DC Wedding Planner & Coordinator
You Celebrate, We Run the Show
Planning a wedding in Washington, DC comes with its own challenges, from family expectations to navigating permits and out-of-town guests. At O’Neil Events, we handle the hard stuff so you can enjoy your celebration. With 15+ years as a DC Wedding Planner, we plan elegant celebrations that honors your tradition and still feel like you.
You’re juggling a lot, let’s see if we can help
Most DC couples we work with are managing demanding jobs, travel plans for guests, and family members who (lovingly) want to weigh in on every decision. Add in the logistics of rehearsal dinners, ceremonies, and brunches, and it gets overwhelming fast.
You don’t want to spend your engagement buried in spreadsheets or having your parents or friends running around troubleshooting on your wedding day. You want a plan, a point person, and a day where your parents and friends are free to be guests.
Tell me, what kind of support are you currently looking for?

We’re OFFER CALM AND HONEST GUIDANCE
As a DC wedding planner, we know the ins and outs of the city, from iconic venues on the Hill to tucked-away Georgetown gardens. We’ve built strong vendor relationships and mastered the details so you don’t have to.
When you hire O’Neil Events, you are not buying a checklist. You get calm, honest guidance when a choice actually matters. We work to protect the flow of your day so your grandmother is seated comfortably, your best friend does not spend cocktail hour chasing the Photographer, and you can actually taste the dinner you paid for.
HOW WE CAN WORK TOGETHER:
We offer two clear paths: Full-Service Wedding Planning for couples who want a partner from day one, and Month-of Coordination for couples who want to hand things off when it matters most.
Hi, I’m Colleen —
Born & Raised Washingtonian, Calm Under Pressure
I know DC like the back of my hand. From Capitol Hill venues to private estates in Potomac, I’ve planned it all. I bring local expertise, trusted vendor relationships, and the kind of calm presence you’ll want in the room when timelines and family dynamics collide.
Before weddings, I was a Division I lacrosse player, so yes, I thrive under pressure, know how to run a team, and will always keep things moving with strategy and grace. Combine that with over 15 years of planning experience, and you’ve got someone who knows how to balance elegance with practicality.
✨ Fun Facts:
I run on Diet Coke (large, always).
Dessert is non-negotiable — every meal deserves it.
I’ll plan your rooftop photo session but won’t look down (heights are not my thing).
My toddler and cats keep me on my toes — and remind me daily that staying calm matters.
Shoes are my love language (hence the background photo)
