Introducing Keith Engineering Design

Founded in 2005 as an electrical engineering consultant, Keith Engineering Design grew quickly into a full-service mechanical, electrical, plumbing and fire protection (MEP/FP) engineering consulting firms serving healthcare, educational, industrial, commercial and municipal clients. We specialize in the design of systems for new facilities, renovations to existing spaces and expansions to meet the needs of growing businesses.


Our overriding commitment to quality begins with the involvement of our key principals in every project. Our leaders play active, direct roles in project management, engineering, estimating and quality control, and we bring years of experience working for electrical and mechanical contractors to the table. That perspective gives us insights into installation issues, project costs and construction schedules that help ensure your project runs on time and on budget.
