Over the years, we have found ourselves working through industry challenges and serving our customers in a variety of ways from new construction to renovation, restoration and service work across Ontario. It is through these challenges we began our journey to expand our knowledge and expertise to what is now our new LESTER Project Solutions Suite: PLANNING / COLLABORATION / IMPLEMENTATION / CONTROL / CLOSURE

We don't want to be the biggest. We just want to be the best.
