KEEN is a national, nonprofit volunteer-led organization that provides one-to-one recreational opportunities for children and young adults with developmental and physical disabilities at no cost to their families and caregivers. I will warn you that on their website they clearly state that there is awaiting list but don't be put off by that. For the sports program the waiting list is not that long although the swim program does have a waiting list of over 2 years, also the programs coincide with the school year The age range is very broad with the idea that once your child is in the KEEN program that they will grow up in it. They have programs for children of 5 years old to 21 years old.
KEEN's mission is to foster the self-esteem, confidence, skills and talents of its athletes through non-competitive activities, allowing young people facing even the most significant challenges to meet their individual goals.
If you know someone in the greater Washington DC area that would benefit from this program please pass this information along. If you would like to support this non profit there are many ways in which you can do that from donating directly to volunteering your time.
