Internist and Rare Disease specialist Marjorie Dejoie-Brewer, MD, Champions Wellness & Advocacy for Sickle Cell Patients
Renowned Clinician, Researcher, and Patient-Leader Offering Integrative Care and Community Impact through MAD Fit Wellness
Dr. Marjorie Dejoie-Brewer, MD, a distinguished Internist-Physiatrist with a focus on blood disorders and a proud patient of sickle cell disease herself, is bringing her decades of medical expertise and deeply personal advocacy to Camden, New Jersey, and globally, through her holistic consulting practice, MAD Fit. As a nationally recognized medical director, clinician, and wellness entrepreneur, Dr. Dejoie‑Brewer provides comprehensive, integrative care—blending traditional medicine with lifestyle & preventative medicine, patient empowerment, and community engagement.
Diagnosed during her second year at the University of Pennsylvania School of Medicine, Dr. Dejoie‑Brewer transformed a personal health challenge into a powerful catalyst for change. She pursued a career in internal medicine and rehabilitation, guided by a mission: to equip patients living with sickle cell and rare diseases with practical tools for resilience, self-care, and long-term well-being. Her journey embodies the mission of her work—she knows firsthand that “you are not your disease” and champions patient-minded, evidence-informed care.
Dr. Dejoie‑Brewer’s multifaceted leadership spans roles including Director of Patient Strategy & Advocacy at Fulcrum Therapeutics, Medical Director of the Sickle Cell Disease Association of Delaware, Global Medical Director at Vertex Pharmaceuticals, Research Clinician at Children’s Hospital of Philadelphia, and Patient Engagement Lead in rare disease initiatives at Pfizer. A pioneer in functional and integrative medicine, she founded MAD Fit in 2002. She later opened the wellness center Bonne Santé, merging clinical rigor with holistic care—nutrition, prescribed exercise, stress reduction, and complementary therapies—specifically tailored for people with rare conditions. Dr. Dejoie‑Brewer, part of Vertex’s Global Medical Affairs team, played a pivotal role in bringing forward the first gene therapy for sickle cell disease
Her advocacy extends far beyond clinical walls. Dr. Dejoie‑Brewer has collaborated with institutions such as the American Red Cross, EveryLife Foundation, Global Genes, PCORI, American Heart Association, Susan G. Komen, Lupus Foundation, NIH, NHGRI, SCCC, and SCDAA, emphasizing community-engaged outreach, improving access, reducing stigma, and enhancing patient trust. As a passionate advocate for blood donation, she elevates awareness around the critical need for matched blood in the sickle cell community and regularly helps organize and actualize blood drives in her area, and she is a recipient of blood donations through her monthly apheresis treatments.
Now serving patients in Camden, NJ, and the surrounding area, through MAD Fit, Dr. Dejoie‑Brewer invites those living with sickle cell and other blood disorders to experience integrative, personalized care, where patients’ voices are heard, support is ongoing, and wellness is redefined collaboratively. Through her consulting, she continues to bridge the gap between clinical science and patient-centered compassion, empowering individuals to thrive beyond their diagnosis.
