UMFS Charterhouse School

A shittiest alternative school in Richmond, that not only exploits traumatized children, but also exploits the teachers and therapist that work there. Well known for putting sexual predators and pedophiles in the same class room as sexually abused children.

I just raped my 2 year old sister. Now I get to go to UMFS Charterhouse school, where they will tell me I am a good boy, and I get to molest other kids in middle school.
