My experience so far for my family and I have been positive with Dr. Mark and his staff. His hygenists, although different on all three of my visits, have been very pleasant and seem to do a good job with cleaning my teeth. His rates seem a little high, but he does offer a discount for cash paying patients. He has good treasure box of gifts for child patients to chose from (ei my son got a big bag of marbles). I would like to see the fancier Oral-B toothbrushes given after each cleaning rather than some of the cheaper brushes given out. Dr. Mark seems to be a nice man with an upbeat personality. I would recommend the services of Dr. Mark.
