About

ADVENT is a highly polarizing clinic. Many patients are thrilled with the quick, effective relief they find for their sinus issues and praise the staff's professionalism. However, there is a significant number of negative reviews focusing on aggressive billing practices, surprise fees, and a feeling that the clinic is more focused on profit than patient care. It seems to be a place where you either get great results or feel like you've been scammed.
