"There are many people who have practiced PR in the Advertising industry. There are not many people who have done it as successfully and artfully as Katie Kempner. Her approach is always fresh, always thoughtful and always thorough."

- Nancy Hill, CEO, The 4 A's



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.


Leslie Repetto, VP/Director of Client Services

Leslie Repetto is a VP/Director of Client Services with Kempner Communications, working closely with Katie to lead client partnerships and strategize and execute on their behalf. Leslie brings nearly two decades of experience in the advertising industry, much of that time spent as an account leader at agencies including CP+B, Arnold Worldwide and Modernista!, and with clients such as Volkswagen, Old Navy, Bolthouse Farms, Gap, MTV, Microsoft Bing and Converse.

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. Leslie lives in Los Angeles with her husband and their very silly and sweet, always running toddler.

"Katie brings insight, savvy, grace and fun to every situation and her judgment is a treasure. She's been a great PR mentor to me. When Katie is on your team, good things happen."  

- Matt Jarvis, Partner and CSO, 72andSunny

"Katie has been such a huge force for good for us over the years. She has helped us develop our own brand and frankly she basically taught other agencies how to become bigger brands themselves through smart PR. If you know her, you know she is tenacious in making something good happen she believes in. We are completely supportive of her having her own company and it’s great for us that we are still able to work with her as a client." 

 - Jeff Steinhour, Vice Chairman, Founding Partner, CP+B

"Katie is a real thought leader with innovative approaches and insights who is passionate about what she does. Through her extraordinary talents, skills and resources she has changed the face of one of our major fundraising luncheons by bringing amazing speakers to the table and then leading them in inspiring keynote conversations. She is also an incredible role model for all of our members juggling the demands of her high profile career and her family and still finding time to volunteer to help women in her community. I truly value Katie’s guidance and admire her professional and interpersonal skills."
