For me, trust is the keystone upon which I form the relationships with my patients. Trust is important when asking a patient to share details of problems that can often be embarrassing. And trust is important when asking a patient to let me help them solve their problems, some of which may have been ongoing for years. In order to build that trust, I show my patients warmth and compassion, I listen fully and intently, and I show my patients a warmer side of medicine.

I always make sure to educate my patients fully, so they can make informed decisions and take an active role in their own care.Born and raised in Los Angeles, Dr. Castillo drags her family to the beach as often as possible.
