Mark Grayson has been leading HMH’s Science product development team since November of 2018. His time in the industry began in January 1991, when he joined what was then Holt, Rinehart, and Winston as an entry-level chemistry editor, a sneaky way to apply both his B.S. in Biochemistry and his M.A. in Journalism. In 2008, Mark joined a development firm, Six Red Marbles. There, he planned and executed curriculum projects for clients including Apple, Discovery Education, HMH, McGraw-Hill, and Pearson. Mark re-joined HMH in 2015 as part of the recently formed Science Product Management and Strategy team, helping guide the development and launch of the HMH Science Dimensions^® program.

Mark is an unabashed junkie of the politics and history of both Texas in general and Austin in particular. He was appointed by his local Austin ISD school board trustee to the citizens’ committee that successfully crafted a 20-year master plan for the district’s facilities as well as a $1 billion facilities bond proposal that won in the 2017 election by a 72% to 28% margin. He continues to monitor that spending as a member of the Austin ISD Community Bond Oversight Committee.
