Dr. Rigi is a Naturopathic Doctor specializing in holistic mental health and functional medicine, offering a root cause approach to anxiety, depression, ADHD, trauma, and chronic stress. She works with teens and adults who are ready for more than symptom management. Her philosophy is simple: when you understand the body, you unlock the mind.
Using advanced functional medicine strategies, Dr. Rigi identifies the biological patterns influencing mood, focus, and emotional regulation. Nervous system overload, inflammation, micronutrient deficiencies, sleep disruption, and metabolic stress can all shape how you feel and function. By addressing these underlying drivers, she helps patients move from survival mode into steadiness, clarity, and resilience.
Her care supports the full spectrum of mental health needs, from ADHD and anxiety to depression, trauma recovery, and stress-related burnout. Through comprehensive evaluation and personalized treatment planning, she strengthens executive functioning, emotional balance, nervous system regulation, and overall cognitive performance.
With a deep commitment to teen mental health, she creates a calm, structured, judgment-free space where adolescents navigating academic stress, anxiety, mood changes, social pressures, and the challenges of growing up feel genuinely heard, supported, and equipped with practical tools to thrive.
This is care built for long term results. Every treatment plan is intentional, collaborative, and tailored to your biology and your life.
The aim is not simply to help you cope. It is to help you think clearly, feel emotionally steady, and show up fully in your relationships, work, and daily routines with confidence and strength.
