Well I could meet one of my Senators very easily and do nearly every year. She and my wife have something in common, having both lost loved ones to opiate pain addiction and so we attend the same charity event each year. $100 donation and wait for the event window and you easily can get 20 minutes of one-on-one time with a Senator. She also tends to bring the mayor of my city with as a guest because they're longtime friends, so I can get a 2-for-1.
That said, if I tried calling her office I'd never get past the intern.
