About Me

A young Randy Bell was training in the neurosurgery operating room when the Twin Towers fell. It was in that moment he knew he was called to be a military neurosurgeon.

Today, Randy Bell, MD, brings his vast expertise in interventional radioneurosurgery and cerebral vascular surgery to Avera Medical Group Neurosurgery Sioux Falls in Sioux Falls, SD.

  • Cerebral aneurysm
  • Cerebral vascular malformations
  • Stroke
  • Spontaneous intercranial hemorrhage
  • Tumors of the brain, pituitary gland, spine or other structures
  • Facial pain and spasm
  • Degenerative spine conditions

Leader in Traumatic Brain Injury and Research

Dr. Bell is considered one of the world’s leaders in neurotrauma, or traumatic brain injury. His experience as a military neurosurgeon, including a battlefield deployment and several overseas assignments, formed the foundation for his expertise in severe traumatic brain and cerebrovascular injury.

His passion for patient care and research have resulted in millions of dollars of grant-sponsored research focused on improving care to the most severely brain injured patients. He has authored or co-authored over 60 peer reviewed publications that can be found at google scholar.

Active Lifestyle

Dr. Bell is thankful he serves in a region that feels like home. His hobbies include spending time with his family. With four children, he and his wife are very busy either going to school events or doing outdoor activities together.

“Watching them grow and participate in their passions is when I have the most fun,” he said.

If he has time for personal interests, Dr. Bell likes to bike, fly fish and golf.
