Dr. Johnson is a Board-certified neurosurgeon who specializes in minimally invasive and complex spinal surgery and cranial surgery for brain tumors.

He has been practicing in the Central Valley since 2011. Dr. Johnson most recently served as an Associate Clinical Professor and the founding Chief of the Department of Neurological Surgery at University of California, San Francisco-Fresno.

He completed his neurosurgery training at Brigham and Women’s Hospital, Harvard Medical School, after which he completed two fellowships, the first in Complex Spine Surgery at the Boston Spine Group/Tufts University, and the second in Minimally Invasive Spine Surgery at the Spine Clinic of Los Angeles/Good Samaritan Hospital. Dr. Johnson earned his medical degree from the University of Louisville School of Medicine in Louisville, Kentucky, and his bachelor’s degree in Nursing from the University of Virginia School of Nursing in Charlottesville, Virginia.

“My interest in medicine sparked in high school when my twin nieces were born prematurely,” he says. “As I grew older, I also developed a desire and an interest in treating and helping individuals with brain and spine disorders.”

During his free time, Dr. Johnson enjoys running, fitness, traveling and cars.
