Obsessive-compulsive disorder therapists & psychiatrists in Flagstaff, AZ

I specialize in addiction, ADHD and depression for all ages. Listening to clients and working together to find the right approach to their situation. I am a very goal oriented person that uses my knowledge and experience to create a treatment plan that motivates and encourages my clients on their mental health journey.

My priority is to provide a safe, compassionate, and non-judgmental space where you feel heard, respected, and supported. With over 40 years in healthcare—including service as a former Navy Nurse Corps Officer and retired military veteran—I bring values of resilience, trust, and teamwork into every therapeutic relationship. I view care as a partnership and work to empower you to take an active role in your mental health.

I want you to feel like an active partner in your care from day one. My work centers on anxiety, depression, and addiction, and I bring a warm, curious approach to your day to day life before we talk about a plan. Good care happens when we build it together, so you always have a voice in your treatment. Whether something feels newly off or you have managed a diagnosis for years, my goal is to meet you where you are and help you feel more like yourself. I explain the reasoning behind recommendations so it never feels like guesswork, and I want our work to feel collaborative and paced to what helps you.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over 10 years of experience in the mental health field. Throughout my career, I have worked in both inpatient hospital and outpatient settings, caring for individuals with a wide range of mental health conditions across the lifespan.

My passion is women's mental health. I specialize in supporting women through the unique emotional and psychological challenges that can occur during different stages of life, including postpartum, premenstrual dysphoric disorder (PMDD), infertility, menopause, anxiety, depression, and trauma. My goal is to help close the gap in women's mental health care by providing compassionate, evidence-based treatment that empowers women to better understand their mental health and take an active role in their well-being.

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 am a Arizona Board Certified Licensed Professional Counselor (LPC) who has been working in the Mental Health field for the past 8 years. I received my Bachelor's Degree in Psychology at Arizona State University and my Master's Degree in Clinical Mental Health Counseling at Grand Canyon University. I also hold a post-graduate certificate in Marriage and Family Therapy. I have been providing individual counseling for the past 4 years. I am passionate about helping others heal through past trauma.

Outside of therapy, I enjoy traveling and dance—I'm part of a dance team and love exploring new places whenever I can :)
