GLEN BURNIE, Md. (Sept. 2, 2025) — The University of Maryland Baltimore Washington Medical Center (UM BWMC), a member organization of the University of Maryland Medical System (UMMS), has appointed Jeffrey Marshall, MD, MPH, as Vice President and Associate Chief Medical Officer.
In this leadership role, Dr. Marshall will oversee key areas across both the hospital and ambulatory care settings, including quality, safety, infection prevention, regulatory compliance and accreditation, care management and ethics. He will also be involved in the University of Maryland Baltimore Washington Medical Group’s operations, a multi-specialty network comprised of more than 300 employed physicians and advanced practice providers.
Dr. Marshall will work closely with Jason Heavner, MD, UM BWMC’s Senior Vice President and Chief Medical Officer, to continue advancing research and academic medicine in a community hospital setting, ensuring residents of Anne Arundel County and the surrounding region have greater access to expert care, cutting-edge clinical trials and the latest medical innovations, in partnership with UMMS and the University of Maryland School of Medicine.
“Dr. Marshall is a proven leader with a deep commitment to excellence in clinical care, innovation and community health,” said Kathy McCollum, President of UM BWMC. “His continued leadership will be essential as we expand access to high-quality care and bring more advanced treatments and clinical research opportunities to people in Anne Arundel County and across Maryland.”
An expert in pulmonary and critical care medicine and research, Dr. Marshall has been with UM BWMC since 2018 where he has held several key leadership positions, including Associate Chair of Medicine, Chair of Pulmonary and Critical Care, Medical Director of Respiratory Therapy and Chair of the Ethics Committee. During his tenure, Dr. Marshall has led numerous impactful initiatives, including:
- Opening the new critical care unit and expanding the clinical team to support its growth.
- Launching the hospital’s robotic bronchoscopy program, providing a safer and more precise method for the early diagnosis of lung cancer. The program has rapidly grown to become the busiest in Maryland, surpassing 500 cases this summer.
- Working with the cardiology and pulmonary teams to open adjacent practices in UM BWMC’s Outpatient Care Center, nearly tripling the number of exam rooms and better aligning care for heart and lung patients.
- Expanding pulmonary care offerings, including creating the pulmonary hypertension program, adding cardiopulmonary exercise testing services and growing pulmonary function testing capabilities.
- Collaborating with interventional cardiology and vascular services to introduce a pulmonary embolism thrombectomy program in the hospital’s procedural suite.
“Dr. Marshall brings a unique blend of clinical expertise, visionary leadership and a deep commitment to collaboration,” said Dr. Heavner. “His ability to integrate the latest clinical advances with thoughtful, multidisciplinary planning has directly improved the care we provide to some of our most critically ill patients. At the same time, his work has strengthened our outpatient programs, helping patients with chronic conditions better manage their health at home and in their communities. His leadership continues to drive innovation across our health system and expand access to high-quality care.”
Dr. Marshall is also an active investigator leading clinical trials that evaluate the effectiveness of bedside interventions for critical care patients and explore how artificial intelligence can detect smaller lung nodules and improve earlier detection of lung cancer. Initial success with the lung nodule trial led the project to expand from the Emergency Department to areas of UM BWMC’s inpatient and outpatient care settings.
“It’s an honor to continue serving the residents of Anne Arundel County and my fellow colleagues in this new capacity,” said Dr. Marshall. “I’m grateful for the mentorship and trust I’ve received from UM BWMC’s leadership, and I’m excited to build on the strong foundation of care our team has established. This role is a chance to shape the future of care in our community, delivering compassionate, evidence-based medicine while continuing to expand access to clinical research and the benefits of academic medicine. I’m humbled by the opportunity, and excited to get it right for the people we care for and serve.”
Dr. Marshall earned both his medical degree and Master of Public Health from the Mount Sinai School of Medicine. He completed his internal medicine residency at the Cambridge Health Alliance affiliated with Harvard Medical School and his fellowship in pulmonary and critical care medicine at Yale University. He also holds a Master of Science in Biomedical Ethics from Albany Medical College and completed a fellowship in bioethics at Oxford University. He is a graduate of the UMMS Physician Leadership Fellows Program and currently serves in multiple system-wide leadership roles, including Chair of the UMMS Lab Stewardship Committee and the Organ Procurement Governance Committee.
