From intimate affairs for 30 guests to elaborate weddings for 400, Una has planned them all - from New York to California and destinations abroad.  Her strengths in organization and hospitality paired with a passion for design & fashion help her to create distinctive and memorable experiences. Whether it’s producing beautiful outdoor & tented affairs, creating entirely new environments in blank lofts, or bringing a unique touch to classic landmark hotels & mansions, she applies her creativity and meticulous attention to detail in customizing each event.


Una honed her skills in planning & design apprenticing under some of the best in the industry, eventually serving as a senior event director at Daughter of Design, one of the country's premier event planning firms. With a degree & background in the sciences, she started off her career in the medical field. But rather than pursuing a medical degree, she followed her love and passion for entertaining & design and has never looked back since. She brings the same level of precision, professionalism and strong work ethic to planning weddings & events.

So where did the name come from? Many years ago, Una and her husband had their first date between Sullivan and Prince St. in NYC and the location always held special meaning. Every great wedding starts with a genuine and loving relationship between two people, budding from that very first date. It felt fitting to marry that nostalgia with business and from that, Sullivan & Prince was born.
