Sometimes you can look like you're holding everything together while quietly feeling anxious, overwhelmed, or exhausted. You may spend so much energy taking care of work, family, or everyone around you that there's very little left for yourself. If that sounds familiar, you're not alone.

I work with adults navigating anxiety, ADHD, panic, trauma, relationship challenges, and major life transitions. My goal is to provide a warm, supportive space where you can slow down, better understand what's contributing to your stress, and build practical tools that help you feel calmer, more confident, and more connected to yourself.

I'm a board-certified psychiatric-mental health nurse practitioner with over 10+ of experience in the mental health field, and 3 years as a psychiatric mental health nurse practitioner. I founded Isimi Health & Wellness to provide thoughtful, evidence-based psychiatric care rooted in compassion, cultural humility, and a deep respect for the mind-body connection. My clinical background spans across PHP/IOP settings, Outpatient psychiatry, TMS, and telepsychiatry. I’ve worked with diverse populations experiencing anxiety, depression, trauma, mood disorders, and life transitions. Whether you're seeking support for mood instability, clarity around your medication options, or a space to reset and realign, I’m honored to walk alongside you on your wellness journey.

Hello, I’m Sherri Larson, an LCPC who is passionate about helping people feel grounded, understood, and supported. I’ve worked with individuals experiencing trauma, anxiety, depression, grief, and relationship difficulties, and I value the resilience people bring to therapy.

Often, struggles can become gateways to transformation. Many of the clients I work with are navigating low self-esteem, anxiety, depression, chronic stress, trauma, grief, or major life transitions that leave them feeling overwhelmed, stuck, or disconnected. You may be experiencing racing thoughts, emotional exhaustion, relationship difficulties, loss, or uncertainty about your direction in life. When we begin to explore these experiences with compassion and curiosity, new perspectives and meaningful change can emerge.

I believe telling your story in a safe, supportive space can be deeply healing. I want to hear about your hopes, dreams, challenges, and losses. My goal is to help you better understand your experiences, develop emotional resilience, and move toward greater clarity and self-acceptance. You are not alone, and I am here to walk alongside you as you move forward on your journey toward healing and growth.
