Pathology Group of the MidSouth, PC has provided superior medical diagnostic services since 1947. Our physicians are Board Certified in the broad spectrum of pathology subspecialties and render interpretative, diagnostic and consultative services for medical colleagues throughout the region.


Dr. Merlin L. Trumbull, our founder, was trusted by his peers for accurate and timely diagnoses and was widely regarded as the quintessential doctor’s doctor. That tradition of trust continues as PGM partners with Trumbull Laboratories, LLC to deliver reliable, comprehensive, efficient and personalized service every day.


Trumbull Labs supports PGM through its uniquely educated and expertly trained staff experienced in the following disciplines: cytotechnology, histotechnology, flow cytometry, pathologist assistant, transcription, sales, client services, couriers, billing, information technology and administration.


Trumbull Labs and PGM know that each specimen represents an anxious patient and concerned clinician awaiting critical diagnostic information – information that must be accurate, timely and confidential. Consistent delivery on each of these vital functions enables the implementation of effective and efficient treatment protocols and facilitates the tradition of trust on which we were founded.
