I specialize in working with teens and adults navigating things like school refusal, emotional dysregulation, anger, self harm, anxiety, depression, OCD, life transitions, and personal growth. I work with teens ages 13 to 18 as well as adults, and my goal is to create a space where you feel understood, supported, and not alone in what you are going through.
Outside of my work, I enjoy being creative, staying organized, and spending time with my husband, our dog, and our two daughters, which helps me stay grounded and connected in my own life as well.
I am a board-certified Psychiatric Nurse Practitioner with a Doctorate in Nursing Practice. I care deeply about creating a safe, supportive space where you feel comfortable being yourself. I work with adults experiencing anxiety, depression, mood disorders, ADHD, PTSD, and stress. I believe that every person’s story matters, and your care should reflect your unique needs and goals.
