I have been working with children and adolescents and their families for over 33 years. Therapy includes sessions with child and consultations with their parents. When appropriate and with the parents’ permission, consultations with teachers and other school personnel are conducted. I will speak with any person that impacts your child’s life. Ultimately, the goal of therapy is to create conditions in your child’s life that will lead to their growth and development.


I have a great deal of experience and success with children with special needs and various forms of over-sensitivities: Autism, Asperger’s Syndrome, Hypersensitivity, unusual forms of anxiety. I have taught children with Asperger’s Syndrome how to socialize and interact with others in ways that promote mutual respect and cultivate friendships.


I am a Certified Clinical Trauma Professional with a deep understanding of trauma, post traumatic stress and accumulated stress injury. I conduct evaluations, provide psycho-education and treatment. Help is provided to clients of all ages. I also do presentations on Trauma, Post Traumatic Stress & Accumulated Stress Injury for groups and organizations free of charge.
