A.I.A., New Orleans Office Manager

“When I went over to the “dark side,” as an Architect working for an engineering company, I didn’t know how it would work out.  I’m happy to say that after 20 years, I enjoy assisting MCA’s engineering staff in coordinating with our clients and bringing projects to a successful completion.  I believe that it has made me a better Architect.”
