What Our Clients Say About Us

"I’ve been a support coordinator for years, and finding the right therapy providers for my clients can be a challenge. Many providers have long waitlists, poor communication, or just don’t put in the effort to tailor their support. But Sigma Therapies has been a game-changer for the participants I support. They’re responsive, flexible, and genuinely care about outcomes. One of my clients, who has complex behavioural challenges, was struggling to find a provider willing to work with him. Sigma not only took him on but went above and beyond to develop strategies that actually worked. The progress has been incredible, and the family is finally feeling some relief. I wish more providers operated like Sigma – professional and dedicated to real change."

What Our Clients Say About Us

"Before finding Sigma Therapies, we felt completely lost. Our 7-year-old son has autism and severe anxiety, and we were constantly walking on eggshells to avoid meltdowns. Other providers kept giving us generic advice that just didn’t work for him. But from our very first session with Sigma’s PBS team, I knew we were in the right place. They actually took the time to understand our family and what he needed. They taught us practical strategies that made an immediate difference – things as simple as adjusting how we give instructions or changing his morning routine have made our days so much smoother. Most importantly, they reassured us that we’re not bad parents and that things can get better. And they have. I honestly don’t know where we’d be without them."

What Our Clients Say About Us

"When my daughter was diagnosed with developmental delays, I felt completely overwhelmed. She was struggling with basic things like holding a pencil, using scissors, and even dressing herself. I didn’t know where to start. A friend recommended Sigma Therapies, and I’m so glad they did. Her OT sessions have been amazing – it’s all play-based, so she has fun while learning the skills she needs. In just a few months, we’ve seen huge improvements. She’s more confident, more independent, and even her teachers have noticed the difference. The team at Sigma is so patient and kind – they celebrate every little win with us, and it really feels like they’re in our corner. If you’re looking for an OT who actually cares, this is the place."

What Our Clients Say About Us

"When my husband had a stroke, our whole world turned upside down. We had no idea what to do, and trying to navigate the NDIS while also caring for him was exhausting. A friend told us about Sigma Therapies, and honestly, they’ve been a lifeline. His OT helped him regain strength and mobility, while his psychologist helped him (and me) process everything emotionally. It’s been a tough road, but having a team that actually understands and doesn’t make us feel like we’re just another client has made all the difference. They check in on us, adjust his therapy plan as needed, and actually listen to our concerns."
