Randall R. Johnson, MD, PhD, FACS

Dr. Randall Johnson, MD, PhD, FACS, is a board-certified neurosurgeon at Neuroscience Group and one of the most academically credentialed physicians in the practice. He earned his Bachelor of Arts from Northwestern University before completing both his Doctor of Medicine and his Doctor of Philosophy at Washington University in St. Louis, which is consistently ranked among the top medical research institutions in the United States. He completed his surgical internship and neurosurgery residency at Yale-New Haven Hospital, followed by specialized training at Barrow Neurological Institute and advanced coursework in skull base surgery, minimally invasive spine techniques, and cervical and lumbar disc replacement. Dr. Johnson is a Fellow of the American College of Surgeons and a member of the American Academy of Neurological Surgeons, the Congress of Neurological Surgeons, and its Tumor Section. His personal mission is to help patients obtain relief from pain and suffering in the most compassionate and least invasive way possible, and patients consistently describe his surgical outcomes and his team's care as exceptional.

Dr. Johnson earned his Bachelor of Arts from Northwestern University and then completed his Doctor of Medicine and Doctor of Philosophy simultaneously at Washington University in St. Louis, one of the country's premier academic medical research institutions. He completed his General Surgery internship and Neurosurgery residency at Yale-New Haven Hospital in New Haven, Connecticut, a major academic medical center affiliated with Yale School of Medicine. He subsequently pursued specialized training at Barrow Neurological Institute in Phoenix, Arizona, recognized as one of the world's leading neuroscience centers, as well as advanced coursework in skull base surgery, global spine techniques, and cervical and lumbar disc replacement at training programs in Memphis, Chicago, West Palm Beach, and Cincinnati.

Dr. Johnson is a Fellow of the American College of Surgeons (FACS) and a member of the American Academy of Neurological Surgeons. He completed his neurosurgery residency at Yale-New Haven Hospital and holds both an MD and a PhD from Washington University in St. Louis. He is also a member of the Congress of Neurological Surgeons and its Tumor Section. Patients seeking specific board certification details can contact Neuroscience Group directly or reference his fellowship through the American College of Surgeons member directory.

Dr. Johnson is a neurosurgeon with extensive expertise across brain, spine, and peripheral nerve conditions, with particular depth in brain and spinal cord tumors, brain aneurysms and vascular malformations, brain and spinal trauma, stroke prevention and treatment, and degenerative spine conditions. His Congress of Neurological Surgeons Tumor Section membership reflects a specific focus on neurosurgical oncology. He has a special interest in developing and performing minimally invasive approaches to neurosurgical problems, including endoscopic techniques for brain tumors and hydrocephalus, minimally invasive spine surgery, and cervical and lumbar disc replacement.

Dr. Johnson's stated mission is to help patients obtain relief from pain and suffering in the most compassionate and least invasive fashion possible. His training at Washington University and Yale, combined with specialized coursework at Barrow and multiple advanced surgical technique programs, has given him a broad toolkit that allows him to match the approach to the patient rather than defaulting to a single method. Patients describe him as consistently caring, with a staff team that reflects the same values, and his surgical outcomes — including neck and spine surgery cases where patients report rapid recovery and lasting pain relief — reflect his commitment to minimizing impact while maximizing results.

Dr. Johnson treats a wide range of brain, spine, and peripheral nerve conditions including brain tumors and spinal cord tumors, brain aneurysms and vascular malformations, hydrocephalus, brain and spinal trauma, stroke (both surgical prevention and treatment), degenerative spine conditions, disc herniation, and spinal stenosis. His Tumor Section membership within the Congress of Neurological Surgeons reflects particular depth in the surgical management of brain and spinal tumors. He also treats conditions amenable to minimally invasive and endoscopic neurosurgical approaches, including complex cases that might otherwise require open surgery at a larger academic center.

Dr. Johnson performs a broad range of neurosurgical procedures with an emphasis on minimally invasive and endoscopic techniques wherever clinically appropriate. His procedural expertise includes brain tumor surgery using endoscopic approaches, treatment of brain aneurysms and vascular malformations, hydrocephalus management, minimally invasive spine surgery, cervical and lumbar disc replacement, spinal fusion, skull base surgery, and surgical prevention and treatment of stroke. His training at Barrow Neurological Institute and his advanced coursework in skull base, global spine, and disc replacement give him access to a range of techniques that allow many patients to be treated with less disruption, shorter recovery times, and reduced pain compared to traditional open approaches.

Dr. Johnson sees patients at six Neuroscience Group locations: Appleton OSP, Berlin, Green Bay Prevea, Neenah, New London, and Waupaca. His presence across this broad range of locations — including the New London and Waupaca community offices — means that patients across a wide area of Northeast and Central Wisconsin can access his neurosurgical expertise without traveling to a major academic medical center. For surgical procedures, patients are typically seen at the Neenah main clinic or Appleton OSP locations, which are equipped with on-site imaging, MRI, and procedure facilities.

To request an appointment with Dr. Johnson, use the online appointment request form on his provider page at neurosciencegroup.com or call Neuroscience Group at (920) 725-9373. A scheduling team member will coordinate your appointment at whichever of his six locations is most convenient for you. Before your visit, you will be asked to complete registration and medical history paperwork. If you are being seen for a brain tumor, aneurysm, complex spine condition, or other neurosurgical concern, bringing prior imaging and any relevant records will help Dr. Johnson provide the most complete evaluation at your first appointment.

At your first appointment, Dr. Johnson will conduct a thorough neurosurgical evaluation, reviewing your imaging, medical history, current symptoms, and any prior treatment or surgical history. He will explain your diagnosis and walk through the available treatment options — including both nonsurgical management where appropriate and the surgical approaches he is trained to perform — so you can make a fully informed decision about your care. His philosophy of seeking the most compassionate and least invasive path to relief means that he will not recommend surgery unless it is clearly the best option for your situation. Patients consistently describe his consultations as thorough, reassuring, and focused on their wellbeing rather than rushing to a procedure. Neuroscience Group's Neenah clinic has on-site MRI and imaging capabilities, so additional diagnostic workup can often be arranged in the same location if needed.
