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.

I am a clinical psychologist licensed in California and Illinois, and can see clients from both states. I have worked with clients in the areas of depression, anxiety, relationships issues, addictions, stress management, sport and performance, bipolar disorder, and binge eating disorder. My therapy style is personable, connected, focused, and attuned.

I'm Sherri Crespin, a board-certified Psychiatric Mental Health Nurse Practitioner specializing in complex mental health conditions in adults. With dual board certifications from the American Nurses Credentialing Center as both a Family Nurse Practitioner and Psychiatric/Mental Health Nurse Practitioner, I bring a comprehensive understanding of how mental and physical health intersect to create truly holistic care.

My clinical expertise includes treating trauma and PTSD, personality disorders, substance use disorders, and mood disorders such as depression, anxiety, panic disorder, and bipolar disorder. I'm experienced in managing complex medication regimens and other specialized treatments that require careful monitoring and expertise.

I earned both my Bachelor of Nursing and Master of Science in Nursing from the University of Texas at Austin, where I developed a strong foundation in evidence-based practice. What sets my practice apart is my commitment to treating the whole person—not just managing symptoms, but understanding your unique story, challenges, and goals.

Whether you're seeking psychiatric medication management or comprehensive treatment for multiple conditions, I create a safe, non-judgmental environment where you can openly discuss your concerns and actively shape your treatment plan. I also provide ESA letters when clinically appropriate.

I look forward to partnering with you on your journey toward improved mental health and lasting well-being.

Xin chào! I am a relationally-oriented Jungian depth psychotherapist with degrees from Pacifica Graduate Institute. I enjoy working with creatives, students of psychotherapy, and those dedicated to a life oriented toward meaningfulness.

As a therapist I'm here for you. It seems brave to me make a decision to come to therapy. My part is to listen and without judgment or personal agenda and to be effective in your needs and wants. Of course, I also need to be aware of the legals and ethicals of therapy. I attended Sarah Lawrence College and Harvard University for my BA, and Phillips Graduate Institute for my MA.
