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.
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!”

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.

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!
