As the third-generation leader of the firm, Lloyd Yeo said, “My great grandfather, Thomas Yeo came to the Americas from England in the late 1800s. It was said that he took the name YEO which was a derivative of the name yeoman.” The English word “yeoman,” means attendant, in the royal household regarded for loyal, vigorous, and effective service.
