Meet Dr. Jonathan Weissler

Holder of the:
James M. Collins Professorship in Biomedical Research

Pulmonologist Jonathan Weissler, M.D., wears many hats at UT Southwestern Medical Center – from caring for critically ill patients to serving as Chief of Medicine for UT Southwestern's University Hospitals – but he has only one goal: to provide the best care possible.

In his role as a pulmonary critical care specialist, Dr. Weissler – a Texas Monthly Super Doctor – cares for patients in the Intensive Care Unit (ICU) who have serious infections and respiratory failure.

Outside the ICU, he also sees patients with a variety of general lung problems, from chronic obstructive pulmonary disease (COPD) to pneumonia and pulmonary fibrosis.

Since he joined UT Southwestern in 1985, Dr. Weissler has seen the Medical Center grow in many ways, but especially in terms of patient care. UT Southwestern now treats many more patients and specializes in much broader areas of care.

Our goal is to make your experience at the hospital as brief, as safe, and as effective as possible."

"We've become more focused on measuring the quality of care that we deliver and on improving medical care for the patients whom we serve," he says.

Within pulmonology, Dr. Weissler says UT Southwestern's team of lung experts offers a depth of knowledge that is among the best available, and that depth attracts patients from around the country.

"We have one of the most highly regarded group of pulmonary doctors at any institution in the United States," he says.

Dr. Weissler also takes great pride in the physicians he has trained and recruited to help make UT Southwestern one of the top academic medical centers in the nation.

"I'm proud of their abilities and the fact that they are able to help people," Dr. Weissler says.
