We were very impressed with Dr. Montero--especially after the nurse told us he was not scheduled to work that day, but came in to see me.

Dr. Montero used and told me I did not need Chemo even though my onco score is 27. He did not seem interested in listening to my concerns regarding my onco score. I drove 10 hours round trip to get a second opinion. Since then my local doctor presented my case to 5 other head oncologist in the US and they all agreed I need chemo based on my onco score alone. Just using alone does not apply to all patients with intermediate high onco scores.
