Won Kim, MD



Dr. Kim completed his neurosurgical residency training at UCLA with a fellowship in stereotactic and functional neurosurgery. His clinical interests include the treatment of primary and metastatic brain tumors deep within the brain using a wide variety of surgical modalities to best suit each individual patient and tumor type. Using technologies including the laser ablation of tumors (Visualase), white matter preserving corridor surgery (BrainPath), and stereotactic radiosurgery, he is able to treat many tumors traditionally deemed “inoperable.”

In addition to the treatment of tumors within the brain, Dr. Kim specializes in advanced endoscopic techniques to surgically remove tumors of the pituitary and skull base. Working hand-in-hand with a multidisciplinary surgical team of otolaryngologists and oculoplastic surgeons, he is able to treat tumors in a minimally invasive manner that avoids large craniofacial incisions and maximizes functional outcomes.
