How We Make Your Life Easy

With over 15 years of experience as a wedding planner in DC and NYC, we know what works.

We listen to what matters to you, what does not, who needs to feel included, and what kind of night you want to remember in ten years. Then we turn that into a clear plan you can trust.

Your vendors are curated, not just based on who we’ve worked with in the past. We create the team that’s the best fit for you and the venue. Our team breaks down proposals and contracts in plain language, keeping an eye on the fine print so there are no surprise add-ons later.

You get the best of our relationships without losing control of the choices.

Whether you choose our full-service wedding planning or month-of coordination package, we ensure that our communication is consistent, your guests feel welcomed, and you can be present without wondering if anyone remembered to email the caterer.

The calmest and most supportive planner I could have asked for!

“Colleen was so amazing to work with! She was patient, supportive and flexible every step of the way. I could truly enjoy my wedding day without a single worry and so could my family. The entire day was perfect and if anything did go wrong, I didn’t have a clue. She took care of every detail with a sense of calm that put me at complete ease! I can’t thank her enough and would recommend her to anyone planning a wedding!!”

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.

The Absolute Best!!

Working with O’Neil Events was the best thing I did to plan my wedding! Colleen and her team are incredible – they have a calming, efficient, and professional communication style. Colleen and her team are incredibly knowledgeable, organized, and provided incredible value. She kept us organized from the beginning of the planning process through the entirety of the event, making sure everything ran smoothly. She coordinated with our vendors and did not miss a beat on anything. She thought of everything and ensured the planning process remained fun and not stressful at all. We couldn’t be more thankful for O’Neil Events – you will not be disappointed!

Fabulous Wedding Planner!

From the moment we booked O’Neil Events, we knew we were in amazing hands. Colleen and her team were incredibly professional, attentive, and caring throughout the entire planning process. They worked efficiently to create an individualized and organized experience for us. Colleen connected with us regularly to ensure we had an effortless planning experience, and our day-of coordinator, Yvi, was simply phenomenal – she brought us appetizers and made sure we had a moment to ourselves when we really needed it. I cannot recommend Colleen and her team at O’Neil Events highly enough!
