Hi, I’m Hayley Johnson, MSN, PMHNP-BC. I am a board-certified Psychiatric Mental Health Nurse Practitioner with over 16 years of experience in nursing, including medical, rehabilitation, home health, and behavioral health settings.

I work with adolescents and adults (ages 12+) experiencing anxiety, depression, ADHD, mood disorders, and stress-related conditions. Many of my clients are high-functioning individuals who feel overwhelmed internally, struggle with focus or emotional regulation, or feel stuck despite trying to manage things on their own.

My background in both medical and psychiatric care allows me to take a comprehensive approach. I consider the full picture, including medical history, lifestyle factors, and when appropriate, possible contributors such as thyroid imbalance, vitamin deficiencies, or hormonal changes.

I am committed to providing thoughtful, structured, and evidence-based psychiatric medication management in a way that feels collaborative and respectful.

I have a background in science and psychology, which fits my education as a psychologist. I am also a very creative and collaborative person. I want to work with each client to find the best individual treatment for them. I know many techniques and exercises, but only you can tell me what what works best for you. I enjoy helping adults (age 18+) navigate the transitions they face and be able to look forward to the future with hope (even if that feels very far away currently).
