"Children who have witnessed family violence will need support in a variety of ways, as will their parents or caregivers. We aren't here to insist people make a particular choice, but rather to help them find their own way and to not only make their own choices but to be happy with them as well."
Whether it is working with young people who are before the courts, working with people who have experienced domestic violence from their partner, working with people who have been charged with a domestic violence offence or working with children on ways to deal with bullying at school, Sinead says there is no one part of her job that is the most rewarding.
"Rather it is a case of every day knowing you have been involved in something which is quite literally changing lives. You are helping people in a really practical way and equipping them with skills they will use in the future as well."
While she has a desk and office at the Tutaki Youth Inc premises on Juliet Street in Stratford, Sinead's job means she is often out and about in the community.
"At the start of the day I check my emails to see if the police have logged any family violence callouts overnight, or over the weekend. If they have the first thing I will do is visit those addresses to have a chat and leave my card."
Sometimes, she says, people don't want to talk or see her turn up.
"But that is okay, it is about consistently being there. Welcome or not, they know we will show up, we will be ready to listen, to help and to support and while they may not want that now, one day they might, so it is important they know they can rely on the fact we will be there."
People can presume she is there to tell them to leave a violent partner, says Sinead.
"And that absolutely isn't the case. It isn't my job to say what someone must do, but it is my job to make sure they know what their options are, as well as knowing what help is available, including help for people to learn how to control anger and how to resolve conflict in a non-violent way. The only result I want to see is one where everyone in that situation feels happy and able to move forward, violence free."
After completing her visits for the day, Sinead can be involved in a wide range of activities and programmes, both at Tutaki Youth Inc and out in the community.
"No two days are the same, but they are all equally rewarding."
