• The Valley Heart Providers

Welcome to Valley Heart Associates

Valley Heart Associates is an independent cardiology practice founded in February 2011, by Daniel F. Klee, M.D. and Jon E. Stevenson, M.D, joined by Estela Apolinar, M.D. in 2014. We are a group of medical practitioners who specialize in the diagnosis and management of patients with cardiovascular conditions, including ischemic heart disease, acute myocardial infarction, congestive heart failure, arrhythmias, valvular heart disease, lipid disorders, and peripheral vascular disease.

One of our primary goals is preventive cardiology; to prevent or mitigate known risk factors for heart disease, such as diabetes, smoking, obesity, high cholesterol, and high blood pressure. We emphasize outstanding clinical care, humanism, compassion for patients and their families, and clarity of communication.

We at Valley Heart Associates are committed to providing each patient with an exceptional level of health services. Our dedicated physicians and staff work together as a team to provide high quality, comprehensive cardiac care, and take pride in giving personalized attention based on individual patients’ needs.

Our physicians are board certified in Cardiology and Nuclear Cardiology. Drs. Klee and Stevenson are also board certified in Interventional Cardiology. We are on staff at the following hospitals:

  • Chandler Regional Medical Center
  • Mercy Gilbert Medical Center
  • Banner Desert Medical Center
