Functional neurosurgeon specializing in spine surgery, movement disorders, and cranial procedures
Dr. Abhijeet Gummadavelli is a fellowship-trained functional neurosurgeon with Neurosurgery One in Littleton. He provides comprehensive neurosurgical care, including spinal surgery, cranial surgery and movement disorder diagnosis and surgery. With his specialization in functional neurosurgery, “Dr. G” approaches his cases from a network perspective. No matter how routine or complex the patient’s condition, he focuses on understanding and treating the underlying neurological network, whether that is a movement disorder network or a pain network.
Dr. Gummadavelli’s practice focuses on spine and cranial procedures. He diagnoses and treats craniofacial pain, spasticity, and all types of spinal issues, including refractory back pain. He is extensively trained in minimally invasive spine surgery and applies the latest proven procedures to best meet his patients’ needs.
In addition to spinal and cranial surgery, Dr. Gummadavelli also specializes in treating movement disorders and uncontrolled seizures. Dr. Gummadavelli works closely with the epilepsy team at AdventHealth Littleton to provide comprehensive seizure treatment. He is skilled in stereoelectroencephalography (stereo-EEG) to pinpoint seizure-generating networks, which leads to more precise diagnoses and treatment planning. Dr. Gummadavelli performs all types of epilepsy surgery, including Deep Brain Stimulation (DBS), NeuroPace responsive neurostimulation (RNS), vagus nerve stimulation (VNS), laser ablation (LITT), and resections.
He is passionate about helping patients understand the complexity of their condition through simple, clear language. He particularly enjoys working with patients who have not experienced relief from previous treatments or surgeries, approaching their care with a fresh perspective and offering the latest evidence-based treatment options to restore hope and help them achieve their goals.
Dr. Gummadavelli earned his medical degree from Yale University School of Medicine, completed his neurosurgery residency at Yale-New Haven Hospital, and pursued fellowship training in stereotactic, functional, and epilepsy neurosurgery at Vanderbilt University. Dr. Gummadavelli is board-eligible and is fulfilling his post-residency practice requirement to become board-certified.
I love that you are always smiling, making me feel at ease. As I would have had the right to be, I was never afraid. You are confident and kind. You listened to me and my husband too. You acknowledged our concerns with patience and understanding and acted upon them appropriately. I am so much better, I can't begin to thank you!

Patient Success Stories
” We call Dr. Gummadavelli ‘Miracle Number One’ in our household.”
“I really appreciate that Dr. Gummadavelli did not sugarcoat anything. He was very straightforward with what I had to face, then that prepares me for what’s going on after the surgery. It prepared me very well, because I’m doing great now.”
- Movement Disorders
“If anything were to change and I were to have seizures again, I know Dr. Gummadavelli will continue to work with me and be the best advocate I could ask for.”
Ashley Rodriguez
Registered Nurse
“Something I would tell people with epilepsy who have never had surgery for it…you’re not alone in this journey, and there’s whole teams of doctors just looking out for you.”
