Meet Our OC Care+Cure Neurosurgeons

Dr. Sumeet Vadera (University of California, Irvine Health)

Dr. Sumeet Vadera is a fellowship-trained UC Irvine Health neurosurgeon who specializes in epilepsy surgery, with expertise in minimally invasive surgery for adult and pediatric patients with epilepsy.
His clinical expertise is in neuromonitoring, specifically subdural grids and stereoelectroencephalography (SEEG), and the early treatment of patients with medically intractable epilepsy. He performs laser surgery to treat deep epileptic lesions in the brain, using minimally invasive techniques as well as implantation of the Neuropace RNS® (responsive neurostimulation) device.
Vadera is the first neurosurgeon on the West Coast to use a neurosurgical robotic device for precise mapping and positioning when performing minimally invasive cranial procedures, such as SEEG.
Vadera also treats patients with cervical degenerative disease and syringomyelia, spine deformity and spine tumors, and a wide range of neurological conditions, including brain tumors, hydrocephalus, Chiari malformation, spine and cranial trauma, and concussion.
He earned his medical degree at Jefferson Medical College in Philadelphia, Penn., and completed a neurosurgery residency and a fellowship in epilepsy surgery at the Cleveland Clinic Foundation in Cleveland, Ohio.
Vadera is the lead author of several publications related to epilepsy surgery and outcomes in major neurosurgery journals. He also is an ad hoc reviewer for several journals. He is currently a member of the Congress of Neurosurgeons (CNS), the American Association of Neurosurgeons (AANS) and the Society for Brain Mapping Techniques (SBMT).

Dr. Joffre Olaya (Children’s Hospital Orange County)

Dr. Joffre Olaya performs the full range of pediatric neurosurgical procedures, including the treatment of brain/spine tumors, cerebrovascular lesions, chiari malformations, neural tube defects, craniosynostosis and hydrocephalus, as well as intractable epilepsy.
As a contributing neurosurgeon, Dr. Olaya enhances the CHOC Comprehensive Epilepsy Program, the first children’s hospital program in California to receive the prestigious Level 4 distinction from the National Association of Epilepsy Centers. Dr. Olaya is further developing the CHOC epilepsy surgery program, working closely with the other pediatric subspecialty services, and continuing to foster a multidisciplinary approach for optimal patient care. He is interested in the leading-edge technology that is making pediatric neurosurgical procedures safer and less invasive.  Dr. Olaya’s research on deep-brain stimulation for treating childhood dystonic cerebral palsy has been published in the Journal of Neurosurgery.
Dr. Olaya is a graduate of the University of California at Davis School of Medicine. He completed his neurological surgery residency at Loma Linda University Medical Center. As a resident, he performed an elective rotation in pediatric neurosurgery at Children’s Hospital Los Angeles and then completed a postgraduate pediatric neurosurgery fellowship at Children’s Hospital Los Angeles.   Dr. Olaya served his fellowship in epilepsy surgery through the University of Washington at Seattle Children’s Hospital.  Dr. Olaya is an assistant clinical professor in the Department of Neurosurgery at UC Irvine School of Medicine.
