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)

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.
