Anxiety and depression therapists and psychiatrists in Fullerton, CA

Hello and welcome!

As a licensed clinical social worker, I truly believe that mental health is the foundation for growth and healing. It takes courage and strength to take that first step and I want to celebrate you for making it!

I mainly work with adults in individual therapy, drawing from various modalities tailored to each person's unique needs and issues. I'm also certified in EMDR, which can be really helpful for processing difficult experiences.

I am a clinical psychologist licensed in California and Illinois, and can see clients from both states. I have worked with clients in the areas of depression, anxiety, relationships issues, addictions, stress management, sport and performance, bipolar disorder, and binge eating disorder. My therapy style is personable, connected, focused, and attuned.

As a Nurse Practitioner, I believe healthcare should be a partnership, not a prescription. My approach combines advanced clinical skills with a deep commitment to patient advocacy, ensuring every individual has the tools and confidence to take charge of their health. I specialize in creating personalized treatment plans that honor the whole person — mind, body, and spirit. Whether I’m diagnosing, prescribing, or simply listening, my mission is to make every patient feel seen, heard, and cared for. I strive to turn sessions into moments of trust, learning, and hope."

I am board certified in Family Practice as well as Psychiatry and have been in practice for 25 year. I work with mental health issues such as depression, anxiety, sleep disorders, bipolar disorder, as well as address physical symptoms or issues that may affect mental health. I hold a Doctorate degree in education and Master Degrees in Advance Practice Nursing and education.

Welcome. I'm Roxy, dedicated to helping you find what you are looking for in therapy. My goal is to offer a safe, compassionate space where you can heal and grow.

Hello, my name is Alexander Valenzuela PMHNP. I specialize in psychiatric medication management and cognitive behavioral talk therapy. If you're struggling with your mental health and realize you want help, you don't have to do it alone. I am looking forward to starting the journey with you to help achieve your best self.

I hold a Master’s degree in Clinical Psychology from Antioch University, Santa Barbara, California. My practice blends both psychological approach as well as eastern wisdom. With a diverse background of professional and life experiences, I bring empathy, warmth, and a solution-focused mindset to my clients. My goal is to help clients alleviate suffering, boost their productivitiy, and enhance well-being.

If you're feeling overwhelmed, stuck, or unsure how to move forward, you don't have to figure it out alone.

I help adults work through anxiety, ADHD, depression, and the stress of big life transitions so you can move forward with more clarity, confidence, and a renewed sense of direction.

I'm a Licensed Professional Clinical Counselor with over a decade of clinical experience, and I bring a calm, grounded presence to the work.

My background spans trauma-informed care, support for college students building self-advocacy and success strategies (especially those with learning differences), and extensive work with the military community — including wounded warriors and their families.

Whether you're navigating a career or life change, managing attention or focus challenges, working through anxiety or depression, or facing relationship stress, I offer a safe, collaborative space where real growth is possible.

Clients often describe me as warm, real, non-judgmental, and direct in a supportive way. I'm LGBTQIA+ affirming and welcome people from all backgrounds with a spirit of inclusion and care.

As a Psychiatric Mental Health Nurse Practitioner, I aim to create a space where you feel heard, respected, and understood. I believe mental health care should be collaborative, practical, and tailored to your unique needs. My approach combines evidence-based treatment with real-life understanding whether that includes therapy, lifestyle changes, or medication management when appropriate. I value honesty, cultural awareness, and meeting you where you are. My goal is to help you feel more stable, confident, and in control of your mental health not just during appointments, but in your everyday life.

I’m Maria, and I am a Licensed Marriage and Family Therapist with over twelve years of experience working with families, children, and adults. My work has focused on breaking generational cycles of trauma and navigating challenging life transitions. In my work I have supported individuals and families through growing up, raising their children, and bringing healing and harmony into the home. I am deeply passionate about helping others on their journeys toward personal growth and a better quality of life and consider it a gift to be an agent of change.

In addition to my clinical work, I am also a working mother of a college student and clinically supervise and train other clinicians. This experience gives me a unique perspective and understanding on navigating life transitions and balancing multiple roles.

My approach is warm, affirmative, and solution-oriented – with some humor mixed in. While it can feel intimidating to take that first step, if you are ready, I can guide you in finding areas of strength while also challenging areas for growth in a compassionate way. Together we can work toward healing in a safe environment and create positive change to improve your quality of life.
