We’re passionate about helping you Transition Local Communities
The Team
Co-Founder & CEO
In 2016, after spending 20+ years in the software industry, Dean made a personal decision to shift his focus to sustainability. Specifically, he wanted to focus on inspiring people to take action—showing them how to live a more eco-friendly lifestyle. After studying a variety of residential engagement models and approaches, Dean and team developed the core of the Green Community Catalysts model that we have today. In 2020, Dean led two fairly significant citizen engagement projects. One was the development of a 4 year, 5M Euro, 14 member team EU Green Deal proposal to pilot citizen engagement across 6 diverse cities and regions in Europe and the second was a 4 town, residential engagement sustainability program located in the Upper Valley of NH/VT. In 2021, Dean was asked to deploy the model in his hometown, Beverly MA, and has led to what Green Beverly has become today.
Dean believes that taking a systems based approach to residential sustainability engages the broadest spectrum of individuals and yields the greatest impact. Dean also believes that it's not only important but critical to engage the community in an equitable and inclusive manner. We can not solve this climate crisis with 10% of the population, it requires 100% of the population.
In addition to spending time with family and friends, Dean enjoys working on their 1888 home, staying in shape at the local CrossFit, and periodically exploring the underwater world with some scuba diving friends.
