Turn uncertainty into opportunity with a TED speaker who inspires leaders to laugh, learn, and lead through the unexpected—so they can handle anything that comes their way.

Mary Lemmer helps leaders and teams handle anything—especially the curveballs—with tools rooted in improv comedy, behavioral science, and real-world business savvy. A TED speaker, former venture capitalist, and director at successful startups, Mary started her first business as a teenager and trained as an improv comedian at the legendary Second City.


She’s partnered with some of the world’s biggest brands and scrappiest startups to boost resilience, improve collaboration, and spark innovation—especially when things don’t go according to plan. With a unique blend of humor, heart, and hard-earned insight, Mary empowers audiences to improvise through uncertainty and lead with more confidence, creativity, and connection.


Her forthcoming book, How to Handle Anything, captures the same mix of story, science, and spontaneity that makes her keynotes unforgettable. Whether she’s guiding teams through high-stakes transitions or helping leaders embrace the unscripted, Mary delivers a dynamic, energizing experience—leaving audiences equipped (and excited!) to handle whatever comes their way.
