July is Disability Pride Month

On July 1, the Lake Oswego City Council will officially proclaim July as Disability Pride Month. Disability Pride Month is an annual event celebrated in July to commemorate the passing of the Americans with Disabilities Act on July 26, 1990. It recognizes and honors the history, achievements, experiences, and struggles of people with disabilities.

Disability Pride Month promotes visibility and mainstream awareness of the positive pride felt by people with disabilities, celebrating diversity and fostering a society that is inclusive and accessible to all individuals, regardless of ability.

We invite you to celebrate Disability Pride Month with us - we have several activities and events planned throughout the month! All events are free and open to the public.
