Welcome to the Outpatient Cytopathology Center (OCC). We are an independent medical practice dedicated for performance and interpretation of ultrasound guided fine needle aspiration biopsies (FNA). We also provide diagnostic ultrasound scan evaluation for thyroid, parathyroid, salivary gland and cervical lymph node mapping.

Our clinic was established in 1991, one of the first in the United States. The physicians and staff at OCC are dedicated to providing patients quality service in a timely and cost effective manner. We offer 24-hour turnaround time with accurate reliable results to our providers.

FNAs are performed and interpreted by our three board-certified physicians:

  • Susan Rollins, MD, FCAP, FIAC
  • Janet Stastny, DO, FCAP
  • Yasmin Elshenawy, MD, FCAP, ECNU
