Ronnie Lee Roman, 44, was found guilty on seven counts of lewd acts on a child with the special allegations of multiple victims. The office said the jury deliberated for more than a day before convicting him.
Roman worked as a coach for an after-school program in the city and at Cahuenga and Vine elementary schools. As far back as 2002, he is said to have sexually assaulted children ranging from ages 8 to 11.
Six of the sexual assaults happened on schools grounds, according to the D.A.'s office, and one occurred at a victim's home.
Roman is scheduled to be sentenced on July 19. He faces up to 105 years to life in state prison.
