Spokeswoman Jane Robison says 44-year-old Jose Duarte was sentenced Tuesday after the parents of three of his victims addressed the court.
One parent told the judge that the molestation destroyed their family.
In February, a jury took less than a day to find Duarte guilty of 20 counts of child molestation and five counts of sending harmful material.
Duarte was arrested in 2011, one day after a 13-year-old boy on his team said he had been sexually assaulted.
The victims were between ages 11 and 14.
Prosecutors said the crimes happened primarily at Duarte's home, and he showed the children pornography before molesting them.
