I had a horrible experience as a patient of Dr. Guyer's. I completed extensive orthodontic work there (6 or so year's worth from start to finish) and so I was ecstatic to be done and very interested in keeping my teeth looking good. I was advised at one point to stop wearing my retainer...well I followed his advice and my teeth moved. I had to visit another orthodontist to have the problem corrected. My teeth were not correct all the way either. His staff was often cold an uncaring, and he did not seem to have much of a bedside manner either. My advice: stay away!
