What People Say About Dr. Alfredo Leon, MD
Reply
I have Psoriatic Arthritis and Rheumatoid Arthritis and am suffering from joint pain from my hip to my ankle on the right side of my body. He didn't feel he could treat the issue so he convinced a colleague who treats Rheumitoid and Psoriatic Arthritis. Dr. Leon showed concern and compassion to a new patient.
