Known as The City Beautiful, Coral Gables stands out as a planned community that blends color, details, and the Mediterranean Revival architectural style. Coral Gables is a major employment center, with almost as many people working in the City as living there. The Coral Gables economy is comprised of local and international businesses, but unlike other parts of Florida, it is not influenced as strongly by seasonal shifts. The City is especially desirable to businesses because of its proximity to Miami International Airport, the Port of Miami, and downtown Miami, while also being convenient for executive housing. In addition, a vintage style trolley connects many of the commercial districts, Grand Avenue and the Metrorail. The City has a strong offering of banking, investment institutions, health care, and professional services, as well as being the international headquarters for Bacardi and Del Monte Fresh Produce. The University of Miami (UM) is also located in Coral Gables, and is the City's largest employer. UM, a research university, is ranked 50th among the nations top-tier institutions in the U.S. News & World Report ratings of "America's Best Colleges." Also located within the City is Northwestern University's prestigious Kellogg School of Management Executive MBA Program. Coral Gables' lower schools offer strong academic and international programs including an international baccalaureate program at Coral Gables Senior High and at Gulliver Preparatory School. The City provides excellent municipal services, including an accredited Police Department, as well as a Class 1 Fire Department and a Class 1 Building Division. In addition, Coral Gables has been named a Tree City USA for the last 31 consecutive years, and selected as a Playful City USA for eight years in a row. Excellent municipal services, high quality of life, convenient access, responsible growth and a diversified economy make Coral Gables a highly desirable place to live, work and play.
