Wedding planning feels like too much — because it is

You’re juggling a career, family, a social life (if you’re lucky), and now… hundreds of wedding decisions. Which venue is worth it? Which vendors actually deliver? How do you keep the peace between your parents and your in-laws?

Here’s the truth: you shouldn’t have to spend your engagement glued to spreadsheets or putting out fires, let alone the wedding weekend.  Your family and friends shouldn’t be your day-of coordinators. And you definitely shouldn’t be answering vendor emails at midnight.

“Working with O’Neil Events was the best thing I did to plan my wedding! Colleen and her team are incredible- she made the entire wedding process seamless and smooth! Colleen helped turn my visions into a reality for my wedding- she is beyond organized and kept me on track while planning through it all! We couldn’t be more thankful O’Neil Events! You will not be disappointed!”

Meet the Owner – COlleen

I’m Colleen O’Neil Phillips – DC (on my Dad’s side) & NYC (on my Mom’s side) native, with Diet Coke in my veins. I’m a former Division I lacrosse player turned wedding planner, which means I know a thing or two about keeping calm under pressure and leading a team to victory.

Diet Coke is my love language

I hate board games – too competitive. Weddings, however, I always play to win

“I worked with Colleen for our wedding and she was so helpful throughout the process. She had good advice coming from years of experience and was always communicative and quick to respond. She made the whole wedding day feel easy and smooth and I am so glad we made the decision to work with her!”

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!
