Hi, I’m 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’m fluent in both English and Spanish.
Although I’ve 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 issues, LGBTQIA+ and identity concerns, and relationship challenges, as well as anxiety, depression, trauma, PTSD, anger, grief and loss, cultural and ethnic issues, maternal and men’s issues, 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.
I’m a Florida-based PMHNP with a strong background in trauma-informed, culturally competent care. I’ve supported diverse clients across acute, outpatient, veteran, and dual-diagnosis settings—delivering psychiatric evaluations, med management, and therapeutic support in collaboration with interdisciplinary teams.
I believe therapy is not about “fixing” you-It’s about empowering you. Together, we will work to uncover your strengths, clarify your goals, and build skills that support meaningful, lasting change. Whether you are feeling overwhelmed, stuck, or simply seeking personal growth, I’m here to walk alongside you in this therapeutic process.
I look forward to connecting with you.
