Raina Rippel

Executive Director

Raina joined Communitopia as the Executive Director in May 2022. She started her career as an Executive Director in 1999 for Physicians for Social/Responsibility Maine Chapter, and has since served as the senior Director for multiple organizations and is well-versed in start-up activities. From 2011 - 2020 she served as the founding Director of the Southwest Pennsylvania Environmental Health Project. During her tenure she was the recipient of the 2016 Jean and Leslie Douglas Pearl Award, and the 2020 PennFuture Woman of Environmental Justice Award.

When the COVID pandemic started, she spent a year working on the front lines of public health as a Case Investigator, contracted with the PA Department of Health. She then consulted as a Senior Fellow for the Halt the Harm Network, a nationwide network of grassroots leaders working to solve the myriad problems coming from the oil & gas industry and fracking.

She is a proud mom of a girl and boy, and lives south of Pittsburgh in Venetia, PA. Thanks to her son she has rediscovered her love for soccer and long bike rides (which she never forgot to love). Thanks to her daughter, she gets to see more online dance moves and memes than she ever thought she would.

As a military daughter and avid traveler, she has lived in or visited nearly every state in the country, as well as living for six months in Australia, so she looks forward to sharing her myriad stories with a new audience of committed climate activists.
