My husband went to see him. I wasn’t impressed by all the prescription meds he wanted my husband to go on. One of them made my husband ill. He was very rushed & talked rapidly & gave us the impression he was in a hurry. After seeing him, I don’t feel we have any better treatment or diagnosis than when we first started this process. There was no explanation for my husband’s acute sinus infections either. Basically, a waste of money.(As for billing, see my Unilocal review of COENT)
