The pathologists at Marshall Health work collaboratively with other clinicians at Marshall Health and at area hospitals including Cabell Huntington Hospital, St. Mary’s Medical Center and Rivers Health. The pathologists evaluate blood/body fluid samples and microscopic tissues to determine whether disease processes exist and, with your doctor, determine the best course of treatment.

In addition to many years of general anatomic and clinical pathology practice, our team of pathologists have specialized training and experience in the following areas: 

  • Anatomic pathology
  • Clinical pathology
  • Cytopathology
  • Dermatopathology
  • Hematopathology
  • Oncologic surgical pathology
  • Pulmonary pathology
  • Surgical pathology
  • Transfusion medicine
