Two Eyed Seeing Engineering Services is a 100% Indigenous owned firm based in Edmonton, Alberta, Canada within the Traditional Territory of Treaty 6 First Nations and the Métis Nation of Alberta.

As a project manager, corporate lead of HSE, and VP of business development working for Athabasca Minerals Inc. in western Canada for nearly 15 years, he successful led several exploration programs and turned industrial mineral prospects into profitable mining developments while collaborating with local Indigenous leaders and businesses to develop respectful partnerships. He worn several hats and fulfilled many roles for the company in project management, business development, HSE, environmental regulatory compliance, geotechnical surveying, mine and reclamation planning, estimating, and community consultations.
