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.
Clinical Focus & Services
I provide pharmacotherapy (medication management) motivational interviewing, and other therapeutic modalities. We can assess during the first meeting if your treatment requires additional therapeutic support. I will provide a referral to a licensed therapist to ensure you receive comprehensive care. My practice supports:
Early morning, evening, and weekend appointments are available. Contact the office directly to find a time that works for you.
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'm Holly, a board-certified Psychiatric-Mental Health Nurse Practitioner with 23 years of clinical experience in psychiatric care and maternal-child health. This dual background has shaped how I see mental health: not as something separate from the rest of your life, but deeply woven into every transition, relationship, and challenge you face. My work taught me that women's mental health—especially during pregnancy, postpartum, and hormonal transitions—requires specialized understanding and individualized care.
I provide comprehensive psychiatric treatment for adults across a broad spectrum of conditions: perinatal mood and anxiety disorders, OCD, PTSD and trauma-related disorders, personality disorders, depression, anxiety, panic disorder, bipolar disorder, and schizophrenia spectrum conditions. I have particular expertise in women's mental health throughout the reproductive years, though I welcome anyone seeking compassionate, evidence-based care.
My approach is straightforward: effective treatment should fit your real life. I combine psychiatric interventions—including medication management when appropriate—with practical therapeutic strategies and lifestyle modifications that actually work for you. I'll help you understand what's happening, why it's happening, and what options make sense for your unique situation.
What matters most to me is seeing you as a whole person—not just a diagnosis. You have strengths, values, relationships, and goals that deserve attention alongside your symptoms. Whether you're managing a long-standing condition, processing trauma, navigating major life changes, or simply seeking better balance, you deserve a provider who recognizes your potential and partners with you toward sustainable wellness.
I am a dual board-certified nurse practitioner. I graduated with my Family NP at Grand Canyon University in 2018.I graduated with my post-graduate cert as a Psychiatric Mental Nurse Practitioner at Wilkes University in 2022.I am constantly looking forward to continue my education to better serve my patients and to ensure that I am up-to-date with the latest advances in the fields of medicine and psychiatry.You will be treated with holistic care that combines traditional and alternative medicine.
