Who We Are

Passionate Tree People

Since our inception in 2007 it has remained our primary objective in business to provide Lethbridge and area with excellent arboricultural service that exceeds expectations. We commit to not only adhering to the industry standards set out by organizations like the ISA*, TCIA*, ANSI*, OH&S*, and CTLA*, but to also evolve and elevate our expertise. From taking time out of production for formal training sessions, to attending industry leading courses and seminars, we put forth massive efforts to provide our community with an ever increasing level of modern urban forestry practice. Our impressive safety record along with our Better Business Bureau A+ rating speak for themselves, and there is always something new happening behind the scenes. We invest in modern practices and equipment to help reduce our impact, make less noise, and reduce our risk.
