Obsessive-compulsive disorder therapists & psychiatrists in Simi Valley, CA

I'm Sinat Aleje, a board-certified Psychiatric Nurse Practitioner with over ten years of experience in the mental health field. I’ve had the privilege of working with individuals across a variety of clinical settings, which has deepened my understanding of the emotional, psychological, and social challenges people face. I specialize in treating adults and adolescents with anxiety, depression, ADHD, PTSD, OCD, bipolar disorder, and schizoaffective disorder.

Clients often tell me they feel truly seen and heard during our sessions. I strive to create a safe and supportive space where healing can begin, and where clients are empowered to take an active role in their care. I hold a Doctor of Nursing Practice (DNP) and am committed to providing high-quality, evidence-based care that evolves with your journey.

If you're looking for a thoughtful, collaborative partner in your mental health care, I’d be honored to work with you.

I am a Board Certified Psychiatric Mental Health Nurse Practitioner who provides compassionate, patient-centered, and evidence-based care. I strive to create a safe, nonjudgmental space where you feel heard and supported. Together, we develop personalized treatment plans focused on your goals, well-being, and long-term mental health.

You don't have to arrive here put together. Whatever you're carrying right now belongs in this space: anxiety, grief, relationship stress, a shifting sense of who you are, or something you haven't quite found words for yet. I work with adults and older adults navigating the full range of what life brings, with a particular passion for supporting BIPOC and LGBTQIA+ communities and people who are questioning or deconstructing their faith. My work spans trauma, identity, women's issues, OCD, depression, and the anger or sadness that accumulates when you've been holding too much for too long.

I’m a psychiatrist who practices from a psychodynamic perspective, with attention to emotional depth, meaning, and the ways our histories shape how we experience ourselves and others. My work focuses on understanding symptoms in context — as expressions of what is happening within your mind, your relationships, and our society.

Hi, I'm Evelyn! As a seasoned psychiatric nurse practitioner with over four years of experience, I'm passionate about helping children, teens, and adults navigate their mental health journeys with compassion and understanding.

I believe everyone deserves to feel heard and empowered in their healing process. Through my work with diverse populations—from children as young as six to adults with complex mental health challenges—I've learned the importance of meeting patients exactly where they are, without judgment and with genuine care.

I specialize in ADHD assessment, medication management, and coaching across all ages. Having witnessed how ADHD impacts every aspect of life, I take a comprehensive approach beyond medication. I help families understand ADHD systems, develop coping strategies, and create academic accommodations for success.

My experience includes managing complex psychiatric conditions and treatment-refractory illnesses requiring specialized medications like lithium and dual-antipsychotic treatments. I believe in holistic care, emphasizing how nutrition, physical activity, mindful practices, and sleep hygiene support mental wellness alongside medication.

What sets my practice apart is collaborative care. I work closely with patients and families to create individualized, achievable treatment goals. Whether addressing anxiety, depression, ADHD, or other conditions, I prioritize building therapeutic relationships where you feel safe sharing your experiences.

I maintain high standards with comprehensive malpractice insurance, current California licensure, and DEA certification. My approach includes medication monitoring and regular prescription checks for your safety.

My practice is built on the foundation that everyone deserves compassionate, personalized mental health care. I look forward to partnering with you to achieve the balance and peace you're seeking.

Chenda Dyck is a licensed Marriage and Family Therapist. She's in the final stretch of her PhD in Marital and Family Therapy, and she finished her master's at Fresno State back in 2016.

Chenda was born in Ratanakiri, in Cambodia's northern highlands. Families there hold together through a lot, and she watched how that works long before she had any language for it. She arrived in the U.S. in 2003, sponsored by an adoptive American family. What she learned in those years is the thing she still builds her practice on — that one safe relationship can redirect an entire life.

Her work centers on Emotionally Focused Family Therapy (EFFT), grounded in systemic and attachment theory and carried by a social-justice lens. Diverse, multiracial, and immigrant families are where she does her best work — families managing cultural pressure and emotional strain at once. In session and in supervision, she holds to the same standards: respect for culture, honesty about feelings, and the relationship kept at the center.

Hi, I’m Tina Chen, a Psychiatric Mental Health Nurse Practitioner dedicated to helping clients feel their best. I specialize in treating depression, anxiety, and ADHD, and I combine medication management with practical tools from CBT and positive psychology. With advanced training from California Baptist University and National University, I focus on creating a supportive, collaborative space where you can build confidence, resilience, and balance in your everyday life.

For the past year, I've worked with adults facing serious mental health challenges at one of Los Angeles's largest public health systems, and what I've learned is that lasting change comes from relationships built on trust. Now I'm bringing that experience into private practice, where I can focus on what matters most: your individual progress. I work with people navigating anxiety, depression, and PTSD, and I offer flexible evening and weekend availability via telehealth throughout California. As a PMHNP, I'm here to support your whole mental health journey.

My name is Karen and I have been working in mental health for 25 years. It is rewarding to witness my clients take charge of their lives and connect them to what they find most meaningful. Whether it’s listening, teaching new skills, or offering constructive feedback, I work closely with each person so they can find more joy in life.

I work with teens, young adults, and families navigating ADHD, anxiety, depression, substance use, identity exploration, family conflict, relationship challenges, life transitions, and emotional overwhelm. Whether you're feeling stuck, disconnected, overwhelmed, or uncertain about what comes next, therapy can provide a space to better understand yourself and move toward meaningful change.

My approach is warm, collaborative, and nonjudgmental. I believe therapy works best when clients feel genuinely understood, supported, and accepted for who they are. Together, we build on strengths, develop practical coping skills, and explore the patterns that may be getting in the way of living a more fulfilling life.

I strive to create a safe and supportive environment where clients can be honest, reflective, and fully themselves without fear of judgment. My goal is not only to help clients navigate current challenges but also to foster greater resilience, self-awareness, confidence, and connection.
