Maly Fenelus, MD, MPH
Pathologist
My Role at MSKWe post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.
About Me
- Assistant Director, Clinical Hematology Laboratories
- Director, MSK Nassau Clinical Laboratory
I am a physician who specializes in performing and interpreting laboratory tests on blood and other body fluids. I collaborate with healthcare professionals to provide diagnostic and management plans that are tailored to each patient. Making precise diagnoses requires the synthesis of observations made at the microscope with interpretations of laboratory values in the context of each patient’s clinical condition. This diagnostic process is critical for diagnosing cancer, guiding treatment decisions, and monitoring interventional outcomes.
As Medical Director of our clinical laboratories at MSK Commack and MSK Nassau I help bring the quality of MSK laboratory medicine to Long Island. My expertise is in laboratory hematology and hemostasis. Additionally, I have a special interest in developing clinical decision-making tools to facilitate diagnosing and monitoring our patients. Alongside my clinical laboratory colleagues, I ensure laboratory tests are accurate and provide meaningful information for patients and clinicians.
A pathologist is a doctor who uses a microscope to make a diagnosis from cell and tissue samples. They analyze the samples to learn the cause and effects of a health condition.
