About Kelli Nielsen (She/Her)

Kelli Nielsen, LPCC, helps children, teens, and adults across California navigate life’s challenges with greater clarity, resilience, and emotional balance. At LifeStance Health, she provides individual therapy for individuals facing anxiety, depression, and trauma-related concerns. Kelli approaches therapy as a collaborative and supportive process, creating a safe space where clients feel heard while working toward meaningful, sustainable change. Her work focuses on helping people understand the connection between thoughts, emotions, and behaviors so they can develop practical tools to manage stress, strengthen coping skills, and improve overall mental wellness. Kelli is especially passionate about supporting individuals who are working through trauma and post-traumatic stress. She integrates trauma-informed care with evidence-based approaches, including Eye Movement Desensitization and Reprocessing (EMDR) and Cognitive Behavioral Therapy (CBT), to help clients process difficult experiences and reduce the lingering effects of trauma. Through this work, she helps clients move forward with renewed confidence, emotional stability, and a stronger sense of personal control. In addition to her trauma-focused work, Kelli has experience supporting individuals experiencing anxiety and depression. She also works with specialized populations such as first responders and military or veteran communities, recognizing the unique stressors these individuals often face. Her therapeutic approach is thoughtful, compassionate, and grounded in proven mental health treatment methods that support lasting improvement. Outside of her clinical work, Kelli enjoys spending time with her family, traveling, dancing, and baking.
