About Us

At Trellis we’re motivated by one simple promise: exceptional advice delivered with genuine care.

Our approach blends the technical depth you’d expect from a large firm with the accessibility and personal service of a boutique practice. Guided by our values—care, excellence, transparency and respect—we take the time to understand your goals and craft solutions that help your business thrive.

The result is business advice that is as precise as it is practical.

The Trellis story goes back decades. Founded in 1983 with a vision of providing complete and personal services to people in business, we evolved into Dewings and operated under this name for nearly twenty years at Hauteville Terrace in Eastwood. In 2025, with a transition of ownership, we became Trellis and moved into our current home on Greenhill Road in Wayville.

Directors Kathy and John have worked with us for over 30 years, having come on board as accountants not long after they finished high school. This continuity of commitment means we can honestly say that our purpose remains the same as it has always been – thoughtful personal service with exceptional technical expertise.
