About Armstrong PMHNP

I’m Jennifer, and I’m glad you’re here.

Jennifer Armstrong, PMHNP providing psychiatric care for children, adolescents, and adults

Jennifer Armstrong, MSN, APRN, PMHNP-BC

I'm a board-certified psychiatric mental health nurse practitioner providing psychiatric care to children (7+), adolescents, and adults across Missouri, Illinois, and Kansas. I work with patients navigating anxiety, depression, mood disorders, ADHD, trauma, gender dysphoria, women's mental health, and other psychiatric concerns.

My background spans more than 20 years in healthcare, including high-intensity emergency settings and behavioral health leadership. My foundation in medication management began early in my career as a pharmacy technician, and that depth continues to inform how I approach prescribing today. These experiences shaped the way I practice — calm, thoughtful, and clinically thorough.

I believe in care that is collaborative and individualized, with treatment plans that feel personalized, practical, and sustainable. My goal is to help you move past the obstacles that feel overwhelming and toward a life that is balanced, manageable, and fulfilling.

I'm passionate about helping patients find clarity in their thoughts, stability in their emotions, and confidence in their daily lives — and I feel honored to walk alongside them in their mental health journey.
