He earned his undergraduate degree in biochemistry from the University of Wisconsin-Madison, then went on to Duke University School of Medicine for his medical degree. He also holds a master's degree in physiology and genomics. His internal medicine residency at Duke University Hospital led to his selection as Chief Resident. Before founding Carolina Longevity, he served as Chief of Clinical Informatics at the Durham VA Hospital and authored over a dozen peer-reviewed publications.
Dr. Schulteis is board-certified in internal medicine and specializes in preventive medicine, executive health, and functional medicine. His own experience navigating May-Thurner syndrome and cervical disc disease shaped his conviction that the best medicine blends prevention, optimization, and innovation. He is passionate about hormone optimization, metabolic health, GLP-1 therapies, VO2 max training, body composition, and cardiovascular risk. He believes healthspan, the years lived in strength, vitality, and independence, matters as much as lifespan.
