About Us

ExpoLog is a leader in mathematics curriculum development. What differentiates ExpoLog is our sole focus on mathematics editorial services. Our team of writers and editors specialize in math and understand the unique needs of math teachers and students.

ExpoLog manages math editorial assignments of any size. Our large and diverse team of 25+ core staff members and contractors can execute large bandwidth projects and high page counts - from standardized assessment revisions to full programs and everything in between.

We provide clients added value in the areas of strategy and project management. Our depth of mathematics experience (we’ve worked with nearly every major publisher in the industry!) means we have a deep understanding of publishing workflows – both content and production – and therefore can help clients identify and solve issues or predict the impact decisions may have on the bigger picture of an entire program.

We do digital. Let us put our experience with today’s online learning technology to work for you. We can develop content directly into your proprietary content management system or help move content to an on-screen setting complete with pop-up scripts, narration and other teaching aids.

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 for the past 15 years. 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.
