Dr. Mistretta works closely with a team of APCs (Advanced Practice Clinicians). These APCs train with Dr. Mistretta and work under his supervision to ensure that all patients receive timely high-quality care. Dr. Mistretta spends half of his time working in the hospital and so he is not always available in the office, but one of his APCs will be available to take care of you.
