About Clin-Path Associates


Clin-Path Associates, PLC, is the largest physician owned pathology practice in the state of Arizona.  The pathology group practice is composed of 27 Board Certified physicians, 7 certified pathologists’ assistants and a Ph.D.  The Group was incorporated in 1974, under the direction of Larry D. Shaw, M.D. and Louis A. Rosati, M.D. Since that time, the company has grown to serve a variety of hospitals, clinics, doctor’s office, laboratories and other facilities.

The Group’s depth of expertise is unmatched in the State and includes several speciality divisions:

  • Dermatopathology: The division is staffed by five sub-specialty Board Certified Dermatopathologists. The focus of this service is to provide expertise in the diagnosis of diseases of the skin. This service is provided to hospitals, ambulatory surgery centers and physician office practices.  A key component of this service is our consensus approach to complex cases and the ability to support some diagnoses with on site direct immunofluorescence testing.
  • Cytopathology: This service utilizes seven Board Certified Cytopathologists to diagnose Pap smears, body fluids, CT guided fine needle biopsies, aspirate smears and brushings. A fine needle biopsy service is provided by the Group at Banner Desert Medical Center.
  • Hematopathology: The department is staffed by four Board Certified Hematopathologists who work with oncologists in the community to provide diagnostic services related to diseases in the blood, bone marrow and lymph nodes.  As part of our service to physicians, we provide a bone marrow collection service at various locations.  This service optimizes specimen collection while affording the patient a comfortable and pain free surgical environment.  Diagostically, we support our pathology service with a large immunohistochemical library as well as flow cytometry and fluorescent in-situ hybridization (FISH) laboratory.  Our integrated reports incorporate cytogenetics, flow cytometry, pathology and FISH determinations into a single and easy to read report.  Our diagnostic expertise results in over 2000 challenging oncological cases being referrred to us per year.
  • Pediatric Pathology: Our Group is fortunate to have a Fellowship Trained Pediatric Pathologist on staff available to diagnose and consult on all biopsies and surgical specimens obtained from children.

Clin-Path Associates, PLC, is one of five pathology groups that form Pathology Specialists of Arizona, LLP.  This alliance is instrumental in providing medical direction for the integrated laboratories of Banner Health Systems of Arizona and its commercial laboratory, Sonora Quest Laboratories.  Our expertise as laboratory medical directors provides contacted clients with a significant opportunity for reduction in laboratory expenses by consolidation, standardization, improved productivity and efficiency.
