Shannon Mostafiz

Shannon Mostafiz, PMHNP-BC

I’m Shannon—an integrative, board-certified Psychiatric Nurse Practitioner with a passion for helping people reconnect with their wholeness. I specialize in trauma-informed care, holistic mental health, and consciousness-based healing, combining deep clinical training with a belief that mental health is about more than just managing symptoms—it's about reclaiming your agency, vitality, and ability to thrive.

I hold a Master’s degree from Hunter College, completed clinical rotations at Bellevue Hospital, and earned my undergraduate degree from Maharishi International University, where meditation and consciousness were part of daily life. I’ve worked in both traditional hospital settings like New York Presbyterian and in innovative mental health environments including Mindbloom, where I provided at-home ketamine-assisted care. I now lead Floresta Retreat, a company I founded to help others access deeper transformation through consciousness-based retreats and advanced healing modalities.

Clients often say I bring a sense of safety, creativity, and nonjudgmental presence to our work together. I’m deeply curious about how trauma, identity, and awareness shape the human experience—and I integrate tools from somatic energy release, functional medicine, and spiritual psychology to help people move beyond anxiety, depression, and burnout.

Outside of sessions, I’m probably hiking Colorado’s mountains, dancing, writing, or building new ways to bring healing and innovation together. I’m currently writing a book called The Mind Lies: Moving Beyond Anxiety and Depression and facilitating groups that explore personal growth through unconventional but deeply effective practices.

Whether you’re feeling stuck, questioning your purpose, or simply ready to explore what else is possible—I’m here to support your journey with curiosity, truth, and compassion.
