I have been to quite a few dentists over the years and have finally found the right one. Dr. Mark is extremely knowledgeable, but yet easy to talk to about whatever questions I have asked. He cares about his patients' over-all health and gives great suggestions that have really made a positive difference in my dental hygeine. He also motivated me to be more aggressive and consistent in my dental care, as he explained what an impact it has on health in general. I travel from Butler (north of Pittsburgh) to Bridgeville (south of Pittsburgh) for my appointments and gladly do so as he has far surpassed anyone I've seen in the Erie, Cleveland and Butler areas.
