Dr. Louis SloanIn Memory of Our Founder Dr. Louis Sloan

Dr. Louis Sloan joined North Texas Infectious Diseases Consultants in 1994 and unfortunately left us when he lost his battle with lymphoma in 2017. He became a partner in the practice in 2000 and the sole owner in 2007 when he implemented all the changes that have occurred over the years. He developed a clinical research program for HIV/AIDS, a specialty retail pharmacy to help his HIV patients get their medications, expanded the infusion center to include a satellite office and a 17 chair infusion center at our downtown location, and grew the practice to include 7 providers and a staff of over 60 employees. > Read more about Dr. Sloan
