ADHD therapists and psychiatrists in Peoria, AZ

If you’re looking for support with PTSD, complex trauma, mood disorders, ADHD, personality disorders, self-harm, or suicidal thoughts, I want you to know you don’t have to carry it alone.

Since 2017, I’ve worked with clients ages 12+ in settings ranging from wilderness therapy and inpatient hospitalization to residential treatment and private practice. I also provide individual, family, and coparenting therapy.

Hello, my name is Sherri Crespin, a board-certified Psychiatric Mental Health Nurse Practitioner passionate about providing integrated care for complex mental health challenges, including personality disorders, PTSD and trauma, substance use disorders, ADHD, depression, anxiety, panic disorders, mood disorders, and bipolar conditions. My practice recognizes these conditions are interconnected in ways requiring specialized understanding.

I chose these specializations because I understand how trauma influences personality development, how ADHD complicates substance use recovery, how symptoms emerge during extreme stress, and how these complex interactions require providers who see the complete picture. Whether you're in recovery while managing other conditions, dealing with personality patterns that developed as survival mechanisms, or navigating multiple diagnoses, I bring the expertise needed for comprehensive care.

My approach emphasizes evidence-based treatments and the healing power of being truly understood. I recognize that seeking help for stigmatized conditions like personality disorders takes tremendous courage, especially after negative experiences with providers. I create a therapeutic space where you can explore your experiences without judgment or shame.

You can expect a thorough assessment, personalized treatment planning, and consistent support throughout our work together. My goal is to help you build resilience, develop effective coping strategies, and thrive in your daily life.

I believe healing happens through both stability and growth. I work with clients to navigate life’s challenges, build on their strengths, and develop practical tools to support coping, emotional well-being, and lasting change.

Outside of work, I enjoy spending time with my family, traveling, hiking, and cruising.

I'm accepting new patients in Arizona and California!

As a Board-Certified Psychiatric Mental Health Nurse Practitioner, I've dedicated my career to helping individuals find clarity and stability through compassionate, evidence-based medication management. My journey in mental health began with my foundational education at Mount Saint Joseph University, followed by advanced psychiatric training at Purdue Global, where I developed specialized expertise in psychopharmacology—the science of how psychiatric medications work in the brain and body.

I understand that starting or adjusting psychiatric medication can feel overwhelming. Many of my patients come to me after struggling with multiple providers, ineffective treatments, or confusing explanations about their care. I've made it my mission to change that experience. When we work together, you'll never wonder why I'm recommending a particular medication or what to expect from your treatment plan.

My clinical focus includes complex conditions that benefit from careful, individualized medication strategies: ADHD, OCD, personality disorders, PTSD and trauma-related conditions, depression, anxiety disorders, panic disorder, mood disorders, and bipolar disorder. I particularly enjoy working with patients who have treatment-resistant symptoms or multiple diagnoses—situations that require creative problem-solving and a deeper understanding of how medications interact within your unique system.

What sets my approach apart is the time I invest in truly understanding you. I'm here to provide clear guidance and consistent support throughout your journey toward better mental health.

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.

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.

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.
