After finishing her travel assignment, Deborah decided to start working as a Psychiatric nurse and worked for institutions including Banner Behavioral Health, Phoenix Childrens Hospital, and Arizona State Hospital where she obtained experience with the children, adolescents, and adult population.

Samantha Willen, DNP, PMHNP-BC,

My name is Samantha Willen, and I am a Psychiatric Nurse Practitioner at SMHWI. I earned my Doctor of Nursing Practice from the University of Arizona and am board certified in Psychiatric-Mental Health.

I specialize in anxiety, depression, and substance use disorders, working primarily with adults with co-occurring disorders. My approach to care is collaborative and strengths-focused, emphasizing each client’s unique resilience and capacity for growth. I often use cognitive-behavioral therapy (CBT), and mindfulness-based interventions to help clients build insight and develop practical coping skills.

I chose this profession because I have a family member who struggled with mental health challenges, and that experience showed me how important compassion and understanding are in the healing process. I find it most rewarding to build meaningful relationships with my clients and help them feel better and more hopeful about their lives.

Outside of work, I enjoy spending time with my husband and two daughters, and indulging in my guilty pleasure of watching Bravo shows.
