Obsessive-compulsive disorder therapists & psychiatrists in Glendale, AZ

I’m a warm, direct, and collaborative therapist who believes therapy should feel both supportive and purposeful. I create a space where you don’t have to minimize your pain or have everything figured out. I work best with clients who want to understand themselves more deeply, heal from emotional wounds, and make meaningful changes. I value honesty, curiosity, and practical tools, and I’ll meet you with compassion while also helping you gently challenge patterns that keep you stuck

I'm Rachael Colley, a Psychiatric Mental Health Nurse Practitioner focused on psychiatric medication management with a practical, skills-based approach. My path ran through teaching and nursing before prescribing, so explaining things in plain language comes naturally, and I care about what works in your real life, not just what looks good on paper.

Who I work with I see adults, teens, and children, with particular depth in 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 navigating a late diagnosis, both the relief of finally having answers and the practical work of figuring out what comes next.

I offer early morning, evening, and weekend appointments across Arizona.

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.
