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, executive communications adviser and three-time corporate history book author.

At Zumwald & Company, LLC, she works one-on-one with brilliant leaders to tell stories that resonate.

In 2009 she added speechwriting to her repertoire, and since 2012, her speeches have won 22 international, national and regional awards including 15 Cicero Speechwriting Awards from Vital Speeches of the Day. Among her clients are board chairs, C-suite leaders, entrepreneurs and subject matter experts from the Fortune 500 and other U.S. and international firms including the former owner 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. She recently collaborated as the writer of a business book, authored by an executive, that was published in 2020 for stakeholders of a private corporation. Her award-winning copywriting work – recognized by eight professional organizations – has been published in 50 magazines, journals, 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.
