About me
Bergen Kassoff, PA-C, is a nationally certified physician assistant at MedStar Washington Hospital Center and MedStar Health Medical Center at Mitchellville. She specializes in gastroenterology and closely collaborates with Dr. Danny Shearer, Dr. Gary Thompson, Dr. Lauren George and Dr. Arthur West. She is an active member of the American College of Gastroenterology and the American Academy of Physician Associates.
Ms. Kassoff is skilled in diagnosing and treating a wide range of gastrointestinal conditions, including but not limited to gastroesophageal reflux disease (GERD), esophagitis, gastritis, H. pylori infection, peptic ulcer disease, pancreaticobiliary disorders, irritable bowel syndrome (IBS), and colitis. Additionally, she is deeply committed to cancer prevention and regularly conducts preprocedural visits for colorectal cancer screenings. Her comprehensive approach to care includes lifestyle modifications, medication management, and other therapeutic interventions.
A native of the DMV, Ms. Kassoff began her medical career as a volunteer emergency medical technician (EMT) at the Bethesda-Chevy Chase Rescue Squad. She went on to Pennsylvania and graduated with highest honors from Lehigh University, obtaining a Bachelor of Arts in behavioral neuroscience. After her undergraduate studies, she worked in clinical research at Children’s National Hospital. Although passionate about research, Ms. Kassoff wanted to have direct involvement in patient care, so she decided to get her Master of Science in physician assistant studies at Philadelphia College of Osteopathic Medicine (PCOM). Ms. Kassoff is honored to be back home serving the community that raised her.
Philosophy of Care
"My approach to healthcare is centered on a patient-first philosophy, emphasizing compassionate, holistic care tailored to each individual's unique needs. I want my patients to know that I am their advocate and will strive to help them reach their health goals. I believe in the importance of patient education and empowerment, ensuring that those under my care are fully informed and active participants in their treatment plans.”
