Sheryl Kaczmarek | Lexington Debate Coach
I am currently in my 35th year as a debate teacher and coach. I began my career at Brookfield Central HS in Wisconsin during the 1982-83 school year. In those days, I coached speech and policy debate, since the other types of debate had not yet reached Wisconsin (or been invented yet). After 10 years in Brookfield, I spent one year at Glenbrook North, teaching and coaching policy debate. I then went to Newburgh Free Academy, a public high school in the Hudson River Valley region of NY. I coached Policy, LD and PF in Newburgh for 21 years, before moving to Lexington three years ago. I now teach a full schedule of debate classes, including Policy, LD and PF. I am a Four Diamond Coach in the NSDA, a Key Coach at Emory and a member of debate coaching Halls of Fame in Wisconsin and New York. I am also a member of the TOC advisory board for Policy Debate, a member of the NDCA Executive Board and a member of the Tab Staff for Policy Debate at the NCFL National tournament.
