Simply the Best
Simply could not recommend O'Neil Events, and specifically our planner Christina Sin more highly. My venue connected me with Colleen initially and from our initial phone call I felt immediately at ease. Wedding planning is stressful, no way around that, but even though we had only booked O'Neil for a month-of package, she stayed in touch periodically from the minute we signed on. When Christina, our coordinator took over, it was like a major weight was taken off my shoulders. My entire wedding party and family were immediately put at ease by Christina, as were the other vendors. Christina was endlessly calm and kept a permanent smile throughout the process, keeping track of every detail and making sure that I really could sit back and enjoy the day almost like a guest at my own wedding. When I forgot to grab my change of shoes for the reception, she actually drove back herself to the hotel to bring them to me. She was ever present, but also hung back to let us live in the moment. After the wedding, Christina packed everything up with care and inventoried everything we needed to pick up from the venue. She was indispensable, and yet made it all look easy. I couldnt recommend O'Neil Events more and particularly Christina - thank you for giving the absolute wedding weekend of our dreams.
Response from vendor•Feb 17, 2026She does have the best smile! So glad to hear you were able to really enjoy your special day!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! :)
Response from vendor•Feb 17, 2026You are amazing! What a great day and so excited to have met your special little guy!Stress-Free Wedding Thanks to O'Neil Events
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!
