Dr. Disney is no longer accepting office patients.
Dr. Disney believes that patients need an individualized approach to their neurosurgical problems. This includes complex disorders of the spine and brain as well as peripheral nerves. There is no substitute for listening carefully to patients and guiding them to the best approach to their problem. Many problems of the spine and brain give rise to pain or other impediments to quality of life. Dr. Disney utilizes conservative treatments where appropriate to help resolve these problems and return individuals back to active pain free lives. Many patients don’t need surgery but instead find relief with physical therapy, exercise and activity modification. When needed surgery is performed in the least invasive way possible consistent with alleviating the patient’s symptoms and problems.
A frequent recipient of top doctor awards, patient choice awards and most compassionate doctor awards Dr. Disney takes the time to listen carefully to patients concerns and fears. Treatment options are laid out in layman’s terms to allow patients to understand their choices and what is being recommended to them. Most neurosurgical disorders have more than one possible approach to treatment and it is important to empower patients to make the choice that is correct for them.
A graduate of McMaster University in Hamilton Ontario, Dr. Disney initially studied Engineering Physics and later medicine. The critical thinking and problem solving skills of engineering have been applied to neurosurgery with success. A surgical internship at the University of Toronto was followed by Neurosurgical Residency and Fellowship at the University of Alberta where he also obtained a PhD in Experimental Surgery. Dr. Disney has practiced in the same group practice in Southern California since finishing residency. The practice’s name has changed but what has not is a patient centric approach dedicated to achieving the best possible patient outcomes. All the partners of the group share the same philosophy. When not engaged in neurosurgery Dr. Disney enjoys spending time with his family and is an avid skier, cyclist and aviator.

The team treats a vast array of neurological conditions. After intensive neurological exams and diagnostic testing, they recommend the best nonsurgical treatments for each person's unique health care needs. They recommend surgery when symptoms are severe or persist despite conservative care.
Patients seek Dr. Mesiwala for his expertise in brain and spine surgery, as well as peripheral nerve surgery and artificial disc replacement surgery.
He's an expert in complex brain and skull base surgeries, and he has the most experience in artificial disc replacements on the West Coast, including multi-level operations and all types of spinal decompressions.
Dr. Mesiwala is a leader in the field of minimally invasive sacroiliac (SI) joint surgery and has performed endoscopic cranial and spinal surgery since 2004. No matter where pain originates, patients get relief after he performs neuromodulation surgery.
After earning a Bachelor of Science in biomedical engineering and electrical engineering from Johns Hopkins University in Baltimore, Maryland, Dr. Mesiwala received his Doctor of Medicine from the University of California, San Francisco.
Then he finished his neurological surgery residency at the University of Washington in Seattle, Washington.
He completed his skull base and cerebrovascular fellowships at the University of Washington, International Neuroscience Institute in Hannover, Germany, and the University of Pittsburgh in Pittsburgh, Pennsylvania.
As a respected researcher specializing in the development of novel technologies and minimally invasive techniques for brain and spine surgery, Dr. Mesiwala holds multiple patents for medical devices used in spinal surgery.
In addition to his private practice, Dr. Mesiwala is the faculty surgeon for various artificial disc operations and spinal fusion operations with innovative techniques. He's a fellow of the American Association of Neurological Surgeons (FAANS).
“I am very pleased with Dr. Mesiwala and all his staff. everyone is always eager to help and answer questions. I am always kept up to date with my appointments and any changes that may occur.”
