Another option, that may or may not be usefui for your situation, is to set a Multi-Value list, then use the "Customize" menu option to choose to show the "Apply" button. This will make it so the user can search or check the list, and the filter will only apply once they've made all of their selections and chosen "Apply".

Thanks Matt, I had overlooked this option. The Apply button on the Multi-Value List is nice, especially if you take out the All option so not all of the names show up and slows down the rendering. My one concern right now though is not being able to clear all of the selections at once. Having to go through and search for all the names in the view is a bit tedious and I want this to be as user friendly as possible. Dashboard will be on a public website for policy makers and general public with no Tableau know-how.
