O'Neil Events




Colleen was amazing! She was recommended by a friend of mine who also used her for her wedding and it was the best decision I made around my wedding. More than a month before, she collected all of my contracts, reviewed them, coordinated with all of my vendors and hammered out a very detailed schedule which I would have never had the time to do and which allowed us to correct issues in advance. Weekend of she was incredible, kept my stress level low while making sure everyone was in the right place at the right time and that everything ran smoothly. Without her it would not have been nearly as wonderful of a day but with her it was amazing! You wont regret hiring her.



I can not even begin to write how INCREDIBLE Colleen (and the whole company) was during my wedding planning process. She was immediately responsive, always helpful and always calm as we made decisions about my wedding and worked with so many different vendors. I would always say that she was always one step ahead of me. If I thought of something that needed to get done for the wedding, Colleen had already completed it. I appreciated her open and easy communication the whole time. She was always available to help, problem solve, and give advice. She went beyond helping with planning and communicating — she helped me with little things like how to tip the vendors, how to make sure all of my items were accounted for, etc. She made the day 100% seamless. If we had any bumps in the road on my wedding day, I had no idea because Colleen handled everything. Whenever I would get my vendors on the phone or communicate through email, the vendor would always comment that “Colleen has already taken care of that”. She was professional, happy, dependable, kind, thoughtful and hard working. She was a heaven sent when wedding planning and made the day absolutely perfect for me. I would recommend her service to anyone, always.



O’Neil Events came highly recommended to us by our reception venue, Rock Creek Mansion in Bethesda. Our planner Yvi was assigned to us one month before our wedding was to take place. She capably handled communications among multiple vendors and made sure everyone was on the same page, and provided a very detailed timeline for everyone to follow. She also had excellent advice on some planning points, such as transportation for guests and decor, which proved to save us a bit of money here and there. Our service and reception ran so smoothly and we had such a great time from start to finish. While I was initially hesitant to hire an official wedding planner, I am so glad I did….Yvi made the day stress-free and we could focus on enjoying ourselves!



Colleen O’Neil was by far the most amazing wedding coordinator I could have ever had! Months before my wedding she met with me several times to go over details for the ceremony and reception. We had an extremely complicated layout for the reception (cocktail hour, dinner & dancing all in 3 separate locations at our venue) and Colleen made the entire evening go flawless! I had more fun at my wedding than I could’ve dreamed of and that was because Colleen took care of every last detail and allowed me to enjoy my wedding day. She worked extremely well with all my vendors (florist, caterer, photog, videographer, venue, church etc) and I couldn’t be more appreciative for all her hard work and dedication. She is one of the most reliable, detail oriented and trustworthy professionals I’ve worked with. She is a must for your wedding day!



We hired Colleen for month of coordination. Colleen was absolutely wonderful! She was lovely to work with and always responded in a prompt and helpful manner. Leading up to the wedding, she checked in with me and ensured I had thought of all the details and helped me find the answers to just about any question I had. On the day of our wedding, she coordinated all of our vendors and ensured our vision came to life exactly the way planned. I highly recommend her!



Colleen was one of the better vendors we chose during our wedding. Starting from a month out, she was on the ball and persistent in making sure our wedding and ceremony would go off without a hitch. She is very experienced and left no stone unturned during the planning phases. When our big day finally arrived, Colleen and her assistant were like a team of wedding ninjas, quickly jumping from setting up decorations, organizing the vendors, and keeping everyone on track. She was a great investment and we choose her all over again. Thanks Colleen!



O’Neil Events was amazing! Colleen worked with us to make the day perfect even when it meant lots of details and specifications. We felt so comfortable having her around and relied on her heavily to help with every little thing. It was such a weight off of my shoulders and she exceeded my expectations! Thanks you Colleen and O’Neil Events!



We were so happy that we used O’Neil events. We worked with Kristin and appreciated her organization and professionalism throughout our entire wedding planning process. Kristin was excellent on the day of our wedding as well and made sure everything went smoothly. We can’t imagine not having had a day of coordinator and are glad we went with them!



I was hesitant that I even needed a planner but I’m so glad we got one! We had Ariel as our day of coordinator. Her personality was great and she made it seem like we’ve known each other for years. She was so helpful and always available. The wedding went so smoothly and we have her to thank. We spent our day enjoying ourselves instead of worrying about the details. Before Ariel started helping us full time, Colleen was there to answer any questions we had. She was very easy to work with very responsive. Thank you!!! I highly highly recommend them!



O’Neil Events is fantastic! Colleen O’Neil, the owner, paired me with Laurie Themistos to be our day-of coordinator. Laurie started a month out, and she was EXACTLY what I was looking for! Laurie was organized like you wouldn’t believe, friendly but firm (not afraid to give her honest and polite opinion), resourceful, energetic, easy-to-get-along with and a wonderful and genuine person. I am running out of adjectives to describe how great she was–Laurie deserves all of the credit for making our wedding a success. It went off without a hitch!

Colleen O’Neil was super easy to work with and checked in throughout the wedding planning process to make sure everything was running smoothly. I highly recommend using O’Neil events for wedding coordination–they are top notch, and the price is unbeatable as well. Thank you, O’Neil events, for a wonderful wedding experience!



My wife and I were so glad to have hired O’Neil Events for our day-of-coordination. Our coordinator, Ariel, was fantastic from the first day we met to the end of our wedding. She was helpful in the small details of our wedding that we didn’t think about. Ariel made the wedding less stressful for us by working with the vendors and the venue on the wedding details. and making sure she kept us on track with some of our tasks. She was a great person to provide assurance and support throughout the wedding process, even when were predicted to have snow on our wedding day. She would tell us, “Everything will be fine.” And the wedding was very beautiful and successful with no problems. I know we would not have had a wonderful wedding and reception without her. Ariel was the best and I would recommend hiring her and O’Neil Events for any wedding coordination. It’s worth the money! Trust me.



I could not be more excited to share our incredible experience with O’Neil Events and Ariel in particular. From the outset, Ariel put us completely at ease of all the details (big and small) about our wedding day. She was calm, cool, and collected at every turn, was always thinking ahead, and had a plan for everything. Our family and friends are also still raving about what a gem she was every step of the way!
We had a few surprise factors on the day of: complete downpour, two flash mobs, a guest who wanted to propose, I fell out of the chair during the hora…the list goes on. Ariel was right there when we needed her and took care of everything. She made sure everyone was where they needed to be, on time, and made all the moving parts look seamless. Ariel, you made it all look easy and we can’t thank you enough! You are a true gem!

Read what our satisfied clients have to say about their fantastic experiences with our Washington, DC wedding planners. The common theme is that they all felt supported and taken care of by our dedicated organizational experts who were not only super responsive and always one step ahead of them in the details, but who truly cared about them and the smooth execution of their special day.


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. And if you’re in the DC area… have it be Colleen. 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. 🙂



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.  The day of the wedding, she met us at the hotel to check on everyone, took care of personal flower delivery, and made sure everyone was exactly where they needed to be. If anything went wrong, I was completely oblivious to it because Yvi handled it all! 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!



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… from simple oversights like needing extra escort card holders, which she spent her own time buying for us, to the complex, when a family member made a spontaneous and bizarre request during the dinner toasts, Ariel 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.
