I really have to say that this is the best dentist. I've put off going to dentist for many years of my fear but the welcome experience and treatment I got from Damien and leona was incredible. I'm looking forward to going back for my check up. if your putting off going to a dentist for whatever reason please dont. I'm now questioning myself now why I didnt do this years ago. thanks so much Damien and leona x

The doctor works very fast and efficient. The nurse is kind and friendly. The prices are quite reasonable. I am happy with my treatment and definitely will come back again.

I have been to several dental clinics in Letterkenny, but 03 is the best by far. They are highly professional and polite. I had a wisdom tooth extraction, and it went great. I will be returning to the clinic for all of my dental needs. They are brilliant, do not hesitate to give them a call.

Going to the dentist before, I always had feelings of trepidation- but thanks to Mr Flanagan not anymore.The moment I entered his state of the art surgery Damian put me totally at ease. He talked me through all my various options and throughout my treatment explained what he was doing. I had root canal treatment, crowns and veneers which lots of my friends have complimented me on. I would have no hesitation in recommending Mr Flanagan for his professionalism and his wonderful staff.
