The 2026 Williams Syndrome Association International Convention to be held in Buffalo July 7 to 11

About 1,800 people are expected to attend the WSA Convention, held at the Buffalo Convention Center

BUFFALO, N.Y. – The largest Williams syndrome event in the country will take place in Buffalo this week. 

About 1,800 people are expected to attend the 2026 Williams Syndrome Association International Convention at the Buffalo Convention Center and the Hyatt Regency Buffalo from July 7 to 11. 

The WSA will feature 60 sessions led by top experts sharing the latest research, medical updates, and educational strategies on Williams syndrome. It will also include specialized programming for kids, teens, and adults with WS. 

Williams syndrome is a rare genetic condition that is present at birth and can affect anyone. It affects about 1 in 7,500 to 10,000 people worldwide. An estimated 20,000 to 30,000 people in the United States have Williams syndrome.

While in Buffalo, attendees will have the option to visit local attractions including Niagara Falls, a Buffalo Bisons game, and the Taste of Buffalo (July 11 and 12), as well as events at Canalside. Visit Buffalo is also helping to coordinate dining and attraction experiences for attendees through the Queen City Perks program.

The WSA Convention is held every other year. Visit Buffalo booked the 2026 WSA Convention in 2023. 

The event is expected to bring $5.19 million in economic impact to Buffalo, said Visit Buffalo president and CEO Patrick Kaler. 

“We are excited to have the Williams Syndrome Association International Convention in Buffalo, and we look forward to making a wonderful experience in Buffalo for the attendees,” Kaler said.
