Are you tired of being treated as a criminal due to your pain? Tired of going to clinics that force treatments that don't work or treatments you have already had in the past? Here at CIRCE, We evaluate each individual patient differently than other clinics, as we treat you how we would want to be treated. We give our patient's options of treatment and the patient's can voice there opinion in their own care.
