The customer service, it's always there to help you with any questions or doubts that arise during your treatment process! I have been treated by them for 3 years now (and counting) without ever having an issue where they didn't follow through as promised - which makes me feel very comfortable about their work in general but especially when dealing directly w/them regarding my teeth whitening treatments!! They are also incredibly professional & friendly so working together has never felt awkward at all- even if we haven't seen each other since our last appointment months ago :) If anyone reading this wants great results from thier dental care then definitely give these guys @ la surprise group dentistry (@laserdentistgroup )a try. My smile looks amazing after just one session of laser therapy using laseersense technology! It really does make such A DIFFERENCE. !
