Joseph G. Jemsek

Dr. Joseph G. Jemsek, known to many of his patients as “Dr J.,” is the namesake and founder of the Jemsek® Specialty Clinic. Located at the heart of Washington, DC, Jemsek® Specialty Clinic provides top-quality care for those affected by Lyme and other tick-borne illnesses.

In 1983, early in his career and while at the Nalle Clinic in Charlotte, NC, Dr. Jemsek diagnosed the first case in the state of what was eventually to be recognized as HIV/AIDS. He dedicated the next two decades of his career to the care of these severely ill and marginalized patients.

In 2000, he founded the Jemsek® Clinic to provide primary care to the HIV/AIDS community. This practice was recognized as the largest provider of HIV/AIDS care between New York and Miami. Dr. Jemsek also has a strong affinity for philanthropic work, and in 2003 created the Jemsek® CHARM project, which was a 501c(3) organization devoted to the care of the HIV/AIDS community. In 2009, he was awarded the North Carolina Certificate of Appreciation for his work. This is the highest civilian award offered in the state, bestowed solely on a merit basis.

In 2001, quite by chance, he gradually began to see patients at the Jemsek® Clinic suffering from what would later be termed Lyme Borreliosis Complex. Dr. Jemsek became increasingly intrigued by LBC’s complexities which led to his full dedication towards understanding and treating these often-marginalized patients. This dedication led to the eventual establishment of the Jemsek® Specialty Clinic in Washington, DC, which proudly serves patients from every U.S. state and over a dozen countries.

As an infectious disease specialist, Dr. Jemsek has the distinction of being a key player in the twin epidemics of modern times, HIV/AIDS and Lyme Borreliosis Complex.
