MCCG-Guyana is a 25 year old alliance of firms providing professional services in Guyana, the United States, Africa, the Caribbean and South America. The firms trace their history back to 1920 in Guyana when John Martin along with local miners (Martin, Viera, Motley, Eytle) started their first commercial venture at Banana Landing.

Later John’s sons Freson and Wilfred established themselves as the principal suppliers to the US Air Corps in Guyana during WWII and subsequently as the Owners of the First Sanitary Laundry in Guyana and the owners of the Tree Light Cafe on the family property in Charlestown.

In the 1970's, MCCG’s predecessor company introduced international contractors and worked on project development teams for the multi-million MMA, Tapacuma, and Mabura projects in the counties of Demerara, Essequibo, and Berbice.

The business opened in the US in 1980's and MCCG was started in 1990 in New York, providing management consulting, project management, and international business services. In 2000, ARVO was started as a commercial real estate affiliate to the company. In 2015, MCCG added oil & gas and agricultural services to its list of offerings.
