Are you worried about your child’s anxiety, low self-esteem, or mood challenges? Maybe your teen is struggling with academic stress, body-image concerns, or navigating friendships and relationships. Families may feel overwhelmed by conflicts, divorce, or life transitions. You want your child to feel understood, develop healthy coping skills, and gain confidence to thrive. You’re looking for guidance, support, and practical strategies that help your child and your family grow stronger together.

I specialize in child and adolescent therapy, using evidence-based approaches like CBT, EFT, narrative therapy, and attachment-informed strategies. I focus on early intervention, helping children and teens build resilience, confidence, and healthy coping skills while supporting families through life’s challenges.

I understand how stressful it can be to watch your child struggle or to feel stuck as a parent. I create a safe, supportive space where children, teens, and families can explore challenges, develop skills, and grow together. I’m here to guide your family toward healing, resilience, and lasting wellness.
