From what I can see from other post is that every AZ Perio office is very different. As for me my Periodontist is Dr. Dirk Donavan. His office is located in Central Phoenix. Adress: 5300 N Central Ave #130, Phoenix, AZ 85012. My experience was phenomenal! You couldn't beat the price, the customer service from the whole staff-- front office girls to the dental assistants-- and how smooth, almost pain--free the procedure went and there was really no pain after or during the healing process. I would definitely recommend this AZ Perio location!
