Of late I have been hearing about (IRSF) on National Public Radio's PSA's. I have an interest in not for profits and the work they do, so, I thought I would do a little investigating, and suffice it to say, it's a charity that now has my attention. Although a rare disorder, (IRSF) seems to be doing a GREAT job of spreading the word, and making known what the victims of this horrible disease face, daily. They sponsor "Strollathon's both locally in Cincinnati and nationally, and based on what I have read, they appear to be the absolute leader in research. Hopefully, I can make an impact, and along with your organization, inspire them to open their hearts, and then, open their wallets! Good luck and God Speed IRSF!!

Trying to find out any information about this foundation is practically impossible from the IRSF website - it's unbelievable that their Annual Report and 990 have not been updated since 2010!

Will you volunteer or donate to this organization?

Dear rgoodman, thank you for alerting us to this oversight. Our 2011 forms are now posted to the website. We are a small handful of people working intensively to accelerate research and support families. We operate transparently and with integrity, and with the support of scores of volunteers, mostly family members of a child with Rett syndrome, who are proud to represent our organization, and believe in our mission. Every phone call or email is answered promptly. We invite you to contact us directly with any question you may have, at any time. Sincerely, Paige Nues, Director, Family Support, IRSF
