Practice Coordinator Tammy Vargas-Maionchi works with patients from the first consultation appointment with Dr. Swiersz through their entire treatment process in reproductive endocrinology and fertility. She provides new patients information on what to expect at the first appointment and will answer any questions about available services.

Tammy also works with patients to verify which infertility treatments and medications their health insurer will cover and what patients may expect to pay out-of-pocket. In addition, Tammy schedules appointments, coordinates Dr. Swiersz's schedule and manages the daily activity of Reproductive Endocrinology and Fertility.
