After all, having a father that spent the better part of 30 years servicing and maintaining some of the largest buildings in our city, laid the foundation for Emmanuel wanting to build a unique organization that provided the absolute best service, value and expertise.

Emmanuel’s extensive knowledge and experience have spanned many decades and several industries. His executive leadership roles with Fortune 100 organizations have enabled him to incorporate True Best Practices and bring a level of sophistication to an often called, unsophisticated industry, garnering praise from both clients and employees alike. Whether presenting to hundreds of property manager’s or consulting to hundreds of Board Directors, Emmanuel’s philosophy is to educate key stakeholders so that they have the right information at their disposal in order to properly define and meet their objectives. Emmanuel continues to serve on multiple boards, including his appointment as Vice President at CAI Canada.
