ProStack welcomes Jason Bieber to the role of Regional Sales Manager, bringing more than three decades of industry expertise spanning rental operations, equipment sales, technical training, warranty administration, and field service.
Jason’s career began in 1993 following his service in the U.S. Navy, when he entered the equipment rental industry. Over the next 15 years, he worked with both independent and national rental companies while also selling construction equipment. In 2008, he began working in training, warranty, and field service roles, where he spent 17 years. Most recently, Jason served as a Parts & Service Representative for underground mining equipment before joining ProStack in November 2025.
"I look forward to leveraging my experience to support our dealer network," said Jason Bieber. "While I'm new to ProStack, I'm not new to understanding the needs of equipment dealers. I'm here to help grow the ProStack business in any way I can."
As part of the restructuring, Alex Cacabelos will transition to focus exclusively on the Marco business beginning in January 2026, where customers are encouraged to direct all Marco related inquiries. Everyone at ProStack appreciates the outstanding contribution that Alex has made to the ProStack business throughout the year.
Lee Nesbitt will continue in his role as Global Sales Manager, supporting Canadian dealers and rest-of-world markets for the ProStack business.
