“If you are struggling with depression or anxiety, you’re going to have a much harder time concentrating in school and being able to complete your work.”
“We tell our kids we love them. They’re important to us.”
“When students understand they’re not responsible for the family they were born into, but they are responsible for who they will become as adults, and when they can see the power in that, it’s just amazing what happens.”
"We accept them for who they are. Their future is more important than their past.”

Gordon says it’s also the unconditional love that the teachers at Lincoln High show the kids on a regular basis."
