What a wonderful staff! Had an urgent insurance issue that my GP would get around to in a few days. Instead, went to Dr. Treeter and they had it resolved in 20 minutes! What wonderful, helpful employees!

Manners of this doctor are not appealing to me as a customer I would choose elsewhere, not to mention I was double billed for the same service same date different claim number. How does that even happen? Of course my insurance caught it and they denied.
