Dr. Marquez has been my neurologist for roughly 12 years--not long after I was diagnosed. I first saw him at Froedert, and followed him to Aurora. He has been a lifeline for me.
He is the Best Doctor!!!
The waiting time for an appointment is way to far out!
Dr. Marquez explained everything very well!
Don't know what I'd do without Dr. Marquez. He helped me with my headaches when others didn't.
Dr Marquez is always so kind and takes the time to explain and listens to you.
I like Dr. Marquez de Leon MD in how he answered my questions and his check up. I felt relief after my visit.
Dr. Marquez is incredibly intelligent and changed my life for the better.
Personal, attentive, attractive
Exceptional doctor. Both caring and skilled.
