Dylan Bennet Klebold was born in Lakewood, Colorado, to Thomas and Susan Klebold (née Yassenoff). His parents attended a Lutheran church with their children, and Dylan and his older brother, Byron, attended confirmation classes in accordance with Lutheran tradition. At home, the family also observed some rituals in keeping with Klebold's maternal grandfather's Jewish heritage. Klebold attended Normandy Elementary in Littleton, Colorado for the first two grades before transferring to Governor's Ranch Elementary and became part of the CHIPS ("Challenging High Intellectual Potential Students") program. He found the transition to Ken Caryl Middle School difficult.
