Jeff S. Cosman

Chairman & Chief Executive Officer

Jeff Cosman has had a lifetime experience in the solid waste industry from local operations up to corporate accounting and finance. In the early years, Jeff Cosman began to learn the waste industry business from his father who at the time was a Regional Vice President at Browning Ferris Industries, Inc. ("BFI").  He holds a B.B.A. in Managerial Finance and Banking & Finance, as well as a Bachelors of Accountancy from the University of Mississippi.  He was drafted by the New York Mets and played professional baseball in the minor leagues from 1993-1996.  Jeff Cosman is the youngest son of Jim Cosman, Sr., former President & COO of Republic Services.

In early 1997, Jeff Cosman joined his father at Republic Services as a Controller for a local operation in Chesapeake, VA. Later that year, he joined his father at the Corporate office in Ft. Lauderdale to join a small corporate finance team which played an active role in the consolidation efforts as Republic Services acquired 168 companies in 30 months, going from $500MM in Revenue to over $2.1BN.

Leaving Republic after the company completed its spin-off from Republic Industries; Jeff Cosman spent 10 years in various leadership roles within the startup/emerging medical device industry.  In and out of the medical device industry in the early 2000's, Mr. Cosman began his trail of entrepreneurial endeavors starting with Market Street Capital, JC Waste Solutions, Legacy Waste Solutions and Dynamic Molecular Solutions. In 2012, he purchased a small telecom materials and parts distribution company in Japer, GA, which has now grown to supply customers all over the US.  In April 2015, Mr. Cosman and his wife Rachel bought their partners out of the business and wholly own the business as Rosewood Communication Supply.

In 2010, Jeff Cosman began formally working on creating mobile apps with the development of cConnects.  cConnects is a pioneering enterprise solution that enables internal organizations to connect with external customers and vendors based on established rules, guiding principals of saving time without spending time scheduling events and that can be delivered through app based installs without the hassle of large custom enterprise builds which are costly.

Jeff Cosman has long been inspired by his father's expertise in the waste industry. As a backdrop, prior to Jim Cosman, Sr. passing away in 2013, he spent years under his guidance and oversight in their daily travels at Republic Services and their individual consulting businesses.  Mr. Cosman Sr. focused on "Doing Things Better" daily.  He believed in bringing transformative technology to a simple business model like the garbage business.

Jeff Cosman owns the control-voting block (Preferred A) of MRDN as well as he is the majority common shareholder.
