Jonathan S. from Seattle, WA (Source: Yelp)


I’ve had a vastly different experience with Dr. Cohanim than the other reviewer. I had previously visited another orthodontist but didn’t feel like they listened to my concerns. At Smileworks, however, Dr Cohanim and his staff were very patient with me, listening carefully to my questions and talking through all my options. This has continually been the case throughout the past 9 months that I’ve been a patient (I’m doing invisalign braces treatment). What’s more, they’ve been super-flexible with me — I’m a business traveler, out of town almost all the time, and Dr Cohanim has gone out of his way to work with my schedule. Certainly, it’s no fun to wear braces as an adult, but I’m thankful that I’m going through this experience under the thoughtful and considerate care of Dr Cohanim.

Dr. Cohanim boasts an amazing portfolio with great success stories, including my own! He also has an extremely kind persona while being firm and professional. I also appreciate the way my own ideas and aesthetics were incorporated from the start. The minute changes and tweaks are what really refine your final look, and it truly seems like an art. Dr. Cohanim is truly a master in his field with many satisfied clients. Jessica and Patricia also provide great support for Dr. Cohanim. Communication with the office is prompt if not immediate. Jessica is a very kind and seems extremely proficient, a great support arm for Dr. Cohanim. Patrician works magic for the office, accommodating my completely inflexible work schedule. So as I carelessly knocked my brackets off, broke the hardware or lost my post-braces retainer, these two accommodated me promptly, with kindness, and a smile. As of this post I’m braces free and couldn’t be happier with the entire 2+ year experience, start to finish.

I had a treatment here at Dr. Cohanim’s office. I had to get jaw surgery and the Dr. and the Team were an extraordinary. These guys are awesome as I had to get through the tough times and I would recommend anyone who is thinking about getting a consultation for any dental work!

I have had par-exelence experience with Dr. Cohanim, so satisfactory so that I would fly each month from New York to Seattle just to see see him and then would return back to New York very same day. Trust me, spending 6 hours flying back and forth between New York and Seattle is not fun, but the time and money I have spent was worth every penny. Dr. Cohanim set a clear treatment goal and I have obtained more than satisfactory result. I would strongly recommend him as your orthodontist. Based on my specific treatment plan, I have carried invislighn and then switched to braces. The staff is super friendly, welcoming and approachable. They will work around your schedule. You can share your concerns and ask your questions to Dr. Cohanim. I did and he always listened to what I thought and helped me to make most suitable decisions. Again, great doctor, nice staff and overall-very satisfactory result!!! Go for him, you

Dr. Cohanim and his staff are top notch. They came to me highly recommended and I am passing along that high recommendation. Attention to details, easy to work with when scheduling, willing to coordinate care with other providers. Your search for an experienced professional Orthodontist is over. You’ll note their quality on your first visit.

    Kristin G. from Seattle, WA (Source: Yelp)


    My son has been a patient of Dr. Cohanim’s for several months. While we are still in the beginning stages of our relationship, I can share that we are extremely pleased! Dr. Cohanim and his wonderful staff have helped my son, who was extremely reticent about the prospect of braces, feel comfortable and confident about the entire process. Dr. Cohanim is very receptive to all of my son’s questions and concerns and his staff is extremely friendly, welcoming and patient. I am very happy with our choice to work with Dr. Cohanim’s team.

    Mike W. from San Francisco, CA (Source: Yelp)


    Just an update, I completed the orthognathic surgery part 3 months ago and it all work out great. It actually healed up a lot faster than I expected and I’ve experienced no complications whatsoever. The first week or so after surgery was a bit rough, but it’s surgery, so I was somewhat expecting it. It’s all downhill from here with only a few more months of invisalign. Overall I have had nothing but a positive experience

    David Glick (Source: Google)


    Dr Cohanim and his staff are excellent. My dentist recommended him and they are familiar with a lot of orthodontists in the area. I elected to go with Invisalign to correct my bite. Dr Cohanim was thorough and paid close attention to the smallest details. If there was an issue he corrected it and in the end the treatment was successful. The staff was helpful with understanding payment options to include my first time use of a FSA/HSA. I highly recommend Dr Cohanim.

    Timm C. from Libertyville, IL (Source: Yelp)


    I would give (and have given) anyone a referral to Dr. Cohanim. I was hooked from the first appointment when I walked in the door and found one of my favorite people sitting behind the desk (Patricia, formerly of Guy Roberts, DDS). Then Shanda and Jessica reaffirmed my feelings by being so friendly and professional. Finally, Dr. Cohanim clearly knows his stuff. He is very direct and not longwinded. Ok, his timeline guess for my care was off by a bit- but that is more a problem of my mouth than his estimate- lol. One HUGE star alone is for the fact that I think the longest I have ever had to wait for my appointment time was 5 minutes.This is very important for those with busy lives. One word if you are considering braces- GO! Plus the view out the windows while you’re in the chair are gorgeous.

