Obsessive-compulsive disorder therapists & psychiatrists in Hawaii

Welcome — I'm so glad you're here. I'm David Guo, a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) serving clients throughout Honolulu and across all of Hawaii via secure telehealth. Whether you're in Downtown Honolulu or on Maui, Molokai, Kauai, or the Big Island, I'm here to support you. I believe real healing starts with real connection. That means taking time to truly know you — your story, your life, your goals — so you never feel like just a chart. You won't feel rushed here. I'm available weekdays (evenings too) and weekends.

Are you feeling anxious, stressed, or just need someone to talk to? You've come to the right place. Throughout our lifetime, we are faced with many challenges, barriers, and successes that can all have their own level of overwhelmingness and joy. Whatever you are going through, let's work through it together.

My name is Christine Keanu and I am a Licensed Clinical Social Worker (LCSW). I earned my Master of Social Work Degree from the University of Hawaii at Manoa. I have a professional background working with children, families, and individuals involved in a wide range of social service systems. My work has included supporting clients through complex life experiences, stressors, and transitions, often in settings where safety, trust and consistency are especially important.

I am open, approachable, and committed to listening carefully to your experiences without judgment. I believe that each person carries a unique story, and my goal is to provide a supportive space where you feel heard, understood, and encouraged as you navigate life’s challenges and opportunities for growth. Together, we can explore what is most important to you and work toward creating a life that feels meaningful, authentic, and aligned with your values.

My background includes earning a Ph.D. from the University of California, Berkeley, along with a lifelong appreciation for personal growth, nature, and the healing power of connection. Growing up learning to surf fostered a deep respect for the ocean and the lessons it offers about resilience, balance, and adapting to life's changing conditions. These experiences have shaped my belief in the importance of honoring each individual’s journey and recognizing that growth often comes through both challenge and reflection.

My career began in 1997 as an AmeriCorps member working in harm reduction during the peak of new HIV infections. Since then, I've held many roles as a proud social worker. I have been a therapist for 18 years, with extensive training & experience in harm reduction therapy, Motivational Interviewing, Cognitive Behavioral Therapy, and Cognitive Processing Therapy for PTSD. I have lived experience with mental health challenges and treatment

I have worked and lived in:

• Charlotte, NC
• San Francisco
• Michigan
• Oahu, Hawaii

I currently accept individual adult clients only through Headway. I do not provide couples or family therapy through this platform at this time.

I am a licensed Marriage and Family Therapist who works with individuals, couples, and LGBTQ+ clients seeking deeper self-understanding, emotional healing, and more connected relationships. My approach is warm, relational, trauma-informed, and grounded in the belief that healing happens through safety, honesty, and meaningful connection.

I specialize in relationship therapy, anxiety, depression, identity exploration, attachment wounds, complex trauma, and psychedelic assisted psychotherapy. I also support clients navigating life transitions, grief, shame, self-worth, communication challenges, and patterns that keep them feeling stuck or disconnected from themselves and others.

My work draws from Emotionally Focused Therapy, the Gottman Method, Internal Family Systems, somatic awareness, humanistic and existential therapy, and trauma-informed care. I help clients slow down, listen inward, understand their patterns, and develop more compassionate and empowered ways of relating.

As a queer-affirming therapist, I am especially passionate about supporting LGBTQ+ clients and relationships. I strive to create a space where clients can bring their full selves—without judgment—and explore healing in a way that honors their identities, histories, relationships, spirituality, and lived experience.

Living in Hawai‘i offers so much beauty—but that doesn’t mean life always feels peaceful. Whether you’re navigating anxiety, depression, trauma, ADHD, or other mental health challenges, you don’t have to do it alone. I work with adults and teens to help them move toward healing, balance, and lasting change.
