More About Dr. Gilligan:

Dr. Gilligan originally became interested in neurosurgery because it is both difficult and complex, and believes that having those challenges makes medicine one of the most engaging and interesting fields to practice in. He is continuously fascinated by the anatomy and the unique nature of each patient’s case.

In his free time, Dr. Gilligan stays active in sports – including basketball and tennis – which he was involved in growing up. He also enjoys cooking– taking time to explore new recipes and techniques with his wife at home.
