Made an appointment in April was given a packet for all requirements for surgery. None of the doctors accepted my insurance I had to go and find my own. When it was time for the clearance to come in they where slow adding it to portal. Fast forward next month I still need something else to be cleared for surgery. They have no bedside manner very unprofessional and I would not recommend them to anybody.
