Jacqueline O'Leary, M.D.
Associate Professor

Dr. Jacqueline O’Leary began her pursuit of research as an undergraduate at Stanford investigating drug development, continued at UCSF where she received an MD with thesis for work in cellular and molecular biology.  Following her internal medicine residency at UT Southwestern in Dallas, Dr. O’Leary did a GI fellowship and transplant Hepatology fellowship at Massachusetts General Hospital. Her post-doctoral research there at Harvard focused on immunology. Afterward, she completed a Master’s in Public Health from the Harvard School of Public Health. These accomplishments make her uniquely poised to translate research findings into clinical care.  

In addition to her clinical work as a transplant hepatologist, she received the Vanguard award, from the International Liver Transplant Society for her research on donor specific antibodies in liver transplantation.  She consistently earns “Best Doctors in Dallas” awards and US News & World Report Top Doctors.   Her clinical practice emphasizes personalized patient-centered care.

Dr. O’Leary’s interests outside of medicine include skiing, scuba diving, and playing tennis.
