I saw him one time and he had good advice as a dermatologist, but he was double billing the patients. They insisted on a cash payment at the appointment time, but then also billed my insurance. I found this out after I paid cash at the office time and then presented the cash paid bill to my insurance for reimbursement. I never went back there. Be careful on his billing practices. He may have been doing this for years of time.

I used to go to Dr. Marnocha when he practiced in Green Bay. I have no problem with Dr. Marnocha's competency as a physician. It was his personality that bothered me. I think he was burned out. He would be working on me while I was lying on the table. Then he would turn around to enter his notes in my chart. I would sit up. That just irritated the h*ll out of him. He would snap, "Lie back down...it helps the blood to clot." (There isn't really any blood when he is picking on a zit). I think he is just a major control freak and doesn't want to feel rushed by the patient sitting up. Finally, one day I just told him "Screw you...I'm an adult and won't allow you to treat me so rudely."
