Wedding planning shouldn’t feel like a second job
You’re juggling a career, family, a social life, and now… hundreds of emails and a never-ending to-do list. 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: your engagement should be the softest part of your story.
This is your time to show off your wedding ring, dream up wedding details and be excited about what’s ahead. It should not feel like a second job.
That’s where we come in.
Simply the best!!
“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!”

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!!”

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.

Dessert isn’t optional
Heights? Hard pass. I will enjoy your rooftop view with eyes firmly on the wall
Diet Coke is my love language
I hate board games – too competitive. Weddings, however, I always play to win

Best wedding planner!
I can’t say enough about Colleen O’Neil and her team. I worked with Yvi and she was the most wonderful person to work with from start to finish. She was amazing on our wedding weekend and kept me calm and organized. She handled everything with ease and allowed me to enjoy our special day. I can’t recommend the team enough, you won’t be sorry for booking them!
