Operating Philosophy


"We believe that the best partnerships are not based solely on a common goal or an exchange of services, but rather are rooted in a shared set of values, understanding of our client's vision, and a passion to help them realize that vision"



Our commitment to this Mission and Philosophy and the importance we place on collaboration is a key differentiator for our company.  We see ourselves as members of our clients’ teams with an overarching vision to be the first call our clients make regardless of a project's alignment with our core services.  To this end, we seek out strategic partnerships with professional engineering and environmental services firms across the country to ensure we always provide our clients the most comprehensive expertise and best added-value possible.  This strategy also allows MME to remain highly adaptive to our clients changing needs throughout the entire life cycle of a project. 

Additionally, our team’s experience working as part of multi-disciplinary teams and delivering projects with conventional and alternative project delivery models, such as Design-Build, CMGC, and P3’s, provides MME with the unique skill set and value proposition not offered by many small firms.
