Our Practitioners Are The Heart of Trellis

"What motivates me is the opportunity to recognise and amplify the incredible work that families and support teams are already doing. By acknowledging their strengths and celebrating their efforts, we lay a strong foundation of confidence; one that empowers them to embrace and implement meaningful, positive change."

"I love supporting people to build meaningful lives where they feel heard, valued, and in control. Seeing someone grow in confidence and independence is what motivates me every day"

"Working at Trellis aligns perfectly with my values — keeping my participants at the centre, showing kindness and respect, and being part of such a supportive team. It makes me genuinely happy to come to work every day."

"I’m passionate about empowering people to live lives that feel meaningful and self-directed. Watching someone find their voice and build confidence inspires me every day. Trellis reflects my values of compassion, respect, curiosity and teamwork. I consider myself extremely lucky to be part of the Trellis Team."

"I love being part of someone's journey as they learn to advocate for themselves, make their own choices, and build confidence in who they are"

“It excites me to work with someone and help them discover new tools for navigating their own path, and forge connections that expand their community and offer new possibilities."

Article – Navigating Co-production in Behaviour Support: Perspectives from the Field

This paper – written by Nick Hagiliassis, Mark Di Marco, Susan Fowler, Stella Koritsas, Marcus Plush - looks at what meaningful co production in Positive Behaviour Support really requires. Practitioner reflections and lived experience insights point to a clear message: co production works best when plans are accessible, communication is flexible, relationships are strong, and each person’s preferences and rights guide the process.
