Obsessive-compulsive disorder therapists & psychiatrists in West Covina, CA

Hi, I'm Cassie (Cassandra), a board certified Psychiatric Mental Health Nurse Practitioner with over five years of experience in mental health care.

I believe mental health treatment should feel supportive, collaborative, and free of judgment. Every person has a unique story, and I take the time to listen, understand your goals, and create a treatment plan tailored to your individual needs.

I specialize in the treatment of anxiety, depression, ADHD, stress, burnout, sleep concerns, and other common mental health conditions. Through thoughtful psychiatric evaluation and medication management, my goal is to help you find clarity, restore balance, and move forward with confidence.

Whether you are seeking support for the first time or looking for a fresh approach to your mental health care, I strive to provide a comfortable and welcoming space where you feel heard, respected, and supported.

I look forward to partnering with you on your journey toward improved mental wellness and helping you build the tools needed to thrive in everyday life.

Do you ever feel a heaviness in the background of your life, even if you’re not exactly sure where it’s coming from? Maybe certain patterns or challenges keep repeating, no matter how much effort you put into moving forward, and you’re beginning to wonder what’s underneath it all. In our work together, we’ll explore those experiences with curiosity and care. I’ll be there to support you in deepening your self-awareness, uncovering what’s holding you back, and making meaningful changes that align with who you are and what you want.

Great to meet you! Taking the first step toward caring for your mental health can feel overwhelming, so I'm glad you're here. I'm a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over 1 years of experience helping adolescents and adults navigate anxiety, depression, ADHD, bipolar disorder, trauma, and other mental health concerns. My approach is compassionate, collaborative, and personalized, and I strive to create a safe, judgment-free space where you feel heard, supported, and empowered to reach your goals.

Do you feel like something is wrong with you? Do you wish it would all just stop and go away? Is your child acting out and you don't know why or what to do? If you have had any of these thoughts, then you're in the right place! My practice is based around what happened to us, not what is wrong with us. I am here to support & guide you in processing thoughts and feelings, reflect on experiences, learn new coping skills, and figure out next steps. I will listen, teach, brainstorm, guide and help you build tools to meet your goals.

I’m a naturally curious, growth-oriented human who believes healing happens when insight meets action. I love helping people zoom out to see the bigger picture of their lives—while also gently zooming in on the patterns, habits, and beliefs that shape their everyday experience.

I’m drawn to the intersection of self-awareness and real-world momentum. Therapy with me is thoughtful, collaborative, and grounded. We can explore the deep stuff—identity, relationships, purpose, transitions—while also building practical tools you can actually use on a Tuesday afternoon when life is lifing.

I value emotional honesty, nervous system regulation, and sustainable growth over quick fixes. I believe you’re not broken—you’re adaptive. Together, we figure out what’s working, what’s outdated, and how to move forward in a way that feels aligned, empowered, and authentically you.

Expect warmth, insight, humor when it fits, and a space where all parts of you are welcome. Healing doesn’t have to be clinical and cold—it can be connected, intentional, and even a little energizing.

I’m David Cao, a board-certified Psychiatric Mental Health Nurse Practitioner providing online psychiatric evaluation and medication management for adults throughout California. I especially enjoy working with young adults dealing with anxiety, depression, stress, overthinking, or feeling overwhelmed.

If reaching out for psychiatric care feels intimidating, my goal is to make the process feel approachable. My style is calm, laid-back, and collaborative. Our sessions are more like conversations than interrogations, and I want you to feel comfortable being yourself. I’ll be there for the difficult conversations, celebrate the small wins with you, and make room for a little humor along the way.

With over 7 years of experience in mental health care, I understand how difficult it can be to balance everyday responsibilities while struggling with your mental health.

I work well with anyone who seeks therapy and is ready to work on themselves. I have worked with about every population, culture and age group. Issues that I am best suited to treating include a wide variety of disorders, childhood trauma, addictions, domestic violence, parenting/bonding/interpersonal relationships. I certified in EMDR and expressive arts therapy. I like to offer different forms of expression to my clients in the healing arts. I also give plenty of skill building tools and homework so clients can maximize their progress outside of the weekly sessions. I speak Spanish fluently.
