Dr. Zadieh is truly the best! I didn't have a dentist in AZ and one of my fillings fell out over the weekend. I called his office on Monday and I was in to see him by Wednesday. He ended up fixing my filling and another filling that a different dentist did wrong and I only paid my deductible plus $50. He was very thorough explaining everything that he was doing and very nice since he knew I hated going to the dentist. The staff was also very nice. I will definitely be making him my new regular dentist!
