About Me

Jonathan Gilhooly, MD, knew from a young age he was called to a career in medicine. In medical school, when he saw a human brain for the first time and learned about the incredible potential within brain health and neurosurgery — his future was clinched.

Today, you can trust Dr. Gilhooly for neurosurgical care at Avera Medical Group Neurosurgery in Sioux Falls, SD.

“Caring for others in their time of need is the sacred duty of physicians and it is our responsibility to use our training, knowledge and experience to achieve the best possible outcomes,” he said.

Expert Care in Neurosurgery

Dr. Gilhooly is part of a larger brain and spine team which offers the full spectrum of surgical and nonsurgical care for disorders and conditions affecting the neurological system.

Some of the conditions he specializes in treating include:

  • Cranial and spinal tumors
  • Cranial and spinal neurotrauma
  • Degenerative spinal disease
  • Pituitary tumors and disorders
  • Trigeminal neuralgia

When your care requires neurosurgery, Dr. Gilhooly utilizes minimally invasive procedures to support a faster recovery and higher quality of outcome.

Military Experience

Before Avera, Dr. Gilhooly used his expertise during his nearly 30-year military career. One of his most rewarding experiences was caring for combat-injured military personnel post-9-11 during both Operation Iraqi Freedom and Operation Enduring Freedom.

“Military neurosurgeons are expected to have a broad surgical skillset given the variety of disorders and surgical pathology that can appear in isolated or deployed environments where access to subspecialized care may not be available,” said Dr. Gilhooly. As a result, he’s had extensive exposure in both general neurosurgery as well as specialized training.

Active Lifestyle

In his free time, Dr. Gilhooly enjoys spending time with his family, exercising, reading history, watching and participating in various sports, and traveling.
