I don’t say this lightly — but I give Gallant Law a five-star review.
We work closely alongside Lauren Cassimatis, and... read more I’ve seen firsthand how she shows up for people — especially those coming out of the system.
At About Time for Justice, we work with survivors of institutional child SA right across Australia.
But the clients we send to Lauren are predominantly based in Victoria.
We’ve referred multiple clients to her who are in and out of custody — people trying to get back on track and break the cycle.
A lot of our clients can’t self-fund.
They’ve got a criminal history.
They’re trying to rebuild.
Lauren understands that.
She works within legal aid.
She doesn’t turn people away.
And she treats people with respect — not judgment.
But what stands out most…
She doesn’t just sit behind a desk.
She shows up.
Community events.
Real conversations.
Real support.
That matters.
If you’re criminal justice affected and need the right kind of legal support — someone who actually gets it — I back Lauren.
I trust her with my clients.
And I don’t say that unless I mean it.
