Dr. MacKenzie ia board certified Adult and Child psychiatric NP and trained therapist Graduated Cum Laud from Case Western Reserve University in 2012 practicing in Texas, Oregon and most recently in Arizona since 2013. Prior to this he spent 10+ years as a Psychiatric and Critical Care RN in the community and a prior 10+ years in the US Army; where he learned a lot about anxiety, depression, grief and trauma. "I lived it, and with help I recovered. Then I studied what I myself have gone through to help others".

"If you think about it, there is no actual health without good mental health, and I work to help my clients achieve both."

Using the tools of Psychology as well as Psychiatric medication management (if appropriate), you can feel much better, function much better at home, work, and when you find yourself in those uncomfortable times.

Almost every symptom or unwanted trait can improve and in many cases, resolve completely, but only if you give it a chance.

I have been in the mental health field for almost 10 years. I spent two years as a case manager for kids 6-17. I completed my internship and practicum at a rehab facility that worked with everything from trauma, substance use, and mood disorders. I work in the prison system for three years, two of which I was a substance abuse counselor. I have been running my own practice for just over two years now. I have a lot of experience working with a wide range of clients.

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.

Reaching out for help is a courageous first step—one you should be proud of.

I am a trauma-informed, Jungian-oriented psychotherapist with analytic training. My work is grounded in depth psychology and an understanding of how past experiences shape present patterns.

I specialize in personality disorders and am certified in this area, as well as in grief work. Anxiety, depression, and relationship challenges are often interconnected with these concerns and are an integral part of the work we do together.

I have experience with BIPOC, LGBTQIA+, women, disabilities, trauma, depression, and PTSD. My goal is to help you recognize your strengths and improve your self-compassion. I believe in the importance of the therapeutic relationship and strives to create an environment of trust, empathy, and unconditional positive regard.
