Hilda Ann Williamson, LCSW, helps individuals and families across California find healing, stability, and hope through compassionate, evidence-based care. She works with children, adolescents, and adults facing challenges such as anxiety, depression, trauma, grief, and life transitions. With over a decade of clinical experience, Hilda creates a warm and supportive environment where clients can safely explore their emotions, build resilience, and develop tools to improve their mental well-being.

At LifeStance Health, Hilda specializes in treating anxiety, depression, and trauma, helping clients overcome emotional distress and rediscover balance in their daily lives. She is experienced in guiding clients through major life changes—such as midlife or later-life transitions—and supports individuals coping with grief or medical conditions that impact their mental health. Her integrative approach draws on Cognitive Behavioral Therapy (CBT), mindfulness practices, and family therapy techniques, allowing her to tailor treatment to the unique needs of each person or family she serves.

Hilda has a deep passion for supporting children and adolescents, particularly those in foster care, adoption, or dealing with developmental challenges. She understands the profound effects that early experiences and family systems have on emotional growth. Through a compassionate and skillful approach, she helps youth and their caregivers strengthen relationships, improve communication, and navigate behavioral or emotional challenges with greater understanding and connection.

Her experience extends to working with diverse populations, including individuals with autism spectrum disorders, developmental disabilities, head injuries, and those within the LGBTQ+ community. Hilda’s goal is to provide a safe and affirming space where every client feels seen, valued, and empowered to grow.

Outside of her professional life, Hilda enjoys reading, listening to music, and swimming. She loves traveling and has visited countries such as the Netherlands, Hungary, and Australia. A devoted fan of college football, she appreciates the sense of excitement and community that the sport brings.