    Hilly F. from Seattle, WA (Source: Yelp)


    good service, very flexible, relaxed , and comfortable, invisaline has been a breeze, i was recommended to this clinic and am very happy with this experience. a far cry from the work done to my daughters teeth in bellevue many years ago now. which became an 8 year ordeal with damaged cracked teeth as result.. i like the no nonsense approach, and the straight forward advise.

    Aya Hamilton (Source: Google)


    Dr. Cohanim came highly recommended. He and his staff were superb. Appointments were easy to schedule and they were extremely efficient once you arrived in the office. They were always timely, never had to wait. Pleasant, accommodative, professional and skilled. If you can get in and out of your appointment within 30 minutes (which for many of the appointments you can), then the parking is free in the building.

    Carly A. from Seattle, WA (Source: Yelp)


    I recently got my adult braces off and couldn’t be happier with the whole experience, from start to finish. Had I known it could go as smoothly as it did I probably wouldn’t have put it off so long! The number one reason I enjoyed the experience is because of everyone at Cohanim Smileworks. Patricia is the kindest person and I love seeing her first thing when I walk in, and last person as I walk out. She does an incredible job of getting me in when needed at a time that works with my schedule. Jessica is so knowledgeable and helpful with everything she does during my visit. She didn’t even laugh when I told her my irrational fears when getting my braces removed. My only complaint is she isn’t there at all of my appointments 😉 Dr. Cohanim is skilled and is really good at listening to any concerns I have. He made things easy and painless and I wish I knew more people that needed braces so I could send them his way.

    Patricia R. from Federal Way, WA(Source: Yelp)


    My family & I have been cared for by Dr. Cohanim & his wonderful staff since 2001. Initially my ex-husband & I began our treatment. After such a pleasant experience we referred my younger sister who at the time was seeking an orthodontist. Then once our children were old enough we took them in for their consults. Having started their treatment plan at an early age we saved hundreds of dollars. I highly recommend Cohanim Smileworks. Dr. Cohanim has done a excellent job. My family & I appreciate his care & genuine kindness over these past 15 years. We like him so much that even after moving to Federal Way we don’t mind driving into Seattle for treatment. Although at times, I kind of wish he still had his Federal Way office.

    Lisa B. from Seattle, WA (Source: Yelp)


    My daughter has been a patient of Dr. Cohanim for the past three years. Dr. Cohanim has a quiet, relaxed demeanor that my daughter appreciates. The staff is friendly and the office is modern and has lovely views of the city. The patient base seems to be primarily children and teens. In talking to other parents in the waiting room, this is very much the Bertschi, Bush, SCDS, and UCDS set which is somewhat amusing. The quality of care is excellent, and as a professor at the UW, I believe Dr. Cohanim is up on the latest techniques.

    Patricia M. from San Francisco, CA (Source: Yelp)


    I’ve always felt if you can’t say something good don’t say it at all and that goes 10000x for these times. You never know if someone has just lost a loved one and has to work through it. Or whether you’re simply having a miscommunication. Smile-works is a lovely orthodontic office with compassionate professionals working together to offer a kind experience. Let’s give each other the benefit of the doubt and be kind on Yelp reviews.

      Lisel K. from Tacoma, WA (Source: Yelp)


      I really can’t imagine a more positive orthodontic experience than with Dr. Cohanim, Patricia and Jessica. I feel very fortunate my dentist referred me to this extremely knowledgeable, experienced and professional team. The quality of care has been consistently exceptional, as well as the ease of scheduling appointments. I couldn’t be more satisfied with my patient experience and Dr. Cohanim’s office has been an incredible support team in navigating a complex case that required braces and a double jaw surgery. I had an appliance come lose the night before my surgery and Dr. Cohanim made special arrangements to repair my braces and ensure the surgery went smoothly. Thank you Cohanim Smileworks team for providing such outstanding service at an affordable price. Truly a gem in the Seattle area.

      Jim Honan (Source: Google)


      Dr. Cohanim and his staff did a perfect job giving me a new smile with exceptional attention to detail. Every visit was a pleasure and I never waited for appointments. After returning several years from removal of braces (and my dog eating my retainers) I was treated like part of the family and given immediate attention. There are many choices out there, and I would definitely recommend Dr. Cohanim for all ages !

