"PR is not a comfortable area for us at VB+P. We’d rather do the work than boast about it. But Katie and Leslie have helped us shape our narrative in a way that’s true to who we are, while being strategic and effective in getting our name out there. They are our honest and fearless partners."

- Paul Venables, Founder, Chairman



Katie Kempner, Founder

Kempner Communications was founded by Katie Kempner, an industry thought leader who has spent her entire 18-year career both with the renowned advertising agency CP+B and their holding company MDC Partners. Most recently Chief Communications Officer for CP+B, Katie oversaw global communications for the agency throughout their eight global offices. She initially originated the role of Communications Director at CP+B in 1996. Under her media guidance, CP+B and their work received tremendous industry and press recognition, which was instrumental in the growth of the agency. In January 2004, while continuing to run the CP+B communications department, she joined parent company MDC Partners as Sr. VP, Director of Corporate Communications where she helped establish their reputation in the US, oversaw all communications for the network and provided strategic communications counsel to their partner firms. In 2011, she returned solely to CP+B to focus on global growth.

Katie considers herself extremely fortunate that when she left to realize her dream of owning her own firm, CP+B came along as a client. A graduate of The University of Miami, Katie lives in Miami Beach with her husband, two children and two dogs.

While at CP+B, Leslie also filled the role of VP/Communications Director, which was her first stint working with Katie and where she was instrumental in the agency’s global communications work with a particular focus on the LA office’s evolution and growth. Leslie’s blended background in communications and account work has built her strong skills in brand strategy, process-driven collaboration with agency teams and a keen understanding of how communications efforts contribute to larger business goals.
