    Because Dr. Castillo is very professional, knowledgeable, accessible, courteous, kind, returns calls promptly, he cares about my health, and I have complete trust in him as does my husband who is also his patient. I’m also very grateful to Dr. Castillo for his patience and I pray he will always be my primary doctor. To me he’s the best primary doctor I’ve ever had.
