ADHD affects focus, impulse control, and emotional regulation differently for everyone. Headway's Mountain View network offers providers trained in practical strategies, psychoeducation, and strengths-based approaches to help you build confidence and manage hyperactivity or inattentive symptoms.
I am dual board-certified as a psychiatric-mental health nurse practitioner and family nurse practitioner with a passion for functional medicine. I believe mental health is best addressed by looking at the whole person—mind, body, and soul. I’ve been working in healthcare for over 20 years. Through my experience in mental health, I have the privilege of working with adults aged 21–60. I support individuals navigating anxiety, depression, ADHD, PTSD, OCD, mood disorders, and eating disorders, offering a safe and respectful space for growth and healing.
With over a decade of acute care experience as a Registered Nurse and a Master’s degree as a Psychiatric Mental
Health Nurse Practitioner, I specialize in treating mood disorders, anxiety, PTSD, neurodiversity, and medication
management.
My goal is to empower people to look at the bigger picture of what is possible for them.
I genuinely like people, have always love to help ,
Will take my clients through the therapeutic process, with empathy and care for their experience in therapy to be a positive one.
Welcome! I am Dr. Lyssabeth Mattoon, PhD, a clinical psychologist and trauma specialist, skilled at providing individual and family therapy for adolescents, children and adults. My calling in life is to support and empower trauma survivors to harness their inner strength as part of the healing process.
