Meet Dr. Lai

Primary Care Physician in Dallas

Wen Lai, M.D., is a primary care physician practicing at the UT Southwestern Clinical Center at Las Colinas. As a general internist, Dr. Lai forges lasting relationships with her patients and works hard to help them maintain and improve their overall health.  

“I think one of the important roles of a primary care doctor is to help direct people in their medical journey,” Dr. Lai says.

She also helps patients manage chronic disorders such as high blood pressure, diabetes, thyroid disorders, and heart disease. She is often the first doctor her patients see when they have developed serious or life-threatening conditions, such as cancer or organ failure, and she is able to refer her patients to the right medical specialist to receive treatment for that condition. 

Dr. Lai believes the key to providing good primary care is attentiveness and compassion. She approaches each diagnosis and treatment plan carefully to guarantee the best possible outcome for each individual patient.
