What Our Patients Say

This was my first experience having an extraction and implant done in one visit. Dr. Atassi at Metrowest Oral Surgery was wonderful. He was kind, thorough and skilled. I was very pleasantly surprised at how easy the procedures went and the recovery was quicker than I expected. Dr. Atassi gave me his work cell phone number and advised me to call with any questions or concerns. One week after the procedure he texted me to make sure my recovery was going well. I 100% would recommend this dental surgery office and in particular Dr Atassi. Thank you for everything!

I am writing to express my heartfelt gratitude and commendation for the exceptional service I received at Metrowest Oral Surgical Associates. Recently, I found myself in excruciating pain due to an abscessed wisdom tooth. Understanding the urgency of my situation, my dentist advised that the tooth required immediate extraction and recommended your esteemed office for the procedure.Upon my impromptu visit to your facility, I was greeted with utmost professionalism and empathy. Despite the short notice, your team demonstrated remarkable efficiency and accommodated an appointment for me the very next day. This swift response was not only a testament to your commitment to patient care but also a significant relief amidst my discomfort.The day of the procedure, I had the pleasure of being attended to by Dr. John Ouano. His demeanor was nothing short of comforting and reassuring, which significantly alleviated my anxiety regarding the extraction. The procedure itself was executed with such skill and swiftness that before I knew it, the troublesome tooth was removed, and the pain that had overshadowed my days was finally alleviated.The relief I felt was immediate and profound, allowing me to look forward to the weekend with newfound optimism. Moreover, Dr. Ouano's thoughtful follow-up call later that day was a personal touch that truly elevated the entire experience. It is rare to find a healthcare professional who not only excels in their technical expertise but also in their ability to provide compassionate aftercare.The ambiance of your office further contributed to the positive experience. The aesthetic and comfort of the space, coupled with the friendliness and professionalism of your staff, created an environment that one could describe as a sanctuary for those in dental distress.In light of the outstanding care I received, I wholeheartedly recommend Metrowest Oral Surgical Associates to anyone in need of oral surgery services. Your team's dedication to patient well-being and satisfaction is evident, and I am profoundly thankful for the high standard of care provided to me.
