About Me

Dr. Thal earned her Bachelor of Science from The Schreyer Honors College at Penn State University. She earned her M.D. at The Penn State College of Medicine and completed her residency at the Penn State Health Family and Community Medicine Residency at Mount Nittany Medical Center. During her residency, Dr. Thal served as Chief Resident and she also received a certificate of appreciation from the Penn State Navy and ROTC programs, recognizing her work during the COVID-19 pandemic.

“Working at Mount Nittany Health enables me to become my hometown’s family doctor,” said Dr. Thal. “I was born at Mount Nittany Medical Center and trained with the physician who delivered me.”

In addition to her family medicine duties, Dr. Thal is certified in advanced headache diagnosis and management from Thomas Jefferson University and works in the Mount Nittany Physician Group Neurology Clinic two days a week. She is a member of the American Academy of Family Physicians and the Pennsylvania Medical Society.

    Dr. Karissa Thal was absolutely amazing. She was very empathetic, took the time to truly listen to my concerns, and made me feel heard and respected throughout the entire appointment. I never felt rushed, and she explained everything clearly and thoughtfully. Her compassion and professionalism made a big difference in my experience, and I am very grateful for the care she provided.

    I had an unpleasant experience with Dr. Thal yesterday. She is not very personable, and she is very pushy when it comes to exercise.
