Take a look at what some of our clients have to say!

Trekk Advisory came highly recommended by a colleague and I am so pleased that I made the move. I am a small business owner and tax and numbers completely overwhelm me. I finally feel I have the support, very thorough feedback, all questions answered and the team are extremely generous with their time.I can’t speak highly enough of this firm and will strongly recommend to family and friends.

The team at Trekk came highly recommended to us several years ago, and we can’t imagine growing our business without them. They are brilliant at what they do, care about their clients, and, with their help, we have become better business owners with a healthy work-life balance.

I have dealt with Gavin and his team for more than 10 years now, as both Overells and Trekk. They are well organized, professional, technically very capable and respond promptly to all requests made for assistance. I highly recommend Trekk as an accounting / advisory service to both businesses and individuals.

Tony and his team have been our business advisors and accountants for the past ten years and, in this time, have provided excellent advice and service that has enables us to grow our business consistently. We were also facing strong headwinds due to the pandemic, and again the advice and assistance offered was the first-rate.
