Because of the poor rating, Dr. Timko was a second opinion for me. I was scheduled to have surgery on my tooth by a 4 star rated periodontist who spent 5 mins. with me and scheduled surgery. I decided to go to Dr. Timko and there was no comparison! Dr Timko sat and thoroughly explained why I would be waisting my money ($800.) to have him do the surgery. He referred me to a endodontist. My dentist agreed.
