I was an active volunteer and board member in my local chapter. Then the celebrity national board decided to force our local chapters to send half of the money we worked hard to raise locally to their national office. That office pays over $ 1 million executive compensation and also rents highest priced office space available in Cicago. This caused many locals to layoff direct service staff. At least three former chapters have had to leave the National organization in order to provide high quality local services. And they have been treated with revenge by the National. But they are continuing to provide excellent services and even contribute to research without the overhead reduction the National applies.
