Clients often describe therapy with me as grounding, validating, and clarifying. I provide a space where you don’t have to perform, explain yourself away, or have everything figured out.

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

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.

Hello! I'm Keeley Estrada, LMFT. I am passionate about supporting my clients in connecting with themselves and what truly matters to them. I understand the importance of having a therapist who gets you and what you are going through.

I completed my masters in marriage and family therapy at USC and bachelors in psychology at SJSU. I have experience working in all levels of care including private practice, community mental health agencies, intensive outpatient, and partial hospitalization.

I believe that meaningful mental health care starts with trust, compassion, and genuine connection. Over the past 15 years, I have worked across a variety of healthcare settings, including trauma nursing, emergency nursing, and nurse leadership roles, caring for individuals and families during some of life's most challenging moments. These experiences have reinforced my belief that every person deserves to be treated with dignity, empathy, and respect.

My commitment to mental health care is also shaped by personal experience. Like many people, I have witnessed the impact of mental health challenges in my own life and among loved ones, which has deepened my understanding of the courage it takes to seek help. I strive to create a welcoming, judgment-free space where clients feel comfortable discussing difficult thoughts, emotions, and life experiences.

I'm a bilingual/bi-cultural Licensed Marriage & Family Therapist in CA, w/ 9y of clinical experience. I've treated children, at-risk adolescents, adults and families in various settings, such as: in-home, school-based (k-12), telehealth, pediatric clinic & private practice. My therapeutic experiences are working with individuals to resolve symptoms including, but not limited to: anxiety, depression, ADHD, behavioral issues, divorce, relationships, grief, self-esteem, trauma, & family conflicts.

Clients often come to me with concerns about how to deal with microaggression, intersectional identities, burnout, communication concerns, family dynamics, perfectionism, self-critical thoughts, imposter syndrome, stress, trauma, anxiety, grief and loss. I support my clients through life transitions, relationship distress, self-critical thoughts, shame, grief, intersectional identities, and trauma.

Working with me, many clients report letting go of people pleasing, imperfections, expectations, shame, anxiety, carrying other people's burdens, having to regulate for others, self-critical thoughts, grief, loss, releasing old family patterns and wounds, and personalizing. Many clients say they have more capacity for joy, gratefulness, better communication skills within their lives, better boundaries, more self-compassion and grace, going after opportunities, better self-care, learning to advocate for themselves, more grounding and emotional regulation, and confidence.

I specialize in working with BIPOC women and men, activists, and healthcare workers.
