What Our Patients Say

When the tooth pain increased, M.O.S.A was terrific in moving my appointment UP. This was feasible because I had flexibility to be able to make the appointment in a different location.
Very happy I experienced no pain at all with the implant replacement. Looking forward to the tooth insert when the post and bone graft are ready. Staff answered any questions I had before the procedure. Definitely recommend Metrowest!
From check-in to check-out, best experience ever with multiple tooth extractions. Extremely professional, attentive, and friendly staff! Everything was explained thoroughly and Dr. Youseff was wonderful! Highly recommended to anyone having to deal with oral surgery.
I am in the middle of multiple extractions and implants. Dr Youseff, the entire staff, and the whole experience has been truly exceptional. I really appreciate that Dr Youseff is always available to explain the procedures, what to expect, and to thoroughly answer all questions.
They take the time to explain everything and make you feel comfortable.
Excellent quality, care & communication!
Dr. Frangos is really good. Highly recommended.
Very good experience. They were quick, polite, nice, and efficient. Squeezing me in within a few days was great. I was so happy to have the problem fixed before the pain got bad. Thank you Dr. Ouano
Everyone there was very helpful. They were all very professional including the front staff. Dr. Jennifer & her assistant were excellent.
I dreaded going but it was not bad @ all. I even called them after the procedure twice regarding questions I had. Sean went to the back & got the doctor’s assistant on the phone for her to answer my question.
I would highly recommend them.
They squeezed me in last-minute for an emergency extraction, and it was a real life saver! Thank you!
Dr. Youseff was amazing and truly emphasized what it means to provide individualized patient care through the entire process of my wisdom teeth extractions. When my body had some complications with healing after surgery, he called me personally and was overly willing to provide anything I may have needed. He took further time from his busy day to see me again and provided some management care, all with a smile on his face and never while making me feel like a burden. His support team was amazing as well, ensuring I was very comfortable before my surgery and easing any anxiety. I would recommend him and his team to anyone!
Dr. Ouano was very professional, explained my diagnosis and performed a quick and painless extraction. The staff is very cordial and there was absolutely no waiting.
Dr. Youseff is a great doctor and made the wisdom teeth extraction procedure as easy and stress-free as possible.
From the initial consultation, Dr. Youseff examined my panoramic x-ray and explained everything in very simple terms so it was easy for me to understand. He explained up-front on how to prepare for the procedure and how the recovery will look like.
The procedure itself went very smoothly and I did not feel much pain during recovery. This was a slightly complicated procedure as well since I had an impacted wisdom tooth.
If you have to go through oral surgery, do it here. The Dentists are always great, as is the rest of the staff.
I just had a tooth extraction and the staff was very caring, they explained everything clearly

The doctor showed concern for me and explained step by step instructions so I would jump because I was a little nervous

This truly was the best oral surgical experience that I've ever had
Dr. Ouano is truly amazing! From the very first visit through my son’s wisdom teeth surgery, he made the entire experience smooth and reassuring. He was professional, kind, and took the time to make us feel comfortable every step of the way. The entire staff was just as wonderful—friendly, supportive, and attentive. We couldn’t have asked for a better experience!
Excellent,professional, the staff couldn't say anything bad from walking in the door to walking out the door. Everything was explained what was going to happen for my procedure from what I see everybody that works there treat ever patient with excellent service and professionalism. Definitely would recommend!!!!!!!
AAA+++ in all respects.
The whole team made my tooth extraction and implant so much better, easier and pleasant than I was anticipating Each person I encountered was extremely professional and kind. Highly recommend this practice. Great people , support and expertise.
Professionally run business!!
I went to Dr Ouano today for an extraction and implant. I was extremely anxious but he quickly put me to ease and was very knowledgeable. In and out quickly and did a fantastic job. 10:10 recommend.
I had been ignoring my wisdom teeth for years purely out of anxiety. I finally made the decision and had them removed with Dr. Youseff. He and his team had the best bedside manner. Before I knew it, the procedure was done and I was on my way home.

Thank you to everyone at Metrowest Oral Surgical Associates. I feel so lucky to have been treated so well, and I’m glad to be starting the road to recovery.
i DON'T GO LOOKING FOR AN OPPORTUNITY TO HAVE A TOOTH PULLED, BUT METROwEST HAS BEEN THERE FOR WHEN i NEEDED IT DONE. i AM ALWAYS AMAZED AT HOW SKILLED THEY ARE AND HOW QUICKLY THE ORDEAL IS OVER
Everything from scheduling to the procedure was a breeze, my only gripe is that I felt rushed out.
I just wanted to share my awesome experience with Dr. Atassi and the whole team. Going in for extractions and implants had me super stressed - seriously, anxiety overload! But honestly, they were incredible. They made the whole thing so much easier than I ever expected, and I felt completely at ease the entire time. I’d recommend them to anyone, hands down! Thanks again, Dr Atassi and team!
