Staff said that they were a "provider" on my insurance. Yes, I should have checked. They billed me for $618.00 for tests. I paid the bill IN FULL and then they turned me over to a collection agency. No one left in their office knows anything, doesn't return calls. They say they are waiting for Dr.Parilak to tell them something. In the meantime I have a collection agaency breathing down my back for a bill I have paid. Next stop, the Medical Board & an attorney.
