About me

Dr. Samuel McGowan is a pulmonary and critical care specialist who cares for patients with a variety of lung conditions. He provides treatment in the intensive care unit (ICU) as well as other settings. He is medical director of the UCSF OPTIMAL Clinic, which serves patients recovering from critical illness or experiencing persistent COVID-19-related pulmonary symptoms.

McGowan's research focuses on improving the quality of ICU care and examining how critical illness affects ICU survivorship. He believes that treating patients as individuals is the foundation of providing holistic, compassionate care for all.

McGowan earned his medical degree at Rush Medical College, where he also completed a residency in internal medicine and served as chief resident. He completed a fellowship in pulmonary and critical care medicine at UCSF.

      I felt like I was really listened to and that he understood my problem. I felt like he would be good if my case had to involve him dealing with other specialists. Even though I didn't get relief, I left feeling good that I had contacted UCSF for my issue.

      Dr. McGowan listened to my concerns/questions attentively. He was very thorough in his investigation/exploration of history, possible etiology and provided clearly outlined plans.

    Please check with your health insurance plan regarding coverage for this type of care. Not all providers at UCSF Health are covered by every insurance plan.
