I have found LegiStorm essential for my job and quite surprising in its capabilities. For an arts presentation I needed to give on Capitol Hill, I was able to automatically download key arts staffers associated with all members of the Congressional Arts Caucus. I was also able to find staff with "art" in their education backgrounds, so they got invited too. Definitely fun, and useful.

We have found LegiStorm to be the ultimate tool in communicating with congressional offices, either individually or with a group. We have been able to reach out with messages to all chiefs of staff and legislative directors, or staff dedicated to specific areas. We believe that this ability was instrumental in passing two key pieces of legislation which were imperative to our members.
