Dr. Ashish Sonig, MD

Ashish Sonig, MD, FAANS, is the region’s first dual vascular trained neurosurgeon and a fellowship trained skull base neurosurgeon who offers treatment for complex cerebrovascular disease and many brain and spinal cord conditions. He specializes in open and endovascular approaches depending on your particular needs. You’ll find comfort and compassion throughout the surgical journey as Dr. Sonig openly communicates with you, your family and the medical team.

Dr. Sonig completed a neurosurgical residency at University of Buffalo in New York, leading to his board certification in neurosurgery (American Board of Neurological Surgery). During his residency, Dr. Sonig won a grant award for research from Brain Aneurysm Foundation and he received the prestigious Galbraith Award from Congress of Neurological Surgeons. His first fellowship in skull base neurosurgery took place at LSU Health Sciences Center-Shreveport School of Medicine. He returned to University of Buffalo for a CAST-accredited endovascular neurosurgery fellowship (Committee on Advanced Subspecialty Training). Regarded as one of the world’s best, the Buffalo fellowship is considered the birthplace of neuroendovascular surgery and it trains the most neurosurgeons in this specialty.  

Keeping up with medical advances that benefit patient outcomes is important to Dr. Sonig. His own research is well published with more than 200 peer reviewed papers, book chapters, abstracts and oral presentations. He is a peer reviewer for reputable neurosurgical journals and is invited to speak at national and international conferences.

Outside the clinic, Dr. Sonig enjoys painting, cycling and hiking. He has two daughters and his wife is an OB-GYN.

At Willis Knighton Health, Dr. Sonig serves as director of Neurovascular Institute of Shreveport and as medical co-director of stroke.
