Obsessive-compulsive disorder therapists & psychiatrists in Petaluma, CA

Hi, I’m Eliza Rivera-Mitu, a board-certified Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner. I specialize in treating ADHD, anxiety, depression, and mood disorders, as well as the psychiatric challenges in autism. With a background in both psychiatry and family medicine, I take a holistic approach that considers the whole person—not just the diagnosis. I'm passionate about helping you feel heard, empowered, and supported in your mental health journey.

I am a Psychologist who is passionate about helping women through life transitions and reproductive challenges, including pregnancy, motherhood, infertility, loss and trauma.

Hello! I provide psychiatric evaluations and medication management for children (6+), teens, adults, and seniors. Life can feel overwhelming when anxiety, depression, ADHD, or bipolar mood swings affect your energy, focus, relationships, and daily life. I believe mental health care should feel supportive, comfortable, and personalized. As a board-certified PMHNP with over five years of experience, I help individuals struggling with anxiety, depression, ADHD, autism, bipolar disorder, OCD, PTSD, eating disorders, schizophrenia, and other mental health concerns.

I take a warm, empathetic, and direct approach to working my clients. I believe that people can be incredibly resilient when they put their minds to it. Together, we can tap into your potential to strengthen your competence and tackle your goals. I will fight for you to rid yourself of unhelpful patterns and narrow the gap to the life you desire.

Hi! I’m Camille. Thank you for being here. For more than 15 years, I’ve had the privilege of caring for individuals and families across many different healthcare settings—from emergency nursing and the COVID-19 pandemic response to travel and concierge nursing, Intensive Outpatient Programs (IOP), Partial Hospitalization Programs (PHP), and outpatient psychiatry. After years of living and working in major cities, including New York and Los Angeles, I eventually found my way to California’s Sierra Nevada foothills. My own experiences shape the way I connect with people. I’m a mother, a first-generation immigrant, part of a multicultural family, and a member of a rural mountain community. A meaningful part of my work is with high-achieving adults—professionals, executives, graduate students, entrepreneurs, healthcare workers, and others who may appear to be doing well by every external measure while privately feeling overwhelmed, disconnected, burned out, or simply not quite like themselves. I also understand the unique weight that can come with intergenerational expectations, cultural identity, and learning to navigate more than one world at once.
