“Helping as many families and their children as we possibly can”

Gerd Winkler

Director of global Autism solutions

Prior to creating Global Autism Solutions in the summer of 2018, I worked as a Son-Rise-Program® teacher for the Autism Treatment Center of America® for the past 28 years, working with families and professionals in the United States, Great Britain, Ireland, Norway, Sweden, Denmark, the Netherlands, Belgium, Germany, Poland, Portugal, Greece, Italy, Croatia, Slovenia, Bosnia-Herzegovina, Serbia, Bulgaria, Mexico, Canada, Singapore, Indonesia and Japan.

I have had the great privilege of working directly with over 4000 families and their amazing children with autism through in-home services, through educating parents and their staff in their home-based programs, helping to integrate children into school and public life, and by providing ongoing support through video/phone consultations.

My new support services are designed to help families and caregivers enable their children to dramatically improve in all areas of child development, all through an approach of acceptance, appreciation, respect and enjoyment of the child.

Having had the privilege to work with children and adults on the Autism Spectrum has been by far the biggest blessing in my life and helping as many families and their children as I possibly can continues to be a passionate calling and the central mission of my life.

Joana Prata

Global Autism Solutions Teacher

I am the mother of a 14 year old boy on the autism spectrum and have been running a successful home-based program for the past 11 years, following the Global Autism Solutions Approach under Gerd Winker. My son is now a happy, social boy who loves to make friends and enjoys activities with peers. I have pursued further training with Gerd Winker and I am currently working with families in Europe.

I have a professional background as a Clinical Psychiatrist and researcher with a Postgraduate Certificate in Special Education Autism (Children) by the University of Birmingham. Since 2015 I have focused my research on the autism spectrum and have published several papers in international scientific journals.

I believe that parents are the child’s best resource and that love, attitude and using the child’s motivations are key to invite connection and growth. Over the years, having support from other parents on the same journey has proved to be a remarkable resource.

Wakako Wheelock

Global Autism Solutions apprentice / staff

I was born and raised in Japan, and have lived in the U.S. since 1998. I am a language and culture geek. I’ve lived in France, Yemen, and Kuwait to learn the language and culture there, and I consider Autism as a culture with its own language (communication) as well.

I have worked with over 400 preschoolers, about half of them needing special support. I have experienced over and over again how children show up as their best self when we provide an environment where they feel safe, loved, and accepted. Global Autism Solutions Approach is by far the best approach I know to provide the best environment for children to unlock their true potential and thrive.

I am so honored to have Gerd as my mentor to carry on his experience, wisdom, love and passion to support children and families all over the world.

I bring in my knowledge of Neurological Reorganization to further facilitate the journey when working with families.

“After many wonderful years of working together, we offer our support to Gerd as he follows his choice to take a different path and no longer provide Son-Rise Program® services.  Whatever direction he chooses to move in, we know that he will continue to be a caring and supportive resource for children and families.”

From Gerd Winkler

It has been my great pleasure to work with the Autism Treatment Center of America® these many years.  Although I am taking a different path at this juncture and am no longer providing Son-Rise Program® services, I wish the organization every success moving forward.  I know that both the ATCA and I will continue to offer loving support to families and their children in different ways.

I will stay active in the field of Autism and Special Needs Education by providing my own professional services.
