As a chapter volunteer, be prepared to explain why you are involved, what the chapter does, and why others should join the team. With other board members, practice your "elevator pitch" to be fully prepared to recruit new board members.
An enthusiastic board with a "deep bench" is the most important attribute of highly functional, sustainable BHAN chapters.
Surveys can be an effective way to announce the launch of a chapter, learn what interests other alumni, and recruit new board members. The Alumni Relations office has an account with Surveymonkey which you can use for your chapter's survey. Contact email@example.com for account access, best practices, sample surveys, and to get started.
