  • AMAZING Service!!

    INCREDIBLE! Colleen was a dream to work with. Starting with our prep phone calls 6 weeks out, Colleen kept everything on track so I could actually enjoy the wedding planning process. She has a vast knowledge of experience, an eye for detail, and is completely unflappable. When my caterer showed up with one bar set up instead of two, she rearranged the layout on the fly to make everything work. She is kind, positive, and a calming presence. I would not have been able to be so deeply present and enjoy my wedding so much without her. My wife and I agree this was the best money we spent. Hire her! :)

    We had Colleen and Yvi as our month of coordinator, and they were amazing! Colleen helped us nail down the timeline and was always one step ahead, taking care of things before we even realized we needed help. During the day of, Yvi communicated with everyone: vendors, guests, the bridal party; and made sure everything ran smoothly without a hitch. If you're looking for someone who can keep everything on track and handle all the details without you stressing, we highly recommend O'Neil Events. They were a total game changer for our big day!

    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!

    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!
