Who We Are

Thomas Jongert grew up learning the recycling business with several siblings, as his father was one of the founding partners of Rocky Mountain Recycling. Thomas worked in several areas of the company during his teenage years. Thomas left the Salt Lake City area to attend college in Chicago and returned to Rocky Mountain Recycling to manage transportation and processing operations in the Las Vegas area for one year. Thomas increased his value to the company with a commercial driver’s license and progressed from driver to dispatcher to Transportation Manager. In 2016, Thomas returned to processing and became the Director of Plant Operations. When Rocky Mountain Recycling became Rocky Mountain Recycling Services and operational demands shifted, Thomas became the South Salt Lake City Plant Manager to oversee the vast majority of single-stream processing and shipping. As the company continued to grow and manpower needs realigned, Thomas was named the General Manager of the company in 2025.

Thomas enjoys spending time with his family and appreciates the outdoors. Some of his favorite activities include scuba diving and boating. He is also a big fan of salt-water aquariums and is an aficionado of home tanks.

Marvin grew up in Murray, Utah, a suburb south of Salt Lake City. He learned early to turn his hobbies into income, and his first job was at Mick Riley Golf Course. This job provided not only a wage but also free golf and access to some great people. Marvin enjoys camping, hunting, golf, mountain biking, and spending time outdoors with his family.

After marrying his wife Kim, Marvin took a job as a driver at a small recycling company called Utah Recycling. He figured this would be an excellent job to hold while he finished school. Marvin got to see many different aspects of this business as he worked his way through school and started his family. Through some hard times and long hours, Marvin attained his degree from the University of Phoenix in 1997 in Business Administration while still working for Utah Recycling.

In 1999, Allied waste acquired Utah Recycling; to Marvin, this didn’t seem like a good fit. Some key members of management had plans to start up their own business. Marvin was fortunate to find a way into this group, and they formed Rocky Mountain Recycling in late 1999. This business had its ups and downs, but after nearly 21 years was sold to CellMark, with whom they worked in partnership for many years.

Marvin provided strong leadership as General Manager of the new Rocky Mountain Recycling Services Company for five years.  Due to aggressive growth planning, Marvin became the Director of Business Development in 2025 to ensure the future success of the company.
