About ExpoLog

Leadership Team


Ken Yablonsky: Founder and Editorial Director

As Editorial Director, Ken oversees all operations and the editorial team, as well as client services. He carefully analyzes the unique needs of every client project to assemble the best team of writers and editors – taking into consideration the unique skill set and mathematic strengths of each member of the team – which in turn ensures the final product is of the highest quality. Ken also has a deep understanding of both the content and production sides of curriculum development. Clients trust him to help identify and solve issues or predict the impact editorial or marketing decisions may have on the logistics of developing an entire program.

Prior to founding ExpoLog (formerly Yablonsky Communications) in 2011, Ken was Editorial Director for 10 years at MathQueue, Inc., a mid-sized editorial services firm where he oversaw all staff and client deliverables and managed the firm’s bandwidth. He holds a bachelor’s degree in Mathematics Education and taught mathematics at the high school level for 10 years before moving into curriculum development. He also has a passion for developing and mentoring youth outside the classroom as demonstrated by what he spends time on in his free time: He’s coached sports at all grade levels – from first grade through high school Varsity – and holds various leadership positions within youth sports organizations including serving on the board of the state of Ohio’s Amateur Athletic Union (AAU) program. He also is chair, board of directors, for a Teen Center that offers after-school and community service programs. His personal mission is to help young people to excel in education and to build young adults’ character and leadership skills via the valuable life lessons offered through sports and after-school programming.
