Addiction therapists & psychiatrists in Garden Grove, CA

I have 15+ years of experience working with individuals and couples who have experienced trauma, both directly and indirectly. My specialty is those going through a loss, suffered emotional trauma, or are victims of violence. Unaddressed individual trauma can often lead to anxiety, depression and difficulties in developing / maintaining loving relationships. Couples can struggle with unhealthy patterns of communication and need alternative tools to better understand each other. With a warm, collaborative, and evidence-based approach I support clients facing issues such as anxiety, grief, life changes and relationship challenges.

I am a Psychiatric Mental Health Nurse Practitioner (PMHNP) who provides compassionate, evidence-based care for adults. My approach is clinical, trauma-informed, and whole-person, meaning I look beyond symptoms alone and consider the many parts of life that shape mental health. I believe care should feel collaborative and supportive, not overwhelming. My goal is to help you feel understood while creating a treatment plan that fits your life, values, and goals. Whether you are seeking medication management, in-office IV or IM ketamine treatment, or support through a difficult season, I want you to feel safe, respected, and empowered.

I am a licensed clinical psychologist (PsyD) with extensive experience working in residential treatment, sober living, and private practice settings since 2010. My career began as an intern in an eating disorder residential program, later expanding into adolescent dual-diagnosis treatment. Alongside completing my doctorate in clinical psychology, I launched my private practice, where I continue to work with clients through Telehealth. Currently, I also work in a sober living facility, supporting adults facing addiction and co-occurring mental health challenges.

I'm Stephanie Patrick-Calvillo, a Board-Certified Psychiatric Mental Health Nurse Practitioner who believes mental health care should be accessible, compassionate, and tailored to each individual. Over the past 15+ years, I've worked with diverse populations—from adolescents facing their first mental health crisis to adults navigating complex psychiatric conditions, and seniors experiencing cognitive and emotional challenges.

My practice is grounded in the belief that effective treatment goes beyond symptom management. I take time to understand your unique story, your strengths, and the factors that shape your mental health. Whether you're dealing with a new diagnosis or have been managing symptoms for years, I meet you where you are with respect and without judgment.

I specialize in treating mood disorders, anxiety, psychotic disorders, personality disorders, substance use concerns, and behavioral issues related to dementia. I've completed advanced certification training because I'm committed to staying current with evidence-based treatments—ensuring you receive care that reflects the latest research.

Beyond clinical work, I'm passionate about mentoring the next generation of healthcare providers. I've mentored nursing and nurse practitioner students from multiple universities, which keeps me grounded and reminds me why this work matters.

When you work with me, you're getting someone who genuinely cares, who's seen mental health challenges from many angles, and who believes deeply in your capacity for healing and growth.
