Sean Diamond is running for the 9th Middlesex House District in Massachusetts as a candidate affiliated with the Forward Party. His professional career has been rooted in sustainability, clean energy, and climate change initiatives, and he believes that we have the technological solutions to climate change - we just need the political will to pursue them.

Sean grew up in a deeply Republican section of Pennsylvania and has lived most of his adult life in a deeply Democratic part of Massachusetts and has never felt at home in either party. He’s been registered with both at one time or another for tactical reasons but has always felt politically homeless. He then found the Forward Party in 2022 and by 2023 became the MA state leader. Deciding that Forward needed to lead by example in MA, he decided to run for office to offer people an alternative to the one-party rule in Mass.
