Teresa Zumwald

CEO, Speechwriter & Storyteller

Opening her own shop in 1989 was an experiment that’s never ended for Teresa Zumwald, a speechwriter, speech coach, communications consultant and three-time corporate history book author.

At Zumwald & Company, LLC, she works one-on-one with brilliant CEOs, entrepreneurs and subject matter experts to tell stories that resonate.

In 2009 she added speechwriting to her repertoire, and since 2013, her speeches have won 15 international, national and regional awards including nine Cicero Speechwriting Awards from Vital Speeches of the Day. Among her speechwriting clients are board chairs, CEOs, presidents, vice presidents and a former chairman of the board of two global manufacturing companies based in Europe.

Teresa also manages complex communication projects, working closely with executives, managers and administrative staff as well as graphic designers, web developers, videographers, photographers, printers and other supplier partners. Her award-winning copywriting work – recognized by eight professional organizations – has been published in 50 magazines, journals and corporate publications and online.


Before creating Zumwald & Company, Teresa was a communications specialist for Geographic Information Services at Woolpert, a national architecture, engineering and geospatial firm. She has been a reporter/copy editor for the department of University Communications at The Ohio State University, and a writer/copy editor for Diagnostic Medicine magazine in New Jersey.
