High quality slides are produced using the latest equipment from Leica and Milestone. We were the first installation of the Leica Spectra Stainer in Colorado with precision agitation to ensure even reagent distribution. Our Leica Bond Max allows for precise and timely immunohistochemistry (IHC) staining as well as multi-plexing of antibody combinations. All special stains and IHC antibody staining has been validated and verified independently for exceptional quality.


Dr. De Stefano is a pathology-trained dermatopathologist who believes that specialized specimen preparation, careful biopsy examination, and constant communication between dermatologists and dermatopathologists are essential to achieve excellence in patient care. She feels truly fortunate to be part of a wonderful multidisciplinary team at her practice.

Dr. De Stefano is board-certified in Anatomic Pathology by the American Board of Pathology, and in Dermatopathology by the American Board of Dermatology and the American Board of Pathology.  The mission of these boards is to serve the public and advance the profession of pathology, dermatopathology, and dermatology by setting certification standards and promoting lifelong competency of pathologists.

Dr. De Stefano received her medical degree in Brazil. She then went on to complete her residency at the Department of Pathology of the Stanford University School of Medicine, one of the leading institutions in the country. Furthering her training, she completed her dermatopathology fellowship at University of Texas Southwestern Medical Center in combination with Cockerell Dermatopathology in Dallas, Texas.

Dr. De Stefano is a member of the American Society of Dermatopathology and the College of American Pathologists. She attributes her success to her love for learning about skin diseases and uses the knowledge she gains to help her patients.

Dermatopathology, is a joint subspecialty of dermatology and pathology that focuses on the study of cutaneous diseases at a microscopic and molecular level. A dermatopathologist, like Dr. De Stefano, is a highly trained physician who specializes in diagnosing disorders of the skin, hair, and nails under a microscope. When a skin biopsy is needed, doctors specialized in dermatopathology work closely with dermatology providers to narrow down the potential causes of skin disorders, such as a rash, alopecia, or to determine the malignant potential of a tumor. With that information, dermatology providers can determine the best treatment approach for their patient.  

Dr. De Stefano was born and raised in Brazil but has spent here last 15 years in the United States and the last 2 years in Colorado, the state she quickly learned to call it home. In her spare time, she enjoys spending time with her family and her 3 dogs, exploring all that the Rocky Mountains have to offer. She also enjoys pencil drawing, painting, and gardening.
