I worked at Paralyzed Veterans of America (More than 3 years)
Wonderful place to work. The people made PVA a top rate place to have a career. The mission of PVA is superb and I would work there again without a doubt.
The only con I can think of is lack of identification of tomorrow's leaders today.
Advice to Management
I would recommend that there be a formal employee step up program so that the continuity of their business and mission would be seamless with any transition of staff.
