Mark was great, but I don't like that location, Newark. Being handicapped parking is always a challenge, actually missed an appointment due to not having any parking close by. Plus once you walk inside it's a long distance getting to the elevators. Truly miss the Limestone Rd location, never had Any issues there. Don't understand why the practice left??
