Provider Expertise

Clinical Interest for Patients

Cerebrospinal fluid leaks both spontaneous and secondary. Degenerative and traumatic spinal disorders--from the base of the skull down to the neck and back as well as the tail bone and sacro-iliac joints. Cranio-vertebral junction disorders. (Arnold) Chiari Malformation. Minimal Access / minimally invasive surgical techniques.


Care Philosophy

While having practiced the full breadth of neurosurgery my work has increasingly focused on the many complicated spine problems that so many suffer from. These problems include common issues of the degenerative spine such as herniated discs to tumors and spinal fluid leaks. From outpatient, minimally invasive surgeries to large complex deformity operations there is no problem too little nor too great that does not interest me. Even as a surgeon, it is still my hope to help you in non-surgical ways when possible, but I will be committed to developing whatever plan is required to solve your problems. I place great emphasis on helping you understand your problem in straight forward terms. I will respect you as a partner in maintaining your health and will listen and seek to understand your questions and concerns so that we can work together to make treatment plans that meet your needs.

Interests & Activities

Personal Interests

I have a passion for my work and continue to study and learn the science and art of neurosurgery and spine surgery even outside the traditional work environment. I am often engrossed in contemplating a new treatment or surgical procedure and figuring out how I can adopt it to better the lives of my patients. Outside of my profession I enjoy the Colorado outdoors including hiking, trail running, biking, skiing, fishing and camping. Best of all is when I can combine these activities with my wife and 5 boys.
