Gastrointestinal
& Liver Pathology

We Prioritize Diagnostic Accuracy

Our GI pathology service is led by fellowship-trained pathologists who have trained under and practiced alongside some of the most respected names in gastrointestinal pathology. Their collective experience spans academic medical centers, national reference laboratories, and high-volume private GI practices.

This diverse background equips our team to confidently diagnose a broad spectrum of GI and liver pathology, from routine biopsies to complex inflammatory, neoplastic, and hepatobiliary conditions.

We prioritize diagnostic accuracy and collaborative review. Every case of dysplasia is automatically reviewed by a second pathologist, and our team routinely shares cases internally for second opinions—without delays or the need for external referral. Our clients benefit from both subspecialty depth and real-time access to expert consultation, all within a single practice.
