About Us

About Us

People with neurological conditions in East Cobb and surrounding communities have access to expert care close to home. Our top-rated neurosurgeons work closely with specialists across the system to provide the most accurate diagnosis and personalized and comprehensive care. Wellstar neurosurgeons collaborate with each other and with experts in other specialties to help patients have the best outcomes.

While brain and spine surgery is our specialty, it is not always our recommended treatment for patients. Sometimes we recommend alternative treatments such as physical therapy and pain management for spine conditions or radiation oncology treatments for brain tumors. When no other treatment path is likely to be successful, surgical solutions for brain conditions, spine disorders and back and neck pain are recommended.

Our neurosurgeons perform a variety of minimally invasive procedures and complex surgeries at Wellstar Kennestone Regional Medical Center.

Brain surgery

We care for people with complex brain conditions, including:
  • Primary and metastatic cancer
  • Non-cancerous brain tumors
  • Brain trauma
  • Hydrocephalus
  • Facial pain
  • Stroke

Spine surgery

Our neurosurgeons perform a variety of minimally invasive procedures and complex surgeries, including:
  • Cervical disk replacements and fusions 
  • Lumbar diskectomy and laminectomy surgery for low back pain syndromes
  • Peripheral nerve decompression surgery for various conditions, including carpal tunnel syndrome and compression neuropathies
  • Spinal deformity correction surgery 
  • Spine trauma surgery
  • Surgery for spinal cord tumors (cancerous and benign)
  • Spine surgery for many other conditions

Patient Rating

I joined Wellstar in August 2010, after spending three years as an assistant professor of neurosurgery at Emory University. I attended medical school at Loyola University Chicago, Stritch School of Medicine. I completed my internship in general surgery at Loyola University Medical Center, where I was named Resident of the Year in 2001. I completed my six year neurosurgery residency at Loyola University Medical center. I have specialty training in complex spinal disease, adult spinal deformity, and spinal oncology. I have training In advanced neuro-oncology techniques for removing brain tumors safely, and In some patients, without making a large incision. I use high definition scopes and video to remove some tumors through small "key-hole" openings in the skull or sinuses. My approach to neurosurgery is best described as patient-centered. I spend time with my patients, and I talk to them, not at them.
