I have gone to Dr. Lehtman's office for a few cleanings and x-rays, and so far service has been prompt and adequate. Dr. Lehtman and the hygienists are knowledgeable and friendly. No pain or discomfort has been felt be me in the several visits I've made. The facilities could be a bit nicer and newer but in general the place isn't bad. Don't expect a spa though. As for billing and insurance, I have received a bill from the office when it should've been taken care of directly by insurance, but in the end, it got sorted out and I never had to pay anything out of pocket.
