He also has sustainable design experience, U.S. Green Building Council LEED documentation experience, building energy simulation modeling capability, standards and building code knowledge and widespread computer expertise.

He is a member of CDM Smith’s guidance committee for employees working in the energy discipline. He fosters activity and leadership within the community, ensures that the group’s technical questions are always answered and guides his co-workers in having useful conversations. Through his church, Mammen volunteers throughout the year at various service events, which include serving meals at Solomon’s Porch, packing meals for Feed my Starving Children organization, making breakfast or spending time with the children at Ronald McDonald House, volunteering at a local soup kitchen and caroling at an assisted living senior facility. Additionally, he functioned as the treasurer of his church this past year. During free time, he enjoys working out. He also plays basketball casually and in church tournaments. He participates in races (5K through 15K) whenever there’s an opportunity. In addition, he and his wife love traveling throughout the U.S. and abroad.
