Dr. Johnson earned his undergraduate and medical degrees from the University of Pennsylvania with a concentration in Neuroscience, graduating Summa Cum Laude with Phi Beta Kappa Honors. He completed a residency in neurosurgery at the University of Pittsburgh Medical Center. During his time in Pittsburgh, Dr. Johnson also completed a fellowship in stereotactic neurosurgery under the mentorship of Dade Lunsford, a world-renowned pioneer in Gamma Knife Radiosurgery. His training also focused on microvascular decompression surgery under the guidance of Raymond Sekula, a renowned surgeon in the lineage of Peter Jannetta, who initially pioneered the procedure.

Dr. Johnson specializes in Gamma Knife Radiosurgery, cranial nerve disorders, and spinal neurosurgery and has published both peer-reviewed articles and textbook chapters in these areas. He utilizes both incisionless Gamma Knife Radiosurgery and traditional open approaches in the management of cranial pathology. Similarly, he offers both minimally invasive and open treatments for degenerative spine diseases. This multi-modal approach enables Dr. Johnson to provide highly customized and effective treatment for each individual patient.

Dr. Johnson has a research focus on clinical outcomes after radiosurgery. He sees patients with all spinal conditions, brain tumors, and cranial nerve disorders. Currently, he treats patients at Robert Wood Johnson University Hospital and Community Hospital.

A New Jersey native, Dr. Johnson enjoys surf fishing, Italian dining, and traveling with his family.
