Stephanie Hubka, CPTD

Managing Partner

Stephanie Hubka wants to live in a world where learning is exciting and inspiring and training is recognized as a natural driver of an organization’s strategy- and Protos Learning was born to do just that.

Stephanie moved to Washington, DC days after graduating with a degree in political science from Carnegie Mellon University with a goal of securing a job on Capitol Hill and eventually becoming president of the United States. No one was more surprised than she was to accept her first job as a coordinator in the education department of a nonprofit. It took just a few weeks for her to forget about her political aspirations and realize she had found her passion!

Throughout her career, Stephanie has enjoyed opportunities to develop training events and eLearning courses for learners around the world. She has served as a featured speaker on topics including storytelling, instructional systems design, training evaluation, and social learning. She was proud to earn her Certified Professional in Talent Development (CPTD) designation in 2011 and is an active volunteer and advocate for the certification. She has served as a board member of the Metro DC Chapter of the Association for Talent Development (ATD) and led the chapter as president in 2016 (she grew up to be president after all!). She currently serves as the co-lead for the Metro DC ATD Free Agent community of practice. She also served two terms as an ATD National Advisor for Chapters.

Stephanie’s love of training is equaled only by her love of exploring the globe; an avid traveler, she has visited all 7 continents, 70 countries, and all 50 U.S. states. Stephanie and her husband Adam write about their adventures at, where they work to inspire working professionals to put their paid time off to good use.
