You are the one everyone relies on - the strong one. Even when you’re running on empty, you keep showing up, holding it together, and pushing through. On the outside, you look composed. Inside, you might feel exhausted, unseen, or detached from yourself. I work with adults break free from patterns that keep them stuck in survival mode. We will work on reconnecting with your needs, rebuilding self trust, and creating a balanced, authentic relationship with yourself. I bring a compassionate, steady presence to therapy; no cold stares or awkward silences. Just a real human connection, where you can feel safe enough to show up. As a therapist for the past 9 years and someone who has navigated my own share of life’s complexities, I understand the invisible weight we often carry; anxiety, depression, expectations, and the pressure to hold everything together.

Choosing the right therapist is important, so I offer a free 15-20 minute phone or video consultation to discuss your needs and ensure we’re a good fit. There’s no pressure; this call is simply an opportunity for you to learn more and decide if you’d like to move forward with therapy. You may take your time after the call to decide whether to move forward.

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 strive to create a safe, nonjudgmental space where you feel heard and supported. Together, we develop personalized treatment plans focused on your goals, well-being, and long-term mental health.

Something positive, warm, and uplifting about me as your PMHNP is that I genuinely believe in your strength and resilience. I see your potential for growth and healing, even during the toughest of times. Together, we'll navigate through the challenges.

I have found my own personal healing to be intimately connected to nature, and it is here that I believe that we can all begin to rediscover our intrinsic humanity and let go of those things that distract us from our higher selves. In my spare time, I work as an outdoor educator and manage my own private practice and guide Outdoor Retreats

I believe it is helpful and important to translate what is discussed in session and in telehealth meetings into lived experience and real change.
