Join us this year for #GivingTuesday!

GivingTuesday is a global day of generosity that will take place on November 29, 2022. Created in 2012, it started as a simple idea: a day that encourages people to do good. Over the past ten years, this idea has grown into a global movement that inspires hundreds of millions of people to give, collaborate, and celebrate generosity. We hope that this year you will join us in achieving our mission. Together we can continue to maximize the quality of life for those with developmental disabilities in our community.

“Put simply – he could not have been living in a better circumstance anywhere, and I have deeply appreciated that “the ship has somehow managed to sail on, thru the storm. I cannot imagine it being any harder…and I cannot imagine a job more well done. Please accept my deepest gratitude to all for getting Andy through this last year and a half, and for sustaining what I have come to believe has to be the best supported living agency in America.”

Nick, parent

Alpha is a very comfortable agency to live with. I’ve lived in Alpha for over 8 years. I’ve met a lot of new friends in the past 8 years.
