Is your child or teen having emotional issues, trouble socializing, behavioral concerns, or issues with bullying? Working with children/teens through their struggles and providing clear strategies to help is a passion of mine. Do you suspect that you or your child may be on the Autism Spectrum, have a learning disorder, or perhaps have complex mental health issues that have been misdiagnosed? We can provide accurate, impactful, and life changing evaluations to give you and your family the answers you need and a clear direction forward.
I provide gold-standard testing and evaluations for Autism throughout the lifetime (children to adults). My therapy approach is never predetermined before we meet. Whether it is cognitive-behavior therapy, relationship/family approach, or more dynamic or insight oriented; we work together to find the approach that best fits you and your concerns or needs.
I believe that no problem is beyond hope and that change is always possible, though not without some hard-work, perseverance, and adapting our approaches and attitudes. If you or a family member is interested in beginning therapy, please contact me for a free 10-15 minute phone consultation.
