Landon Alexander Warner became a bar mitzvah on Nov. 9 at Washington Hebrew Congregation. Landon is the son of Nessa and Greg Warner of Bethesda and grandson of Meryl and Jeff Cohen of Potomac. Also joining in the celebration were his sister Madison and friends from out of town. For his bar mitzvah project, he raised money for cancer, as both of his grandmothers had cancer. Landon is a seventh-grader at Pyle Middle School.
