Having worked every summer in the family industrial distribution business and having an interest in working in the industry, he attended Texas A&M to obtain a Bachelor’s of Science from the Industrial Technology Department in Industrial Distribution which is a mix of business and engineering curriculum.

After Texas A&M, Eric joined Holloway Bros Tools Inc., representing the third generation of the family to work in the business. Five years later he bought out his father’s interest in the business and proceeded to grow it through acquisition over the next five years before selling beneficially to an industry consolidator, MSC Industrial Supply (NYSE: MSM). Eric had a two-year contract to help integrate the business into MSC but quickly realized he enjoyed the entrepreneurial style of work.

Brett Riley-Design &
Development Engineer

Brett Riley

Brett Riley is a graduate of Temple University with a B.S. in Mechanical Engineering and a concentration in Energy Systems. Fields of interest are renewable & alternative energy systems, HVAC design, and sustainable farming. He has had previous internship experience with a sustainable farming start-up based in Jerusalem, Israel where he helped to design aquaponics systems built out of recycled/repurposed material as an affordable means for families in lower income urban areas to be able to grow their own food.

Brett has also worked on a project to renovate a high tunnel greenhouse at a community garden near Temple University that grows fresh and affordable produce for the local community in North Philadelphia. His team installed a rainwater catchment system to decrease the dependence of municipal water, implemented a passive ventilation system to promote air circulation and better regulate the greenhouse environment, and installed a solar-powered system to provide a source of electricity to power the necessary equipment the farm might require. The produce grown in this greenhouse, managed by the Federation of Neighborhood Centers (FNC) a nonprofit organization focused on youth development and urban farming, provides fresh and affordable food to the local community that would normally not have access to. It has become a continuing Senior Design project for College of Engineering students at Temple University, and Brett continues to work with future groups to improve on the system and efficiency.

Scott Kennedy
Project and Fabrication Manager

Scott Kennedy

Scott joined AirGreen in early 2021 after completing a complex, three-year construction project where, as part of the work, he helped install one of AirGreen’s first commercial units. The project included the redesign and retrofit of an old import vehicle repair garage into a classic car museum, along with the design/build of an adjacent two-story diner. The AirGreen portion of this project was complicated and challenging in that the only space for this equipment was in two separate small mezzanines located above the primary floorspace. We at AirGreen quickly learned to appreciate his comprehensive problem-solving skills during this demanding project, and when the project was completed, we were lucky enough to have him join us and utilize his deep experience to our benefit.

Scott has a well-established fabrication background, having worked for Dewson Construction, as well as running his own custom construction company (Split Line Carpentry) from 1990 to 2016. Prior to that, he was a crew leader for Leroy Fisher Construction, building custom homes. Earlier, Scott drove for Tipton Trucking, and did various mechanical work as well. And to prove that he is a well-rounded individual, Scott has a culinary background also.

When not fabricating new equipment for AirGreen, Scott likes to spend time on his motorcycle and with his family, particularly his four grandsons. Scott grew up in West Grove, Pennsylvania and currently resides in North East, Maryland.
