A TRULY CUSTOM EXPERIENCE

BEVERAGE PLANNING,
EVENT SET UP & TEAR DOWN

From creating a custom drink menu to providing personalized bar setups and professional staffing, our experts will work with you to create a truly one-of-a-kind experience for your guests no matter the event!

We understand that planning an event can be stressful. That's why we take care of all the details — from event set up to tear-down and even offering vendor coordination or recommendation assistance.

A day-of coordinator focuses on managing the logistical details and ensuring the smooth execution of an event specifically on the day of the occasion. Their responsibilities typically include overseeing the setup of the venue, coordinating vendor arrivals and activities, managing the event timeline, and addressing any unforeseen issues that may arise during the event. Day-of coordinators play a crucial role in executing the pre-established plans, allowing clients and other event stakeholders to relax and enjoy the event without being burdened by operational details.
