Our Team

Tom Nieman



Tom Nieman, a graduate in English from Northwestern University, started off as a grade school teacher. He began Nieman Inc. in 1998 after 18 years at ScottForesman, where he worked as an editor, editorial VP, product manager, marketing director, and supplemental publisher. Today, in addition to his role as president of Nieman Inc., he volunteers as a reading teacher and tutor for English language learners at St. Thomas of Canterbury in Chicago.

Mark Hansen

Vice President


Mark came up as a reporter, tennis coach, and enthused student of literature. He latched onto the mix of wordsmithing, collaborating, and charting that comes with ed pub work when he joined Nieman in the mid 2000s, starting on a long run of secondary literature and assessment work. Mark graduated from the University of Kansas with a double major in journalism and English.

Liz Semro

Business Manager


Liz began her publishing career at ScottForesman. She has worked on the business side of things since the beginning—in the SF elementary/high school math and reading departments and the supplemental division. She joined the Nieman team in 1998. Liz holds a degree in English from the University of Iowa.

Luz holds a liberal arts degree from Sarah Lawrence College. She volunteers her digital media and web development skills to local nonprofits and civic hackathons.

Erin Dye

Senior Editor and Project Manager

Erin joined Nieman in 2010. She has prototyped, managed, edited, or written a wide range of programs across the K–12 spectrum. She focuses on reading, but she also has a soft spot for social studies. Erin holds degrees in art history from Randolph-Macon Woman's College (B.A.) and the University of Chicago (M.A.), and she loves putting her liberal arts education to use every day at work.

Tom Klonoski

Jessica Rzepka

Senior Editor and Project Manager


After earning a B.A. in creative writing from Illinois Wesleyan University, an M.A. in English from Illinois State University, and most of a Ph.D. in Medieval and Renaissance Literature from Loyola University Chicago, Jessica finally realized that there was a better way to demonstrate her passion for education than by simply staying in school forever. She joined the Nieman team in 2012 and has since participated as a writer, editor, and project manager. She specializes in high school ELA and digital learning but always welcomes new challenges.

Nicole Roth

Senior Editor


Nicole joined Nieman in 2010 after earning a B.A. in English-Creative Writing from Northwestern University. As a writer and editor, she has worked on K–12 student editions, teacher’s editions, ELL kits, and assessment. Most of her experience is in elementary reading, but she also enjoys working on literature programs and trying new subjects.
