Katrina Firlik grew up in Shaker Heights, Ohio, and graduated from Shaker Heights High School. She then attended Cornell University where she majored in cultural anthropology. She returned back home to Cleveland for medical school at Case Western Reserve University.

Katrina was the first woman admitted to the neurosurgery residency program at the University of Pittsburgh Medical Center, one of the largest and most prestigious programs in the country. She then spent six years as a neurosurgeon in private practice in Greenwich, Connecticut and served on the clinical faculty at Yale University School of Medicine.

Katrina currently focuses on medical innovation as an entrepreneur. She is a founder and the chief medical officer of HealthPrize Technologies. HealthPrize is developing a novel solution to a serious problem in healthcare: poor compliance with prescription medications, a problem that often leads to poor clinical outcomes and is the source of an estimated $290 billion per year in preventable healthcare spending.

Katrina lives in Darien, Connecticut, with her husband Andrew, a neurosurgeon turned venture capitalist, and their daughter, Annika. Another Day in the Frontal Lobe is her first book.
