I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a DNP (Doctor of Nursing Practice) degree from the University of Massachusetts Global. I have experience working with adolescents and adults in multiple settings facing various complex mental health issues, including OCD, depression, anxiety, ADHD and mood disorders.
I am an integrative clinician providing psychotherapy, coaching, and mindful medication management to support meaningful and lasting change. I am also a board-certified Psychiatric Mental Health Nurse Practitioner with a Master’s from UCSF (2018), where I trained at Langley Porter Psychiatric Hospital and Clinics. Additionally, I hold a Sociology degree from Dartmouth College and have completed advanced training through the Psychedelic Therapies & Research Certificate at CIIS, coursework at the San Francisco Psychoanalytic Psychotherapy Training Program, and foundational studies in energy medicine at the Academy of Intuition Medicine. I continue to refine my work through ongoing psychoanalytic supervision.
Mental health and physical health impact each other profoundly. I have a keen understanding of that with years of experience as a Psychiatric Mental Health Nurse Practitioner and a Family Nurse Practitioner at the same time. I specialize in depressive, mood, anxiety disorders, and ADHD. I am fascinated with integrative medicine and oriental philosophy and their utility in current evidence-based psychotherapy.
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.

Hi, and welcome! I am happy you are here to explore my offerings and a return to your wellbeing. A bit about me:
I am a board-certified, doctorally prepared Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over 17 years of experience spanning acute care, crisis response, psychiatric nursing, and public health. I offer integrative psychiatric care that blends evidence-based medicine with holistic, trauma-informed approaches. I work with adolescents, adults, and older adults navigating depression, anxiety, mood disorders, ADHD, trauma, grief, life transitions, and healthcare-related burnout.
Our work together will feel collaborative, grounded, and deeply respectful of your story. You can expect a therapeutic relationship rooted in listening, presence, and curiosity—where your values and goals shape the course of treatment. I aim to create a safe space where you feel seen, supported, and empowered to heal and thrive.
Outside of work, I love being active in nature, dancing, traveling, cooking, and spending time with my friends, family, and my beloved dog.
