Shmidman, son and grandson of rabbis, grew up in Montreal, Canada. He earned his bachelor's in political science and master's in medieval Jewish history from Yeshiva University.
When he arrived at Knesseth Israel in 1998, he soon began to push the congregation toward thinking about upgrading its facilities. Eventually the project resulted in a new $6.5 million synagogue on Overton Road. Shortly before its completion, Shmidman left to become the rabbi of the Lower Merion Synagogue in Bala Cynwyd, Pennsylvania.
