I have been a patient at Parkway since I relocated to Arizona from Illinois in 2008. I elected Dr. Bierman as my physician without really knowing anything about him and I can honestly say my luck stayed with me. Dr. Bierman is never too busy to answer any and all questions, is very concerned about the patient's well-being, and I usually never have to wait in the waiting room more than 20 minutes. The office is always clean, well-staffed, and all employees are friendly. Great Place!! great Doctors!
