History

Founded in 2001, MJDII is a multi-talented firm based in Dallas 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. As MJDII has evolved, we have become a respected and trusted firm known for our collaboration of experienced professionals working together to create thoughtful and functional design. MJDII’s client relationships are built on trust resulting from our honesty, transparency and commitment to their core values. In October 2021, Johnston LLC, acquired MJDII Architects, Inc., 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 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 brings increased value for our customers.
