      Dr. Castillo has been very helpful, very kingd and caring to me. I suffered a great deal of pain because the other dermatologist that I worked with in the past misdiagnosed my condition. Dr. Castillo is very knowledgeable and sharp, he researched and cared and diagnosed my condition correctly. My condition has imporved. He is an outstanding dermatologist and human being. I wish all of my other doctors were as caring and as knowledgeable as he is. He has helped me a great deal and I am very grateful for his help
