LEA Consulting has its roots in two companies: ND Lea & Associates Ltd. and Lazarides, Lount and Partners. As shown in the timeline, the names of the companies have changed several times over the last 65+ years.

However, the entrepreneurial spirit shown by the founders of these two companies and the desire to remain a privately held company owned and managed by its employees are principles which we continue to live by.
