Some of the most useful contacts you have are in your alumni network. Attending the same university or graduate program gives you a shared history — and a great excuse to connect with other interesting, accomplished people. But how do you stay in touch with your peers? One easy way is to provide an annual update to your alumni magazine. Reading about what you’re up to can encourage old friends and colleagues to reach out. You could also volunteer for a role that will connect you with classmates. For example, you might serve as chair of the class reunion or launch a monthly alumni breakfast in your city. Or consider how staying connected could let you showcase your expertise. Alumni offices frequently host professional development webinars; you could volunteer to host one, sharing your knowledge with hundreds or even thousands of fellow graduates. Strategies like these will help you deepen your ties to fellow alums, and can even lead to valuable new business opportunities.
