Collie Greenwood, General Manager and Chief Executive Officer of MARTA, has announced his early retirement following the expiration of his work permit on June 18, 2025. Greenwood, a Canadian citizen, remains in the United States legally while awaiting his permanent resident card.

Out of an abundance of caution, Greenwood ceased working upon the expiration of his employment authorization document and personally informed MARTA’s board members and executive leadership. He also signed a delegation of authority to Rhonda Allen, the Chief Customer Experience Officer, who has been named acting General Manager and Chief Executive Officer.

“My wife and I have decided this is a good opportunity to take an early retirement and spend more time with our family and friends,” Greenwood said. “I do want to thank the board, the executive leadership team, and everyone at MARTA for their support and their continued work to improve and grow transit service in this region.”

Greenwood joined MARTA in 2019 and became General Manager and Chief Executive Officer in January 2022. During his leadership, MARTA earned its highest bond rating and advanced major projects, including the region’s first bus rapid transit line, a systemwide rail station rehabilitation project, and a new fleet of railcars. MARTA also received the 2024 Outstanding Public Transportation System award from the American Public Transportation Association.

“Collie came to MARTA with a tremendous knowledge of transit and an innovative mind and has led the Authority through some challenges and great successes. My fellow board members and I are thankful for his leadership and wish him and his family the best,” MARTA Board Chair Jennifer Ide said.

The MARTA Board of Directors will form a committee to begin the search for a new General Manager and Chief Executive Officer.

We live in a time when information feels overwhelming, but here’s what hasn’t changed: facts exist whether they comfort us or not.

When A&W launched their third-pound burger to compete with McDonald’s Quarter Pounder in the 1980s, it failed spectacularly. Not because it tasted worse, but because customers thought 1/3 was smaller than 1/4. If basic math can trip us up, imagine how easily we can misread complex news.

The press isn’t against you when it reports something you don’t want to hear. Reporters are thermometers, not the fever itself. They’re telling you what verified sources are saying, not taking sides. Good reporting should challenge you — that’s literally the job.

Next time a story makes you angry, pause. Ask yourself: What evidence backs this up? Am I reacting with my brain or my gut? What would actually change my mind? And most importantly, am I assuming bias just because the story doesn’t match what I hoped to hear.

Smart readers choose verified information over their own comfort zone.
