Villavicencio CV 2021

“By its very nature, neurosurgery is challenging. The challenges are what drew me to the specialty. Another reason is these patients need resolution. Often the resolution is relief from longstanding suffering. In many cases, life is in the balance. For me, caring for these patients is the very essence of medicine and has fueled my pursuit of excellence. I perform outpatient procedures that many surgeons still perform as several hour long open surgeries that require several days of hospitalization. My colleagues and I provide care for patients throughout the region, not only in Colorado, but in other states and countries such as Montana, Wyoming, Texas, California, Florida and Canada. The level and quality of care provided by Boulder Neurosurgical & Spine Associates is comparable to the best centers in the world. Personally, I stop at nothing to help patients get their lives back.”
