What Our Patients Say

We had a great experience with Dr. Atassi! He had great reviews on a local Facebook group and now I know why.Dr.Atassi is very warm and welcoming, funny.. He put my daughter at ease. He provided thorough and detailed explanation of the what needed to get done and why.Later in the day after the procedure, Dr. Atassi called to see how my daughter was doing. My daughter had a harder recovery from one of the impacted teeth and ended up with an allergy to the rinse. Dr. Atassi was readily available anytime to support us thru the recovery answering questions, providing reassurances etc. We also were leaving to go out of state and few days after the procedure and he offered to take a quick peek to make sure the recovery was on track.Seldom in the medical field these days do you find someone as caring and dedicated to their patients. It was much appreciated and sets his care at a whole other level!!

I had thought tooth removal (to prepare for implant) would be painful and difficult, but not at all. Dr. Atassi is extremely skilled and gentle and made the procedure easy. He is also a delightful, warm person. He was beey accommodating when I asked for little rests for my jaw when it got tired of holding my mouth open. He also made himself available by phone text at all hours for any follow-up questions. Never seen that before, anywhere!

I highly recommend the dental office where my son recently had his wisdom teeth extracted. They were absolutely amazing — from start to finish, the entire experience was smooth and comforting. The staff was incredibly caring, patient, and attentive, making sure he felt at ease every step of the way. They have continued to check-in on him even after the procedure.

I recently had my wisdom teeth removed by Dr. Atassi. I could not have had a better experience. I was nervous and Dr. Atassi made sure I was comfortable and felt at ease throughout the procedure along with answering any questions I had before and after. His staff and assistants are wonderful. They treated me like their own. I highly recommend Dr. Atassi. Thank you for your skill, kindness and helping me have a smooth recovery!!

I highly recommend Dr. Atassi and MetroWest Oral Surgical Associates. Dr. Atassi was kind and considerate of my nervous children’s feelings throughout the entire visit. From initial consult to having their wisdom teeth removed, we always knew we were in the best hands. He made this somewhat stressful process as easy as it could possibly be. Knowing I could reach out to him after with any concerns that might arise was so comforting. Total professional with a caring touch.

Both Dr.Atassi and the nurses who helped with my wisdom teeth removal were the best. I started to get pain and within a couple of days they were able to schedule me for my removal. I felt safe and comfortable the whole time, and appreciated the option to not have to take the more serious pain meds and instead do the shots in the extraction sites. Dr.Atassi continues to follow up with me on my recovery and I would recommend this place to anyone who is nervous about the whole procedure.

Outstanding preoperative teaching, thorough review of patient history and patient concerns with a remarkably pleasant and comforting bedside manner. The postoperative timely support via text was reassuring and alleviated concerns we otherwise would have carried longer without this convenience. Thank you MetroWest Oral Surgical Associates & Dr Atassi for making wisdom teeth removal as stress-free as possible.
