ADHD therapists and psychiatrists in Flagstaff, AZ

My work focuses on helping individuals through life transitions whether that be in the form of grief, trauma or overall changes happening and causing disruption to your life. I have been in the therapy world for 6 years now and prior worked in community focused organizations. I have training in trauma-informed therapy, as a death comadre, CPP, and perinatal mental health.

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.

I provide psychiatric care in a way that is warm, open-minded, and empowering. My goal is to create a space where you feel comfortable being honest about what is going on, whether you are dealing with anxiety, ADHD, stress, postpartum or maternal mental health concerns, depression, trauma, sleep issues, OCD, eating concerns, or women’s mental health challenges.

I know reaching out for support can feel overwhelming, especially when you are already carrying a lot. I work collaboratively with clients to help them better understand what they are experiencing, identify what is getting in the way, and build a plan that feels realistic, supportive, and aligned with their goals. I want clients to feel heard, respected, and actively involved in their care every step of the way.

I help clients manage anxiety, depression, and stress one step at a time by offering practical tools and supportive, empowering therapy in a safe, nonjudgmental space.

With over 36 years in behavioral health, I've worked across inpatient, outpatient, corrections, education, and management settings — with children, adolescents, adults, and individuals navigating substance use and serious mental illness. But what drives me isn't my resume; it's this: mental illness is a bully, and no one deserves to be bullied. Nobody asked for it, and there is real courage in asking for help. I want to be a rock upon which mental illness breaks — helping people feel heard, seen, and able to enjoy life again. When I'm not working, you'll find me hiking, backpacking, or spending time with my dogs.

With 165+ reviews and a 4.96 rating on Zocdoc, I have specialized in advanced medication management for complex, treatment-resistant conditions. I utilize a neurobiological approach that focuses on frontal lobe/executive functioning, nervous system dysregulation, and neurotransmitter systems to diagnose and treat various concerns - ADHD/executive dysfunction, OCD, trauma/C-PTSD, high-masking autism, personality profiles, and cases where standard medication treatments have failed. While I specialize in clinical complexity, I bring that same deep, careful attention to treating anxiety, depression, and clients starting medication for the first time.

I am an RN with over 18 years of experience in nursing, specializing in mental health care. I am also a PMHNP-BC, and I obtained my first degree from Grand Canyon University and my Masters from Walden University. I manage clients across the lifespan and use a holistic and patient-centered approach.
