Avi Benjamin Grant became a bar mitzvah Nov. 9 at Congregation Har Shalom in Potomac. Joining in the celebration were his parents, Susan and Darryl Grant of Potomac, brother Jacob, and grandparents Murray and Trudy Grant of Silver Spring and Marilyn Feldman of New York, N.Y. For his mitzvah project, Avi participated in a three-mile walk in support March of Dimes/March for Babies. Since Avi was a micro-preemie himself, supporting March of Dimes was very important to him. Avi is a seventh-grader at Herbert Hoover Middle School in Potomac.
