He came to Miami in 1969 and joined with E.P. Bernuth, owner of New York based Bernuth Lembke. Equipped with Bernuth's finances and Capt. Monocandilos' experience and tireless effort, Bernuth Marine Shipping and Bernuth Agencies developed into a dynamic agency and stevedoring concern.

Capt. Monocandilos and Bernuth worked together building the agency until Bernuth's death. In the years suceeding his partner's death, the Captain continued to expand the Bernuth companies. He also formed a network of businesses related to the maritime industry that complemented the agency's services.
Some of these include a trucking company, a marine mechanical repair shop, welding services, and a tugboat company.

Apart from his involvement in marine transportation, Captain Monocandilos was also an investor of Commercial Trust Bank. From 1988-1994 he served on the loan committee, executive committee and board of directors assisting in expanding the bank's holdings from approximately $23 million to $130 million. Commercial Trust was sold to Intercontinental Bank in 1994.

In 1999, the Captain embarked Bernuth on a bulkshipping venture. The management and operation of two handysize bulk carriers have further broadened the group's scope. These vessels are employed in the bulk grain trade between U.S. Gulf ports and Latin America.

Captain Monocandilos' other holdings include extensive accreage along the Miami River and surrounding areas and residential real estate in Marco Island, FL and Steamboat Springs, CO. He serves as a trustee of the Greater Miami Chamber of Commerce and is an active member of the Propeller Club of the United States, the Miami City Club and the Key Biscayne Yacht Club. Captain Monocandilos is also a member and supporter of St. Sophia Greek Orthodox Church.
