My wife and I were patients of Dr Yalmanchili when she was with San Tan Medicial. When they merged with East Valley we continued with Dr. Yamanchili. We are very pleased with her, however, the staff at East Valley is terrible!!! They need a lot of training on customer service. The receptionists to the medical tech's are very unfriendly and seem not to care. The website says they open at 7 am M-F. When you call the recording says they open at 7:30 am, however, You get the same recording for at least 30 minutes after that time. This whole practice needs a lot of help. Although my wife and I are pleased with Dr. Yalmanchili, we are looking to go to another practice.
