Meet the Providers

Our providers utilize a holistic approach to pulmonary care. We evaluate each patient on an individual basis to identify any and all conditions that may be affecting the patient's respiratory well-being.

To provide the best care for our patients, Lung & Sleep Specialists of North Texas employs advanced practice providers who may participate in your care. Both nurse practitioners (NP) and physician assistants (PA) have advanced clinical training and a master’s degree; some also have a doctoral degree.

NPs and PAs are qualified to perform physical exams, order and interpret laboratory and test results, create treatment plans, make referrals, and prescribe medications. They provide urgent and routine care for our patients in the office setting. Our team of advanced providers works closely with our doctors to optimize patient outcomes and overall satisfaction.
