Dr. John Siebert IS A ****. He ****ed my face during surgery, conducted unauthorized surgery on my back, and cut my chin open without anesthesia after I complained. He lied about the nature of the surgery. DONT LET HIM NEAR YOU! He is a sociopath. I was so traumatized, I refused the 2nd part of the surgery. So my face is half complete.
