“By supporting young creatives and fast-tracking the learning curve, the LIA Creative LIAisons program elevates the standard of our industry. It creates a self-perpetuating attitude among us to pass it forward, which is invaluable. What you can learn from one person’s experience beats anything you’ll find in a book.”
