Thornhill Lopez Center on 4th

The Thornhill Lopez Center on 4th (TLC4) is a SAAF place for LGBTQ+ and allied youth ages 13-24 to visit in order to access a variety of services to support their health and well-being.  According to the Human Rights Campaign (HRC), less than 50% of LGBTQ+ youth say they have an adult in their family they could turn to for help.  The top three most important problems for LGBTQ+ youth in their lives right now include non-accepting families, bullying and problems at school, and fear of being out.  TLC4 provides critical services and support for youth that need support.

TLC4 provides a SAAF place where LGBTQ+ and allied youth can go for:

  • Safe, drop-in services
  • Homeless youth support
  • Food, clothing, and housing-referral assistance
  • Showers
  • Suicide prevention programming
  • Sexual-violence prevention programming
  • HIV testing and counseling
  • Substance abuse prevention
  • Sex-positive education
  • Life skills
  • Referral to other community programs
  • Culturally competent care
  • Computer lab
  • Art expression
  • Peer socialization
  • A place to be themselves

“[When the center opened,] it made me feel validated. I knew that a lot of people, other than myself and my friends, would be able to appreciate the Center.“


– Yuvennice

“It’s a space where I can feel like myself in a lot of ways, and it’s a really great support system.”


– Axyl