      If you are looking for an orthodontist whose medical knowledge is encyclopedic, treats the whole person, and takes the time to be caring even while maintaining a very efficient office, then look no further than Dr. Robert Cohanim. Several years ago, I began Invisilign treatments with a dentist. In hindsight, I should have consulted with an orthodontist, but mid-way through a treatment program that was not working, a friend referred me to Dr. Robert Cohanim who turned out to be a pioneer of the Invisalign technology in the Seattle area. Notably, he is also an associate professor at the Orthodontic Department at the University of Washington Dental School. Dr. Cohanim is a busy specialist with a high case load, but you’d never know it from his bedside manner. He is generous with his time. His manner is quiet and confident and he pays great attention to detail. He welcomes questions and provides thorough and understandable answers. He offers best advice and treatment during every visit—for every issue. The Cohanim “Smileworks” office is smoothly run. The support staff have been employed with Dr. Cohanim for many years and work smoothly and effectively together as a team. The office manager, Patricia, is efficient and sets the tone for a welcome and inviting experience in the office. A sweet touch to the atmosphere are homemade chocolate chip cookies that sit on a plate next to the coffee.

      I have been under the care of Dr. Cohanim and his wonderful staff for the past few years and cannot say enough positive things about my whole experience. From the moment I walked into the office, everyone put me at ease with their friendly smiles and genuinely caring demeanor. I was referred to Dr. Cohanim by my dentist for orthodontic treatment almost four years ago. I knew that I needed braces but had been putting it off. At my initial visit, Dr. Cohanim thoroughly explained the issues with my teeth, as well as, my treatment options. I found out that I needed to wear braces and have jaw surgery to correct my open bite. The thought of having surgery can make anyone feel frightened and overwhelmed, and at first I did feel this way. Dr. Cohanim was very understanding about my concerns and offered a non-surgical alternative. He explained the risks and benefits of both options. Dr. Cohanim took the time to patiently answer all of my questions and advise me about what would provide the best outcome for me. I never felt pressured to make a quick decision. I immediately sensed that Dr. Cohanim truly cared about what was best for me as a patient and that he had my best interests in mind. After much thought, I decided to move forward with jaw surgery. I asked which surgeon he would recommend and he suggested Dr. Feldman because of his expertise as a surgeon. They have treated many mutual patients, including his wonderful assistant Shanda. I decided to go to a consultation with Dr. Feldman as well as another maxillofacial surgeon in Seattle for a second opinion. After listening to both surgeons, I chose Dr. Feldman because both he and Dr. Cohanim instilled confidence in me. I had to wear braces for about one year and a half prior to my surgery and for a time after surgery. Although it is not the most enjoyable experience to wear braces as an adult, the end result far outweighs the temporary inconvenience. As my surgery date approached, I began feeling apprehensive and had a lot of questions and concerns. Dr. Cohanim walked me through the whole process with care and understanding. Shanda told me about her own experience and answered my myriad of questions. It was so helpful to talk with someone who had gone through surgery and I am so thankful that she shared her experience with me. Throughout my orthodontic treatment, everyone at Smileworks was absolutely wonderful to work with. The office is very organized and great about sending you appointment reminders and other important information. Patricia is the first person you see when you enter the office and she is a genuinely kind and friendly person. Shanda is a lovely person and fantastic at what she does. She is skilled and has such a gentle touch when adjusting your braces. Dr. Cohanim is excellent. He is an expert in his craft and I couldn’t have asked for a better doctor. He has fixed my bite and given me a great smile. Dr Cohanim and his wonderful staff have helped make my decision for orthodontic treatment and surgery one of the best decisions of my life. I cannot believe the difference it has made for me. I only wish I had done it sooner. I am truly grateful to Dr. Cohanim for his skills as a doctor and for his caring as a person. I would highly recommend him to everyone.

      Rena R. from Seattle, WA (Source: Yelp)


      First off, Patricia and Jessica are an absolute pleasure. They are personable and every time I come in for an appointment, it ‘s like I’m visiting with friends. I came to Dr. Cohanim for Invisalign, and I am almost done. I really feel like his main priority is making sure my teeth are perfect. He has gone above and beyond (ordering extra trays, scheduling extra check ups, ect.) and really made sure the results would be fabulous. The best part is, I was quoted a price for my perfect smile, and even with the extra trays, extra xrays, and extra check ups I was not charged an extra dime.

      Charna K. from Seattle, WA (Source: Yelp)


      My daughter has been going to Dr. Cohanim for these past few years. Although she is now away at camp, I can say that both she and myself are extremely pleased with his work. He is very professional and I have complete confidence that he is practicing the best up-to-date orthodontics available. My daughter actually looks forward to going to the dentist…not her dentist…her orthodontist!

      Lydia Fong (Source: Google)


      Thank you everyone for your professionalism, hard work, and commitment to excellent orthodontics. I can eat better and talk better now. Also, I get a lot of compliments on my smile and teeth. You guys are such an amazing team. Thank you so much for positively impacting my life in so many ways.

