I'm Rachael Colley, a Psychiatric Mental Health Nurse Practitioner specializing in psychiatric medication management with a practical, skills-based approach. Every visit goes beyond a prescription check. We will work together so you leave each appointment with a clear medication plan and concrete strategies you can actually use in your daily life.
My background as a nurse and former educator shapes how I practice: I explain things clearly, I involve you in every decision, and I focus on what works in real life, not just what looks good on paper.
Who I work with
I see adults, teens, and children, with a particular focus on ADHD, anxiety, depression, mood disorders, perinatal and postpartum mental health, and binge eating disorder. I provide neurodiversity-affirming care and have a strong interest in supporting people who are navigating a late diagnosis, including the relief of finally having answers and the practical work of figuring out next steps.
I earned my degree in psychology, and a gap year with Jesuit Volunteer Corps in a social justice setting led me to social work. I use a systems approach, meaning I look at the personal, family, and life factors affecting your well-being. My background in foster care, crisis work, community-based care, and therapy gives me a collaborative, well-rounded perspective.
You should know that I truly see you — not just your symptoms or diagnosis. Many clients come to me feeling anxious, depressed, overwhelmed, scattered, or stuck — often after feeling unheard or dismissed by other providers. My goal is to understand the full picture — your goals, challenges, and values — and create a space where you feel safe, supported, and empowered throughout your care. I work with children, teens, and adults experiencing anxiety, depression, ADHD, trauma, and other psychiatric concerns.
I combine evidence-based psychiatry with a holistic, personal touch. Care with me is collaborative, thoughtful, and never rushed. I don’t push medications or rely on quick fixes — I work with you to find clarity, balance, and lasting relief through treatment that fits your life.
I am a Licensed Professional Counselor, holding a Master of Science in Professional Counseling from Grand Canyon University. With a deep commitment to fostering transformation and growth, I specialize in creating a therapeutic space where clients feel empowered to explore their inner potential. My approach is grounded in building a collaborative and relational connection, ensuring that each client feels heard, supported, and safe throughout their journey.
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.
