The events industry is unique in that professionals are essentially free to call themselves whatever they want, there’s no one standard like other career fields. We can be Event Planner Queen, Mistress of Wedding Planning, Head Planner in Charge, etc. This can cause a lot of confusion not only when dealing with vendors, but choosing your event professional could be difficult. While the terms planner and coordinator could be used interchangably, there are fundamental differences in the duties associated with each title.
An event planner is one who helps her clients with all aspects of bringing their event to fruition, The planner does the actual coordinating of all aspects of the event from start to finish.
An event coordinator executes the plan that her clients have put together (call her the Executioner). With regard to weddings, the coordinator is usually brought in during the month of the wedding and she manages the rehearsal, ceremony, and reception. For other events she would handle everything related to the event on the day of the event, giving clients the freedom to relax and enjoy their guests.
The only way to guarantee that you are getting the services you are going to pay for is to make sure the details are outlined in your contract with your event professional, regardless of their title.
