By 1943, it was incorporated as a limited liability company and its brand had grown to become one of the popular food retail and wholesale operations in the south of the country.

Over the subsequent decades, the company grew rapidly developing several landmark real estate projects and expanding its supermarket operations.

He was orphaned at an early age and through the assistance of extended family he moved to Hong Kong to work with the Allum’s family. By 1932, he accepted an invitation to work in their family’s business located in Trinidad, West Indies.

Once settled in Trinidad, his strong work ethic allowed him to gain the confidence of management and as a result he was invited to become one of the original partners in J.T. Allum & Company. It was during these post-Depression and pre-World War II days, that business was extremely difficult but Mr. Mack persevered and built a thriving business operation. By 1956, Mr. Mack became its main shareholder and began an aggressive and successful expansion of the group’s retail and real estate businesses.
