Trusted Pathology Partners

Board-certified, academic, collaborative pathologists. We work with dermatologists and oral providers to diagnose skin, hair, nail and oral biopsies. If you received a bill from CTA Pathology, your provider sent us a specimen and requested we work with them to diagnose the tissue.
Digital Healthcare Pioneers

Pathologists work closely with in-house histotechnologists to produce brilliant glass slides and digital slide images. As the first fully-digital dermatopathology lab in the US, we are committed to advancing healthcare technology as a tool for integrative patient care.
Integrative Patient Care

Physician-owned and operated, we understand the critical role a diagnosis plays in your patients’ treatment plans. Exceptional patient care is at the core of our company mission. Each member of every department at CTA has been hand selected to deliver this mission.
Histology Laboratory Leaders

Laboratory staff and high-complexity technicians at CTA are qualified and credentialed. Special stains, tests and IHCs are validated alongside a pathologist to ensure brilliant slide quality and preserve specimen integrity–from hematoxylin & eosin to direct immunofluorescence (DIF) and more.
