Upon his graduation from college, Sheneman was hired by "The Star Ledger", becoming the youngest full-time editorial cartoonist in the United States at the age of 23. His cartoons, which are syndicated nationally by TMS, have also appeared in "The New York Times", the "Los Angeles Times", and "The Washington Post", among others. Sheneman joined many other cartoonists at the 2004 Republican National Convention and 2004 Democratic National Convention, traveling to New York City and Boston, respectively, to cover the proceedings. He has not visited any such conventions since then.
