Meet Our Pathologists

Our board-certified pathologists bring focused training across anatomic, clinical, and subspecialty pathology. Together, they provide the depth of expertise needed for routine diagnoses, complex cases, and collaborative consultation.

Expertise You Can Access

Pathology is most valuable when expertise is available at the moment a clinical question arises. Our physicians welcome case discussions with referring providers and work together when a specimen benefits from additional subspecialty review.
