Update by user Feb 12, 2014 Dr. Zietz has cleared my account with the collection agency Update by user Jul 29, 2013 I wish Zietz would pay me the money he owes me and stop sicking his wife on me. She made cheap comments after several of my many reviews about his cheap self. I could then afford a good dentist not a cheap skate like him. I never finished the cheap bridgework in Madison with Zietz as I was waiting for the credit he promised me to show up on a statement. I got a second opinion from another dentist, he thought Dr. Zietz did a cheap job too. He pulled the tooth that Dr. Zietz smashed in his many cheap attempts to put a simple cheap crown on a tooth. Original review posted by user Jul 25, 2013 Credit or discount promised in his own record. No corresponding credit or discount shows on billing record. Dr. Zietz would not consider ANY mediation from Better Business Bureau and lied about agreeing to the discount because it implied poor work or a mistake he had made. I obtained copies of my patient and billing records from his office and soon noticed that Dr. Zietz had made more than one mistake He re-cemented the same crown over a dozen times when he should have noticed by wiggling it that it was loose below the gumline and the multiple rootcanals in other nearby teeth most likely unnecessary because all pain and infections in the area of tooth #5 caused by Dr. Zietz leaving most of the nerve intact when he missed the root and put a post into my gum. I am following up with a complaint to the Wisconsin Dept. of Trade,Agriculture and Consumer Protection.
