Meet The Mechanical Team

Jeff Castellani

Director of Mechanical Operations


Jeff Castellani serves as Director of Mechanical Operations at SOLitude. He leads SOLitude’s mechanical division with invasive weed control services, surveys, reports, proposals and GIS mapping. Jeff is a licensed applicator in many states across New England and maintains licensing and industry certificates for Construction Supervisor, OSHA, Qualified Rigger and Signal, as well as Boater Safety. 

Jeff is a graduate of Southern New Hampshire University and holds a degree in Business Studies with a concentration in Finance. He spent the first 16 years of his career in banking and worked as a branch administrator, training manager, merger and acquisition project manager, and commercial loan liaison, and eventually obtained Vice President status. In 2001, Jeff left the banking industry to pursue a new challenge and spend more time with his family. He obtained a Massachusetts Construction Supervisor License, after two years of rehabilitation experience with commercial and residential properties. With a desire to excise both his intellect and body – and also work outdoors - Jeff accepted a position with his neighbor’s environmental company. His environmental and biology experience was gained both on the job and self-taught. Jeff saw an opportunity to expand the mechanical method of aquatic vegetation control and detritus management, and that evolved into his current position. He is driven by developing career paths for individuals, and providing an excellent customer experience. 

Jeff is a caring father and husband. When not at work, he likes to spend time with family and friends, freshwater fish and pursue oceanfront activities. Jeff also enjoys helping out the community by coaching his local Pop Warner and Little League teams. Not quite able to give up his financial background, he also serves as the treasurer for both youth sport Boards. Jeff values helping to develop core principles and skills in young men and women. He takes pride in any endeavor presented, and looks at each challenge as an opportunity rather than a problem.
