Diversity is a Core Value of Social Work and is honored and pursued across every dimension but gender. Men are an ever-decreasing proportion of social work practitioners. Why is this happening? And why is it being allowed to happen with no sense of urgency, alarm or even concern from Social Work leadership?

If so, how does this hurt the profession and, more important, the clients we are duty-bound to serve? Finally, what can be done to solve this multi-dimensional problem?
