“I believe in a team-based approach to medicine where we treat the whole person, not just a particular disease process.”

— Dr. Ko

What inspired you to pursue a career in medicine?

Both of my parents are physicians. When I was growing up, I didn’t intend to follow in their footsteps. In fact, I was a philosophy major in college. But then my brother experienced a life-altering injury to his spinal cord. I took some time off from school to help take care of him, and it was then that I started to consider going into medicine. There were many influences along the way that led me to specialize in neurosurgery, but that experience emphasized for me how much there is still to learn about the brain and other parts of the nervous system. Neurosurgery felt like an area where I could make a big difference in the lives of patients through both direct care and research.

How do you help patients?

Collaboration is the foundation of my practice. I work with a variety of multidisciplinary specialists to develop surgical treatment plans that safely maximize your neurological health and functionality without causing deficits. We prioritize your individual goals as well as your quality of life. I believe in a team-based approach to medicine where we treat the whole person, not just a particular disease process.

Provider Background

Specialty: Surgery

Brain, spinal, peripheral nervous system tumors, other neurological conditions

I specialize in functional neurosurgery, which focuses on restoring or preserving functionality in the nervous system, from the brain and spine to nerves throughout the body. The goal is to improve a person’s quality of life or correct a problem caused by a neurological condition, such as brain tumors or Parkinson’s disease. At SCCA, I provide care for patients with cancers affecting the brain, spine or peripheral nervous system. I also treat patients at the UW Medicine Regional Epilepsy Center at Harborview.

My research is focused on using advanced imaging techniques and electrical activity in the brain to better understand and treat neurological conditions. One area of interest is using electrical stimulation in the brain to more effectively address symptoms, such as tremors, that are associated with Parkinson’s disease and similar disorders.

Clinical Trials

We make promising new treatments available to you through studies called clinical trials led by Fred Hutch doctors. Many of these trials at Fred Hutch have led to FDA-approved treatments and have improved standards of care globally. Together, you and your doctor can decide if a study is right for you.

Many of our Fred Hutch doctors conduct ongoing research to improve standards of patient care. Their work is evaluated by other doctors and selected for publication to the United States National Library of Medicine, the largest medical library in the world.
