment modalities.
