Rooted in Compassion.
Driven by Purpose.
We all carry something. Life is full of personal struggles — and your mental health is at the center of how you navigate all of it. Nourishing it isn't a luxury. It's how you take control, practice real self-care, and show up as your best self for the people and things that matter most.

Brittany Castillo, PMHNP-BC, MSN
Psychiatric Mental Health Nurse Practitioner · Metairie, Louisiana
Brittany is a board-certified Psychiatric Mental Health Nurse Practitioner who earned her Master of Science in Nursing from Nicholls State University. She has built her career across inpatient, outpatient, crisis, and community-based psychiatric settings — bringing a depth of clinical experience that spans the full spectrum of mental health care.
Her clinical background spans some of the region's leading behavioral health facilities, outpatient clinics, and community-based settings — with specialized focus on ADHD, addiction and substance use disorders, geriatric psychiatry, schizophrenia, bipolar disorder, major depressive disorder, and anxiety disorders.
Outside of the office, Brittany is a devoted mother and wife. Family and close friendships are at the core of who she is. She is a firm believer in practicing what she preaches — prioritizing self-care, staying grounded, and finding joy in everyday life. She is also a proud animal lover with what she lovingly calls a "zoo" at home.
That personal perspective — knowing firsthand how much life demands of us — is exactly what drives her passion for psychiatric care. She understands that mental health isn't separate from the rest of your life. It is the foundation of it.
"You are more than a diagnosis. You are a whole person — and that is exactly how I will treat you."
We Are All Fighting Our Own Battles
Every single one of us is navigating something personal. Life is hard — and mental health sits at the very center of how we cope, connect, and carry on. It shapes how we parent, how we love, how we work, and how we see ourselves.
Nourish Your Mind
Just like your body needs food and rest, your mind needs care and attention. Investing in your mental health is not weakness — it is wisdom.
Take Back Control
Mental health care gives you the tools to understand your patterns, manage your emotions, and make choices that align with the life you actually want.
Self-Care Is Not Selfish
When you prioritize your mental wellbeing, you show up better for everyone around you — your family, your work, your community, yourself.
