Book a therapist or psychiatrist in Arizona covered by United Healthcare

Hello and welcome! my name is Darren Nguyen (Duy), I'm currently only taking new clients for individual therapy, not couple and family therapy. I'm a Licensed Professional Counselor dedicated to helping individuals navigate life’s challenges and achieve meaningful growth. I earned my Master’s degree in Counseling with an emphasis on Mental Health Counseling from the University of Arizona and have experience working in a community mental health clinic, supporting individuals facing a range of emotional and psychological struggles. Growing up in two different cultures, I understand how cultural influences shape identity, values, and personal experiences, allowing me to provide culturally responsive care that acknowledges the intersection of mental health and cultural background. I specialize in treating anxiety, depression, trauma, borderline personality disorder, and attachment-related concerns using a person-centered, strength-based, and trauma-informed approach. Integrating evidence-based modalities such as ACT, CBT, DBT, PRT and somatic therapy, I help clients cultivate resilience, self-awareness, and lasting change. My goal is to create a safe, collaborative space where clients feel heard, understood, and empowered to explore their emotions, challenge unhelpful patterns, and build a life aligned with their values. Whether you're struggling with past trauma, self-doubt, or emotional distress, I am here to provide compassionate guidance and effective therapeutic strategies tailored to your unique journey.
