It goes without saying that participation in professional organizations can very well behoove the modern professional. There are many benefits that come with being a member of a professional organization. The most obvious benefit is networking, and networking can help young students and professionals get a foot into the field.
In the last few years of my undergraduate college years, I was lucky enough to be a part of 2 organizations. Since I pursued 2 degrees in Journalism and Photography, then I participated in both the local chapter of Society of Professional Journalists (SPJ); and also National Press Photographers Association (NPPA). I volunteered at the national conference for each professional org, and it was one of the best decisions I ever made.
