Ashleigh Dietrick,
PMHNP
Ashleigh, is a board-certified Psychiatric Mental Health Nurse Practitioner. She has a strong background in psychiatric care and a passion for helping others, Ashleigh brings both experience and compassion to Grace Mental Healthcare.
She believes that mental health care should be personal, collaborative, and centered around the individual—not simply a diagnosis. Her goal is to create a space where patients feel comfortable being honest about what they are experiencing while working together to find meaningful ways to improve their quality of life.
Ashleigh provides individualized psychiatric care for concerns including anxiety, depression, ADHD, mood disorders, and other mental health needs. She takes time to understand each patient's history, challenges, strengths, and goals so that treatment can be tailored to the person rather than taking a one-size-fits-all approach.
She is excited to be part of the Grace Mental Healthcare team and to help patients move toward greater stability, confidence, and overall well-being.
