National Stuttering Association Exec makes 110K per year (only full time staff)!!!!

National Stuttering Association Exec makes 110K per year (only full time staff)!!!! I just found out that Tammy Flores makes over 110K per year as the only full time staff member at the NSA. The NSA as an organization pulls in just under 500K per year. Here's the link for their financials (https://projects.propublica.org/nonprofits/organizations/942420533) and a link to the NSA (http://westutter.org/staff/). Please let me know your thoughts on this. Is she making too much? Too little?
