WARNING: These people are extremely rude, and they will scam you. They tried to bill my insurance $60,000 for a procedure that normally costs $4,000. They handle billing for many surgery centers. Their billing manager is Angelica Valenzuela. She has the worst customer service skills I have ever experienced. I recorded multiple conversations with her showcasing her terrible customer service skills.She will lie to you in order to get as much money as possible. On top of everything my procedure did not do a thing! It had no benefit to me whatsoever. These people are scam artists. Stay far away from any surgery center that they are in charge of!
