Founded in 2001, Johnston is a multi-talented firm based in Houston that provides project/program management, architectural design and MEP engineering design services that span all disciplines and project phases. Our unified team is comprised of architects, engineers, construction administration, and quality assurance professionals who seamlessly collaborate to develop thoughtful solutions.

In October 2021, Johnston acquired MJDII, integrating two client-centric firms who have similar values, diversity and culture, while keeping those values top of mind: Trust. Respect. Integrity.

Johnston and MJDII, with over 40 years of combined experience, have expertise in advancing technology, industrial, manufacturing, aviation and research facilities, as well as for healthcare, government and commercial clients. The ability to offer our clients architecture and MEP engineering services and the addition of exceptional talent to both teams bring increased value for our customers.