      Jake Bacon (Source: Google)


      Dr. Cohanim has been wonderful to me. He listened to my concerns and explained or answered all my questions about the process and what he was looking to accomplish with my treatment. His staff was also great to interact with, and very accommodating (when possible) of the few last minute schedule changes that I ended up having over the course of my treatment thus far.

      Nebiat T. from Seattle, WA (Source: Yelp)


      Dr. Cohanim, Patricia and Jessica are fascinating professionals: I am almost approaching my first year of having my braces. The team is consistent in the way they communicate with, explain and answer my questions. Their professionalism is flawless. Dr. Cohanim, Patricia and Jessica speak with soft and caring manners; they make me feel very comfortable to ask questions and explain things very patiently and slowly-I can say with confidence that they are culturally sensitive and respectful to their clients. Their building has parking garage and the first half hour is free. Should you stay in the office more than half hour, which is rare case, they validate your ticket. The office located in the 5th floor and affords beautiful view. I look forward to attend my appointments! I recommend Dr. Cohanim and his amazing staff to anyone. Nebiat Tessema, MSW.

      Dr Cohanim and his staff are extremely pleasant and very accommodating to work with. Both of my daughters have had great experiences. Each appointment is at the exact time it’s scheduled and quick making it very easy to drop by for an adjustment and continue on our way. I would highly recommend this Cohanim Smileworks!

      Sheri H. from Seattle, WA (Source: Yelp)


      I have been working with Dr. Cohanim and his team for several years now. I have a complex set of concerns that stretch well beyond basic orthodontia and have intersected with multiple oral health providers over the past few years. His service has shone above all others. He really listens to my concerns, always respects my chronic pain, and has devoted time and attention to helping me seek solutions well beyond simply providing my orthodontia. I cannot recommend him highly enough.

      Daniel Chercover (Source: Google)


      Both of my daughters enjoy coming to Dr. Cohanim’s office for their appointments. The results in my older girl’s smile are remarkable. His staff are friendly and efficient. The office manager Patricia is incredibly organized and personable. The reception area is comfortable and inviting; with a fish tank and a coloring corner for young ones. There’s even hot cocoa and cookies. They treat us like family.

      Sandi Whiton (Source: Google)


      Every aspect of this office is top notch! They are accommodating, caring, and incredibly professional. My 16 year old is super happy with the Invisalign, and he feel so comfortable with every member of the staff. They actually take the time to get to know you and care about everything associated with their work. Don’t hesitate to go to Cohanim Smileworks!!! They’re the absolute best in Seattle.

      Hannah N. from Edmonds, WA (Source: Yelp)


      Dr. Cohanim, Patricia, and Jessica made the entire “adult-with-braces” experience not only bearable, but almost enjoyable. They are all patient, kind, informative, well educated professionals who gave me many options, flexibility, and guidance through the whole process. They’re prompt in returning my calls/emails, they met me after hours a couple times for “braces emergencies”, they worked with my school and work schedule, they were always on time and never made me wait to see them, they’re extremely organized, have excellent communication skills, and are just great people in general. I truly looked forward to each visit, and appreciated Dr. Cohanim’s patience as I asked many questions over the years. I had a very complicated situation, and was so impressed with the planning and coordination between these guys and the Dr. Wasson’s oral surgery. Not only that but I honestly feel that these guys went above and beyond to make this process as painless as possible. I’ve come to truly value their presence in my life, and would recommend them to anyone and everyone who needs any orthodontia work.

      Jim K. from Seattle, WA (Source: Yelp)


      Unsurpassed expertise and professionalism. My three children and I are completely satisfied with Dr. Cohanim and his efficient, friendly staff. Dr. C is calm, good-humored, meticulous and technically adept. Over the course of treatment (now completed) our dentist regularly confirmed the quality of his work. Appointments were easy and always on time. We typically schedule simultaneous appointments -very handy. Convenient location. Excellent service and value.

      Diane Wolman (Source: Google)


      I was referred to Dr. Cohanim when two brackets fell off of the surgical braces that I had installed for a TMJ surgery in Florida a few weeks ago. Dr, Cohanim and his office staff couldn’t have been nicer. It was an emergent situation and that got me in same day, which was a tremendous relief. I was very impressed by everything about the process.

      Lexy W. from Seattle, WA (Source: Yelp)


      Two of my young children are a year into what will likely be years of treatment with Dr. Cohanim. I feel like they are in excellent hands. The staff is extremely professional. The office is comfortable, clean and open. Dr. Cohanim answered all of my questions and never seemed rushed. I appreciate that he’s a professor at the UW which means to me that he has the most current information about advances in his field. I’ve felt as though when there were options about treatment that the pros and cons were well explained so that I could make an informed decision for my kids. In contrast to a negative review below, in one case, Dr. Cohanim referred us to a (terrific) pediatric dentist for an extraction so that we could avoid general anesthesia with an oral surgeon.
