Ashleigh provides thoughtful, evidence-based psychiatric care for children, adolescents, and adults, with an emphasis on careful assessment, conservative treatment planning, and collaboration.

As a Board-Certified Psychiatric Mental Health Nurse Practitioner with over a decade of clinical experience, I bring something distinctive to mental health care: a research-informed approach grounded in real-world compassion. My background as a Sub-Investigator in psychiatric trials keeps me current with the latest treatment innovations, while my Master's from Western University of Health Sciences and ongoing Doctoral studies ensure I'm always expanding my expertise.
I specialize in the conditions that require specialized understanding: ADHD, autism, complex patients, OCD, personality disorders, PTSD/trauma, schizophrenia/psychosis disorders, and substance use disorders, alongside comprehensive treatment for depression, anxiety, panic, mood disorders, and bipolar disorder. What excites me about this work is that every client teaches me something new about resilience and recovery.
My clinical experience spans diverse settings, from outpatient care to cutting-edge research, giving me a unique perspective on evidence-based treatment. I combine thorough psychiatric evaluations using DSM-5 criteria with personalized medication management, always staying current with the latest advances in psychiatric care.
What I want you to know is this: your mental health journey matters to me both professionally and personally. I'm committed to providing care that's not just clinically excellent, but deeply respectful of your individual experience and goals.
I am a board-certified Psychiatric Mental Health Nurse Practitioner specializing in care across the lifespan treating clients with ADHD, anxiety, bipolar disorder, depression, OCD, PTSD and sleep disorders. I am committed to delivering high-quality, compassionate care tailored to each patient’s unique needs. I am a proud veteran.
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, schizophrenia and psychosis disorders, 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 psychotic 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 or psychosis 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.
