John Y.K. Lee, MD, MSCE - Brain Surgeon Dr. Lee has a passion for minimally invasive surgery for brain tumors, skull base tumors, and trigeminal neuralgia. Endoscopes and fluorescent dyes!

I am passionate about minimally invasive surgery employing novel techniques to improve visualization and maximize outcomes. I have pioneered novel endoscopic techniques for trigeminal neuralgia, hemifacial spasm as well as tumor resection through nose and behind the ear. I have also pioneered novel techniques for fluorescent guided tumor visualization.

Learning new skills on track reminds me of being a new faculty member in neurosurgery.

In residency, you learn how to do basic neurosurgery. As a teenager, you learn how to drive a car with basic skills (including stick shift/manual). However, it is not until you are an attending faculty that you really learn how to operate. You are practicing and refining your craft. Similarly, it is only on the track that I am truly learning how to drive.

Repetition, instruction and video analysis seem to be keys to getting better.

When I started this year, my lap time was 1:48. On the thirteenth track day, my lap time was 1:34. I can't wait until next season.
