    Great dental practice. All staff are friendly and put you at ease if you are bit nervous of the dentist. I have tried a number of dentists and have now stuck with Damian for over 10 years. I highly recommend this practice.read more

    I highly recommend this fantastic surgery. Having cosmetic work carried out on my teeth has given me more confidence. First class service.

    Going to dentist before I always had feelings of trepidation, but not anymore! The moment I stepped through the door of Mr Flanagan's state of the art surgery all my fears were quickly dispelled. Damian put me totally at ease and talked me through the various stages of my procedure. I have had numerous treatments carried out including crowns and veneers which lots of my friends have commented on. I would have no hesitation in recommending Mr Flanagan in returning to his surgery and being treated as professionally as I was.read more

    I first visited the O3 Dental Studio in Ballymena in 2003. Right from the first time I met him I was impressed by Dr Damian Flanagan. I was very nervous as I knew I needed a lot of work done on my teeth including cosmetic dentristry. Damian's compassionate and calm manner put me at my ease right from the start. He always explains clearly exactly what work needs to be done including the cost. The work he has done since I first visited him has been of the highest standard. My regard for Damian is shown by the fact that since my first visit I have never again gone to another dentist in spite of the fact that I have a long journey to get to his studio.Over the years I have come to know Damian and his team - Karen his wife, and Sonya. They have always been so considerate and helpful I am delighted to get this opportunity to thank themJoan Kennedyread more

    I am petrified of the dentist and always have been, but I can honestly say Damian is the best dentist I have ever been to, very professional, explains everything and his dental studio is very clean and organized with all modern equipment. Can't recommend highly enough.read more
