Westbrook, Maine – April 8, 2025
The Regional Transportation Program (RTP) is proud to welcome Sadie Donnell and Don Ladd to its Board of Directors. Their extensive backgrounds in community advocacy, public policy, education, and nonprofit financial leadership will strengthen RTP’s efforts to deliver accessible, equitable transportation across Cumberland County.

Sadie owns and operates Maine KwiqiMart, a small business launched in 2023 that manages vending and micro-markets in the Portland area. Her advocacy extends to public infrastructure through her involvement in Mainers for Smarter Transportation and the Moving Maine Network, where she collaborates on policy, planning, and legislative advocacy. She’s also worked with Disability Rights Maine and the University of New England to train future healthcare providers on disability inclusion and lived experience.
