Scott Kramer, Founder of GCA Centre for Adult Autism

Scott Kramer, the founder and program director for the GCA Centre for Adult Autism in Chattanooga, the Annual Southeast Adult Autism Symposium and a longtime advocate for autistic individuals, passed away on September 6th, 2019. He had been battling Stage 4 colon cancer.

Before he lost his cancer battle, he created the GCA Centre for Adult Autism—a program under the Chattanooga Autism Center. The program offers support groups and social events for autistic adults/adults on the autism spectrum.

Scott Kramer was a devoted advocate for autistic individuals and also a huge fan of Chattanooga Football Club.

The Club paid tribute to him at the last home match in this video. His team surrounded his family and fellow fans had a moment of silence followed by a minute of applause. (more)
