M.S.
Dr. Thomas Whinery in Arlington works with a payment plan through a bank. You get a price from the dentist on how much the work will be, then work with the bank to get 12 months to pay it off with no interest. It's a good deal.
He is a really fabulous dentist. Makes recommendations about the work, but understands financial concerns.
