I’m a DC native with deep industry connections, but NYC is in my blood! My mom grew up in the city, and I spent holidays and school breaks there with my grandparents. Whether you’re dreaming of an elegant DC soirée or a chic NYC celebration, I’ve got the insider knowledge to bring your vision to life.

SO SWEET & CARING
My husband and I said SEVERAL times how having Colleen by our side as a Day Of Planner was way beyond worth the money spent. If I have one recommendation for any newly engaged couples, it’s have a day of planner. From the beginning just getting coffee with us and helping us start the process or planning, to every living detail of the day of… I can’t imagine our big day without her. She was immensely professional. So sweet and caring; yet I knew she’d get done what needed to be done. She’s no pushover! Monthly emails and check ins were lovely and kept us on track. But then the month leading up to the wedding, Colleen took everything off my plate and handled all the logistics and vendors and timelines.
So, so valuable. Thank you for everything you did! We’ll both never stop raving about you. 🙂

THE FAIRYTALE I DREAMED OF
O’Neil Events came highly recommended to us by our caterer, and hiring them was one of the best decisions we made for our wedding! Yvi & Colleen were both responsive via email and easy to work with. The month of our wedding, Yvi took everything over and was positively wonderful! She contacted all of my vendors and was able to coordinate things behind the scenes that I didn’t even know about. If anything went wrong, I was completely oblivious to it because it was handled! She was organized and on top of everything that day and helped to create the fairy tale I had dreamed of!
If there’s one piece of advice I will give to any future bride who asks, it is the value of hiring an excellent day-of-coordinator. Our wedding party and families (as well as us) were able to just relax and enjoy taking in the entire day with the knowledge that Yvi had everything handled. I definitely gained a new friend through the experience!

WE WERE IN SUCH GREAT HANDS
From the minute we met our wedding coordinator, we knew she would be our biggest ally on our wedding day. But we owe her a debt of gratitude for just how much she did — before, during, and after. Everything we conceptualized came to fruition because of her, and never did we feel like we were flying solo. She championed our whims while making sure everything was practical and achievable.
We were in such caring, diligent hands, even when it came to things we forgot, She handled everything with ease, grace, and most incredibly, a smile on her face. She kept everyone in line from start to finish, vendors and family members and the bridal party. Her energy, her excitement, her sheer passion for what she does helped us create and execute a truly perfect day.
