There are two reasons to avoid this practice: 1)
1) They see too many patients, scheduling backs up, and wait times are WAY TOO LONG.
2) When they incorrectly billed my insurance and I refused to pay them directly full list price for their billing mistake, I was sent to collections. Even after my doctor appealed to their VERY unpleasant billing staff to clear up my account, they refused to remove me from collections, even though they admitted the billing was incorrect because they claimed too much time had passed.
Do yourself a favor and stay away from these people....money, not their patients, is their only concern.
