The young people supported by GLYNI meet for weekly workshop nights, covering topics they are interested in finding out more about.
Mark said young people from all areas, backgrounds and social class approach GLYNI for help.
Mark has worked for GLYNI for over a year and says his job is very rewarding.
Many of the young people who attend GLYNI have been unable to "come out" due to prejudice in society.
For those young people who haven't been able to share who they are with friends and family, GLYNI is a safe environment where they can be true to themselves.
"They can't be themselves, so GLYNI gives them the chance to express themselves and talk.
Mark told how the Pride of Northern Ireland Awards were an excellent idea and the young people from GLYNI are excited that they have been invited to Stormont on December 3.
"The fact that the Daily Mirror and the Pride of Northern Ireland Awards has recognised GLYNI as a group and that young LGBT people are there has been a real positive boost for them.
