Dr. Arnold is the nicest guy. He is great at making you feel comfortable and "checking in" as he goes while doing fillings. He even massaged my jaw once as a long procedure was being done. He'll show you xrays and explain everything. I would give the rest of his staff a slightly lower rating. Billing was handled appropriately both when i've had insurance and paid out-of-pocket.
