Dr. BaldwinZach Baldwin, M.D., FACS
School: University of Chicago Pritzker School
of Medicine
Fellowship: University of California, San Francisco
Specialty: Endovascular and Vascular Surgery

Personal Interests: Dr. Baldwin, a native Californian, grew up the son of an emergency room physician in the San Francisco Bay Area. After graduating high school, he attended college at the University of California at Davis. There he double-majored in Classical Civilization and Physiology. After finishing college Dr. Baldwin took a three-year hiatus from studies to move to the Sierra Nevada mountains where he worked as a blackjack dealer and ski instructor.

However, his goal of following in his father’s footsteps and attending medical school remained a priority. He ultimately attended and graduated from the University of Chicago Pritzker School of Medicine. While there, he began researching carotid artery atherosclerosis which ultimately led to an interest in vascular biology and disease. During surgical residency, he returned to the University of Chicago where he undertook a research fellowship focusing on biologic therapies used to inhibit blood vessel scarring after vascular and endovascular surgery. This research culminated in several publications and the Society for Vascular Surgery Lifeline Foundation Research Prize.

Dr. Baldwin went on to finish his general surgery residency and, subsequently, vascular fellowship at the University of California, San Francisco. He is board certified in both vascular and general surgery and is a Fellow of the American College of Surgeons. He is active in numerous regional and national vascular societies as both a speaker and officer.

Dr. Baldwin is author of over 20 peer- reviewed articles and has served as primary investigator for multiple global studies involving complex aortic disease and peripheral vascular disease. His clinical interests include the use of minimally invasive catheter-based (endovascular) therapy for treatment of vascular disease including aortic aneurysm, diabetic peripheral vascular disease and dialysis access. Dr. Baldwin is currently the only physician in Mississippi certified to perform fenestrated repair of complex aortic aneurysms (FEVAR). Through a combination of innovative technology and durable intervention, he is able to offer patients procedures which minimize risk and allow for a quick and uncomplicated recovery.

Dr. Baldwin relocated south with his wife of 11 years, Laurie, in order to be closer to her Louisiana “kin folk.” They have lived in Madison, Mississippi for the past 6 years with their two children.

School: Baylor College of Medicine, Houston TX
Fellowship: Baylor University Medical Center
Specialty: Endovascular and Vascular Surgery

Personal Interests: Dr. Cumbie was born and raised on the Texas Gulf Coast where he completed high school before attending Baylor University in Waco, Texas. He received his Bachelor of Science in Chemistry, Summa Cum Laude from Baylor. He then returned to the Houston Area to attend Baylor College of Medicine where he obtained his medical degree. After medical school, Dr. Cumbie completed his general surgery training at the University of Texas Southwestern and Parkland Memorial Hospital. He then did a two year peripheral vascular and endovascular surgery fellowship at Baylor University Medical Center in Dallas. Dr. Cumbie is board certified by the American Board of Surgery in General Surgery and Vascular Surgery. He also holds a certification for vascular ultrasound interpretation by the American Registry for Diagnostic Medical Sonography.

Dr. Cumbie was drawn to a career in vascular surgery during his time as a general surgery resident in Dallas. Here he was able to train under several world renowned vascular surgeons on the most up-to-date minimally invasive endovascular techniques. During his training, he was active in research and has since collaborated on several research projects and publications in the fields of vascular trauma, carotid artery stenting, and minimally invasive endovascular aneurysm repair. He is the winner of several awards including the Raleigh Ross Scholar award presented to the top surgery resident by the Texas Surgical Society. He is also a member of the Society of Vascular Surgery. His professional interests include carotid artery disease, aortic aneurysms, and open and endovascular (minimally invasive) limb salvage procedures for peripheral arterial disease.

Despite the time demands as a vascular surgeon, Dr. Cumbie is a devoted husband to his wife Caroline, and father to his two young children. He is also very active in his church community and has been on several medical mission trips to rural areas in Honduras to provide medical care and participate in public health initiatives. In his free time, Dr. Cumbie loves to spend time doing outdoor activities such as waterskiing or hunting.

He completed his general surgery internship, residency and research fellowship at Tulane School of Medicine, where he participated actively in various experimental and clinical research projects. His thoracic and cardiovascular surgery residency was completed at the Carolinas Heart Institute (Sanger Clinic) in Charlotte, North Carolina. Dr. Keller is Board Certified in Cardiovascular and Thoracic Surgery.

An author or a co-author of more than 40 scholarly publications, presentations, book chapters and abstracts, Dr. Keller is intimately aware of and involved in the application and development of cutting edge technology, and dedicated to providing access to the best that medicine has to offer for his patients.
