About PhenoPath

PhenoPath was founded in 1998. Since its inception, PhenoPath has been pathologist-driven. Our primary principle has never wavered: making correct diagnoses (“Diagnoses you can count on®”) through the best practice of pathology.

Dedication to excellence is in our DNA, and is reflected in every pathology report we issue. Our commitment is evident in the high level of training and expertise of our pathologists and staff, the publications of our pathologists in journals and books, and our pathologists’ participation as invited experts at national meetings. You can be assured that when you phone for information and need to speak with a pathologist, one will be available to consult with you.
