S.i.

Systems. “We share common values, common culture. I have known Stacey for 20 years and have always been impressed by his leadership and our strikingly similar values. This acquisition is a very good fit for both parties in so many ways. We warmly welcome all Annex staff and consultants into S.i. Systems.

Founded in 1998, Annex is one of the original IT staffing organizations in Vancouver.  They are well trained, knowledgeable providers of on demand IT professionals and outsourced IT services.

Their culture, processes, values and high-caliber talent are very similar to Annex.  We already run on the same principles, so the integration of the two firms will be swift and easy, and the combined organization will be a force in Western Canada,” said Stacey Cerniuk, CEO of Annex. “Vancouver is an incredibly diverse and meaningful economic community with a high demand for specialized IT professionals. Together we are now the largest IT staffing firm in B.C. with more talent for our clients and more jobs for our consultants.”
