Leonard Engineering began in 1987 as a sole proprietorship and was began as a close-knit family business. Having worked over 10 years within the industry with bigger companies, we were able to start to evolve business by going into the community, identifying customers with project requirements, and drawing from that depth of knowledge to suit those requirements.
