I’m a Psychiatric Mental Health Nurse Practitioner with over 17 years of experience supporting adolescents, adults, and older adults on their mental health journeys.
My approach is warm, collaborative, and empowering. I believe that understanding yourself is the foundation of healing, and I focus on giving my clients practical tools, education, and guidance they can use every day—not just during sessions.
In our first session, I take the time to truly listen and understand your story, your goals, and the challenges you’re facing. Together, we’ll create a personalized and realistic treatment plan designed to support your growth, emotional well-being, and long-term success.
I am committed to providing compassionate, evidence-based care that helps you feel seen, supported, and equipped to move forward. My goal is to help you build confidence, develop lasting skills, and become the strongest version of yourself—one step at a time.
When we feel othered, alone, or hopeless — it's hard to ask for help. Talking to a therapist can help you feel like yourself again. I help my clients discover the root of their concerns through storytelling, reflecting on their values and desires, and understanding in what ways they’ve adapted to being in the world.

Hello, I am Dr. Arenas Nieves, a licensed therapist in Arizona, Florida, and New York, with over 15 years of experience supporting individuals on their journey toward mental and emotional wellness. I work with adolescents, adults, and seniors, and I am fluent in both English and Spanish.
Although I have worked with many populations throughout my career, my niche includes military service members, veterans, their families, and underrepresented community members such as people of color, neurodivergent individuals, and LGBTQIA+ clients. I specialize in ADHD, family dynamics, LGBTQIA+ identity and exploration, and relationship challenges, as well as anxiety, depression, trauma, PTSD, anger management, grief and loss, cultural and ethnic concerns, maternal and men's mental health, and chronic conditions.
My style is affirming, inquisitive, and solution-oriented. I aim to create a collaborative, judgment-free space where you feel supported, seen, and empowered to make meaningful change.
