First visit to this office and everyone was so friendly and efficient. Dr. Clemenza was very informative and told me exactly everything he was doing. I will be returning for removal of another wisdom tooth. Probably the best dental experience I've ever had.

Dr. Clemenza and his staff are absolutely amazing and professional! I had one of my wisdom teeth removed today and he and his staff did an awesome job with the removal and the process as a whole. I would highly recommend Dr. Clemenza for all your dental care.

Dr Clemenza and his staff are excellent! This was my first implant. The process went smoothly and was essentially pain free. Everyone was pleasant. The practice uses state of the art technology to support the process. I highly recommend Keystone OMS!

Dr. Clemenza & staff are amazing! They make me feel great about myself and are rooting for me and my journey with my "all on fours"....top & bottom teeth due to be assaulted by a patient in the emergency room. Dr. Clemenza is an amazing oral maxillofacial surgeon and I have had amazing results and have exceeded my expectations! I only had pain for 4 days after surgery and after that absolutely no pain! The staff in the office are so professional and make you feel like part of the office family...I love getting to see them and updating them on life. If you are looking to get "all on fours" or any oral maxillofacial surgery...please don't go with companies that have commercials on TV. The best doctors/surgeons are the ones you hear about by word of mouth.
