I just had a TMJ surgery from Dr. Keller and his team at the Mayo Clinic in Rochester, MN. It was my 7Th TMJ surgery, my first from him, him and his team of 9 Oral and Maxiofacial Docs are amazing! It was a 5 hour surgery with all 9 doctors in the OR. I am healing slowly buy surely, I would highly recommend him!!! He knows what he is doing, I should have gone to him after my 1st surgery, I guarantee, I wouldn't have needed 6 unsuccessfully TMJ surgeries
