Marianne's dad was a union plumber for many years. Growing up, she was his apprentice, and she helped him with all aspects of their home renovation projects. Because of this, she has always loved construction and design. She eventually went on to become a lighting designer.
Prior to moving to the Cape Ann area, Marianne spent 25 years in a MEP
design engineering firm. While she wore many hats, she was primarily responsible for providing electrical drawings and specifications for high-efficiency lighting designs. She also managed these projects through the bid process, bid awards and final punch lists. She thoroughly enjoyed being a part of a team and the feeling of seeing what she had a hand in creating.
In her new role at Mill River, she once again is part of a team assisting with Conservation Commission and Board of Health permitting, and the required documentation drawings. It is said that “necessity is the mother of invention.” At Mill River, Marianne prides herself on finding creative solutions to meet or solve difficult situations.
Marianne is a member of the Yankee Onsite Wastewater Association (YOWA).
