Exact dates lost to history, Paul Gavrity served on CET’s board for at least 25 years, as Chair for at least 20, and at the request of the current Chair, stepped in as Treasurer in the spring of 2022.

Paul has been a steadfast helper, supporter, and leader of CET as it has grown and transformed from a local pioneer to the national organization that it is today.  Among his many accomplishments, he has contributed countless ideas and advice for operational and financial policies and procedures, led the board as it professionalized and adopted best practices, and served as a stalwart leader as CET adopted and executed a bold strategic plan in 2017.

Paul has been an invaluable resource and advisor to CET’s current Board Chair and Executive Committee, providing important institutional knowledge and sound advice. Paul has been a helpful, kind, calm, and practical presence for many, many years. The Board appreciates and is indebted to Paul for his long and dedicated service and many contributions to CET.


Kit Dobelle has served as a Board Member for 17 years and CET has benefited immensely from her wealth of board and organizational knowledge and experience nationally and locally.  She is among the cohort of board members who helped guide CET on its journey from a small, local nonprofit to the fast-growing and even more impactful organization it is today—all while maintaining its nimble, entrepreneurial roots.

Astute on matters of politics and policy, Kit has helped CET’s leadership to understand how CET fits into that landscape and how it could be most effective. Kit has also been an important resource for business development and funding opportunities, generous with her significant network and introductions and her time and participation in meetings with foundations.

Always kind, helpful, supportive, encouraging and fun to brainstorm with, the Board appreciates and is indebted to Kit for her dedicated service and many contributions to CET.


Steve Sears has served as a Board Member for nearly a decade and has helped to steer and support CET on its path to mature and professionalize and become the respected and effective organization it is today.

Steve has been instrumental in making important introductions to his many connections and in helping to secure funding by participating in meetings with foundations.

Always offering thoughtful and insightful questions and advice for board and staff, delivered respectfully, the Board appreciates and is indebted to Steve for his dedicated service and many contributions to CET.
