Louisa S. Ziglar, MD, FACR

Dr. Ziglar is a graduate of Stony Brook University where she was a scholar member of the Phi Beta Kappa honor society. She earned her medical degree at the State University of New York, Downstate, and completed her internal medicine residency at North Shore University Hospital, New York. She completed her fellowship training for rheumatology at New York University’s  Hospital for Joint Diseases, where she was recognized by medical residents with the Fellow of the Year Award for distinguished teaching. 

Following fellowship, Dr. Ziglar began private practice while she maintained teaching faculty appointments as Assistant Clinical Professor of Medicine at  Montefiore Medical Center in New York and later at St. Joseph Regional Medical  Center in New Jersey. In 2015, she moved to the Washington, DC suburbs to join a large multi-specialty practice where she quickly gained recognition as a  Washingtonian Top Doctor as well as Bethesda Magazine Top Doctor. 

Although Dr. Ziglar treats all types of rheumatic conditions, she has a special interest in osteoporosis and has conducted lab research focused on promoting the development of bone and cartilage cells. Her research was recognized in the form of awards and scholarships through the National Science Foundation, the  National Institutes for Health, and the Howard Hughes Medical Institute. She has contributed to the Journal of Biological Chemistry and her research was presented in multiple national abstract meetings.  

When not in the office, Dr. Ziglar finds meaningful time through involvement in healthcare advocacy. While a member of the American College of  Rheumatology’s Government Affairs Committee, she led the 2019-2022 revisions of the College’s Health Policy Statements. She currently serves as a member of the American College of Rheumatology’s Committee on Rheumatologic Care. 

Dr. Ziglar is board certified in rheumatology, clinical densitometry and is a fellow of the American College of Rheumatology. She lives with her husband and two very active boys. Dr. Ziglar is accepting new patients at both our Rockville and  Frederick office locations. The minimum age accepted is 17 years.

“Dr. Ziglar was wonderful, empathetic and I am so glad I got to see her. She answered my questions and never made me feel rushed. She even wrote things down for me. I especially appreciate that she listened to me.”

“Dr. Ziglar I have never felt more appreciated and concerned for from a doctor’s office before. I felt welcomed and understood. I love this office and will definitely recommend to others. Thank you for all that you do.”
