Legislative staff members are often overlooked when a constituent is seeking to "meet with Congress." Some people construe a visit from a lawmaker's staff instead of the actual lawmaker as a slight to their interests. This is an enormous misconception.
Staffers may be familiar with banking in general, especially from a customer perspective, but the unique mechanics of a community bank might not be intuitive. A "Community Bank 101" can go far in creating a basic understanding, for instance, of how a loan is processed from origination to disbursement, or an explanation of the scale and structure of the staff at your bank and how the already limited resources available due to the size and scale of the bank are further encumbered by increasingly burdensome regulations.
Congressional staffers are a vital part of every member's office. Meeting with a lawmaker's banking or financial services staffer presents an excellent opportunity to initiate or nurture a relationship that allows for delving much deeper on substance and issues than most lawmakers have the time to devote. Meetings with staffers can generally be much broader in scope, and longer in length than the usual meeting with a Representative or Senator. The opportunity to demonstrate the "big picture" of how your bank impacts the community is only limited by time and your own creativity.
