Hello! I am Renell Kumeh, an advanced practice registered nurse, with dual certification in family medicine and psychiatry, licensed in OR, WA, DC, TX, FL, NV, ND, CT, MA and pending licensures in other states. At the core of my values is treating others the way I would like to be treated.

I'm Holly, a board-certified Psychiatric-Mental Health Nurse Practitioner with 23 years of clinical experience in psychiatric care and maternal-child health. This dual background has shaped how I see mental health: not as something separate from the rest of your life, but deeply woven into every transition, relationship, and challenge you face. My work taught me that women's mental health—especially during pregnancy, postpartum, and hormonal transitions—requires specialized understanding and individualized care.

I provide comprehensive psychiatric treatment for adults across a broad spectrum of conditions: perinatal mood and anxiety disorders, OCD, PTSD and trauma-related disorders, personality disorders, depression, anxiety, panic disorder, bipolar disorder, and schizophrenia spectrum conditions. I have particular expertise in women's mental health throughout the reproductive years, though I welcome anyone seeking compassionate, evidence-based care.

My approach is straightforward: effective treatment should fit your real life. I combine psychiatric interventions—including medication management when appropriate—with practical therapeutic strategies and lifestyle modifications that actually work for you. I'll help you understand what's happening, why it's happening, and what options make sense for your unique situation.

What matters most to me is seeing you as a whole person—not just a diagnosis. You have strengths, values, relationships, and goals that deserve attention alongside your symptoms. Whether you're managing a long-standing condition, processing trauma, navigating major life changes, or simply seeking better balance, you deserve a provider who recognizes your potential and partners with you toward sustainable wellness.

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.
