As a PMHNP-BC who specializes in autism, complex cases, OCD, personality disorders, PTSD/trauma, schizophrenia/psychosis disorders, and substance use, I've built my practice around understanding that every person's mental health journey is unique—especially when multiple conditions interact or when traditional approaches haven't worked.

I also provide comprehensive treatment for depression, anxiety, panic disorders, mood disorders, and bipolar disorder, always with an understanding that these conditions often overlap and influence each other in complex ways. What I want you to know is this: your experiences are valid, your struggles make sense in the context of your life, and there's no such thing as being "too much" for treatment.

Whether you're masking autistic traits, battling compulsive behaviors, managing intense emotions, processing trauma, questioning reality, or struggling with substances, I meet you exactly where you are without trying to force you into a predetermined mold. My approach combines evidence-based treatments with deep respect for your individual needs and experiences.

You deserve a provider who doesn't see complexity as a problem to solve, but as a roadmap to understanding how to best support your unique path to wellness.

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'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.
