Cailyn Hymer-Costa , LCSW

Cailyn Hymer-Costa is a Licensed Clinical Social Worker (LCSW) practicing in California. The LCSW credential denotes advanced clinical training in social work and the ability to provide therapeutic care; her license number is CA LCSW 127024. With five years of experience, she centers her practice on compassion, empathy, and authenticity, offering a calm, nonjudgmental space where people can explore emotions, build resilience, and learn practical strategies to reduce stress and manage life’s challenges.

She has supported individuals facing anxiety, depression, trauma, and substance use disorders, and she addresses eating and food-related concerns as well as body image and self-love. A significant focus of her work is perinatal mental health - supporting people through pregnancy, the postpartum period, and early parenthood. She helps clients navigate prenatal anxiety, postpartum depression, shifting identity as they become a parent, and the day-to-day overwhelm that can accompany those transitions.

Cailyn draws on evidence-based therapeutic techniques to tailor care to each person’s needs, blending practical skill-building with a respectful, collaborative stance. Her approach aims to help clients process difficult feelings, strengthen coping skills, and move toward sustainable change at a pace that feels right for them.

Evidence-Based Techniques and Flexible Online Support

Many of Cailyn’s sessions use practical, skills-based techniques that teach stress reduction, emotion regulation, and coping strategies. These approaches focus on present-day challenges and help clients develop tools to manage anxiety, depressive symptoms, and everyday overwhelm.

She also offers more exploratory, insight-oriented work that helps clients examine thoughts, patterns, and shifts in identity - work that is often helpful during pregnancy, the postpartum period, and life transitions into parenthood. In addition, her practice addresses addiction and eating-related concerns with structured approaches that emphasize behavioral changes and relapse prevention.

Finding the right therapeutic approach is a collaborative process. Cailyn works with each person to identify goals, preferences, and needs, and she adjusts techniques over time so therapy remains a good fit.

Online therapy makes this collaboration more accessible by offering video calls, phone sessions, live chat, and text-based messaging. These options allow scheduling flexibility, reduce travel time, and make it easier to maintain consistent care from a licensed professional while balancing the demands of daily life.
