Dara Castillo

I’m Dara Castillo, a board-certified Psychiatric Mental Health Nurse Practitioner and doctoral nursing candidate. I help adults navigate anxiety, ADHD, and mood concerns through an approach that considers both symptoms and the context behind them. My work brings together evidence-based psychiatric care with attention to sleep, stress, nutrition, behavior, and physiology. I value medication when it’s helpful, thoughtful use of supplements when appropriate, and practical strategies that fit real life. My goal is to help you understand your patterns and make informed decisions about your mental health, without unnecessary complexity or one-size-fits-all recommendations.
