Mullen is a phenomenal school. Both my son and daughter attend here. They are very different individuals, but they both LOVE this high school. They have thrived academically and could not be more prepared for college.

Scandalous administration. They cheat their vendors, specifically the female controller who is beyond ruthless and cheating. Outright diabolical. Be careful anyone doing business with this entity, they rank right up there with Enron.
