I was referred to this place after receiving a referral from my dermatologist who said I had an abnormal mole that she suggested I have removed. I filled out some paperwork and sat with a guy for maybe 5 minutes max who said it would take 5 minutes to remove the mole. He then stated they'd provide me with a quote for the procedure. I have BCBS insurance and they said it would be around $500 to have it removed "cosmetically" and even more expensive through my insurance. I left concerned and upset. I decided to get a 2nd opinion so I want to another dermatologist who removed it FOR FREE with a $10 copay. Renaissance then proceeds to send me a bill for a $150.00 "new patient fee" despite providing literally no service at all. Total ripoff and waste of time.
