Olivia is a warm and down-to-earth therapist who brings authenticity, empathy, and real-world experience to her work. She has worked across home, school, and community settings, supporting children and teens with autism, behavioral challenges, anxiety, and emotional regulation. She also has experience working with adults navigating life transitions, mental health concerns, and complex family dynamics. Olivia’s approach is collaborative and adaptable—she believes therapy should feel like a safe space to be real, ask hard questions, and not have it all figured out. She meets clients with honesty and respect, offering steady support as they explore whatever they’re going through. With a strong foundation in behavior-focused and trauma-informed care, she tailors her work to each person’s needs, always with compassion and curiosity.
