O U R M I S S I O N
Mosaic’s mission is to provide an elegant space and effortless service that make guests feel seen and celebrated. We embrace fresh perspectives, bringing your vision to life in ways that feel personal and unforgettable.
OUR STORY
Mosaic Venue was founded on the belief that every celebration should be a true reflection of the people behind it. When owners' Phuong and David O’Neil planned their wedding over a decade ago, they struggled to find a venue that would allow them to merge their cultures—especially when it came to food. Phuong, who immigrated from Vietnam as a child, and David, a Minnesota native and military veteran, wanted a space where their families could come together without barriers. The challenge of finding a space that could accommodate their specific needs inspired them to create Mosaic.
At Mosaic Venue, we embrace an open catering policy and offer flexibility. We believe every event should be as unique as the people hosting it. Our approach allows clients to bring their traditions, flavors, and cultures to life—without strict restrictions. Whether it's a wedding, celebration, or gathering, Mosaic is a place where all stories are honored, and all guests feel at home.
