“We moved into our new home almost a year ago and knew we had a unique septic system and didn’t know much about it. Marshall was very helpful in communicating with us and helping us to better understand our system. He is always great about checking in and making sure we aren’t having any problems. We are so glad he is as responsive as he is and takes care of us! Going into this new home and system not knowing what to expect, he and his company have sure made it all easy to understand and manage!”

“I have known Marshall for over 17 years, even before he was an engineer! I know him to be a hard working, honest, reliable and a knowledgeable professional. Even as a fellow engineer, I often call upon Marshall for his decentralized wastewater treatment design, construction, and O&M knowledge, expertise, and insight.”

“I have worked professionally with Marshall for 30+ years in the decentralized wastewater industry. I have been his manager, his colleague, his client, and his contractor. Marshall’s attitude and integrity have never changed. He is honest, fair, and always expects results. He continues to be a professional and personal asset.”
