Renoir Valenti, 54, was also ordered to pay $450,000 in victim restitution and register as a sex offender for life.
In February, he was found guilty of 20 counts involving 15 victims ages eight to 12 years old. He faced a maximum sentence of 154 years to life.
Valenti was a coach in Lancaster with the American Youth Soccer Organization.
The alleged crimes happened over the span of at least a decade, and detectives say he used his position to befriend young boys. The suspect molested a girl and 14 boys, including six soccer players he coached.
