Dr. Daniel Thielemann, M.D., was honored to join First Coast Cardiovascular Institute in August 2011, as the medical director of the Sleep Disorders Laboratory and clinical sleep medicine services.
Dr. Thielemann was always strongly driven to academic achievement, and during his high school years in Mississippi, he was recognized as a National Merit Scholar. He subsequently graduated magna cum laude from Mississippi College with an undergraduate degree in biology, with minors in history and English. He went on to earn his Doctor of Medicine degree in 2006 from the University of Mississippi Medical Center in Jackson.
In his later years of graduate training at UMMC, Dr. Thielemann took advanced electives in neurosurgery and neuroanatomy under distinguished faculty members Andrew Parent, M.D., and Duane Haines, Ph.D., with the future goal of entering the field of endovascular surgical neuroradiology and establishing a career treating patients suffering from vascular diseases of the nervous system.
Upon graduation from medical school, Dr. Thielemann traveled to Pittsburgh, PA., to complete a one-year internship in Internal Medicine and a three-year residency in Neurology at Allegheny General Hospital. There he studied under such leaders in the field of neurological medicine as Jon Brillman, M.D., and James Valeriano, M.D., as he pursued studies in stroke medicine and vascular neurology. It was during this time frame that he first discovered and became passionate about the rapidly growing subspecialty field of sleep disorders and elected to pursue this as a career. During his last year of residency, Dr. Thielemann had the honor of being chosen as chief resident.
After selecting his new focus, Dr. Thielemann continued his training at the University of Nebraska Medical Center in Omaha, where he completed a one-year fellowship in Sleep Medicine, working under nationally recognized sleep specialist physicians Teri Barkoukis, M.D., Michael Summers, M.D., and Sabin Bista M.B.B.S.
Dr. Thielemann is an avid reader, enjoys classical music, and continues to study rich and varied subjects including mythology, art, ancient history, military history, archeology, paleontology, theology, philosophy, and the history of the state of Florida. He also enjoys salt-water fishing. Dr. Thielemann, his wife, and their two sons enjoy their family time, which includes the exploration of the greater Jacksonville and St. Augustine areas.
