"I am confident my wedding would not have been so stress-free if it weren't for her help!" - LAURA
I am so pleased with my decision to work with Colleen for my wedding this past May. In the months leading up to my wedding she was readily available and reliable, always willing to help me work through a question or problem, and helped me stay on track to ensure I completed everything I needed to do on time.
She embraced many roles and responsibilities (went above and beyond) and completed every task nearly immediately as well as meticulously. She helped not only the months leading up to the event feel stress-free but was super relaxed all while making magic happen behind the scenes on the day of the event.
I am confident my wedding would not have been so stress-free if it weren't for her help! Great work, great personality--it's a great choice to hire Colleen to help with your most important life events.

"The day of she was truly someone
we could trust and lean on" - Lianne
I am so happy we worked with Colleen! Highly recommend - she made my life so easy as I was planning from out of town. We just got married at the Village in Stamford and everything ran smoothly and it was a great night!
We booked her Event Management package, 3 months before the event and she helped us with vendors, timelines, and all the little details that are easy to forget. Every detail for the day was planned out to the minute. The day of she was truly someone we could trust and lean on.
She went above and beyond and even helped us deliver a check we forgot the day after the wedding since we would be heading out of town. She really is a pro and we would of been lost without her!

When people ask me for wedding advice, I always say the most important vendor is a wedding coordinator or planner—and I send them straight to Colleen! We couldn't have made it through our wedding year without her. We're so grateful for her expertise, hard work, and, most importantly, her professionalism. My husband and I both work in the city, and Colleen was there to ease our stress as we juggled back-and-forth trips to CT. Having her with me on our big day was invaluable.
Colleen is incredibly organized and creative, and she truly saved the day in countless ways. She created our church programs, organized vendor contracts, proofread everything, built our timeline, and ensured our venue and our rooms were exactly as we envisioned. She even made sure our ceremony was seamless. Colleen met every one of our wants and needs, and she is one of the most dependable people I’ve ever met.
She was there to answer every question—mine, my mom’s, and everyone else’s! Colleen is so kind and charismatic, and she genuinely wants your day to be perfect. With her by your side, it will be!
An expert in the wedding industry, she guided us from start to finish, from vendor referrals to crafting a custom golf cart, to arranging the ballroom and tables exactly as I imagined. Every detail was thoughtfully planned to make our big day perfect.
We also used her rental and decor services, which saved us so much time and stress! She communicated professionally with our vendors, ensured our guests and bridal party knew where to be at every moment, and even coordinated the shuttle service. She was endlessly patient with me during my bridal moments, and we feel so lucky to have found her.
Colleen has her pulse on every single aspect of creating a perfect wedding, and we highly recommend booking her services ASAP—you'll need her!
The Monday after our July wedding, my best friend immediately hired her for her own December wedding! Thank you, Colleen, for everything. We couldn’t have done it without you!
"If we could plan our wedding all over again, the
first thing we’d do is partner with Colleen" - Tara
Colleen and her team were absolutely incredible from start to finish. We initially hired her for her Event Management package, but we expanded her services for support in the months leading up to the wedding.
Countless vendors commented on how detailed and organized she was—one even said, “This is the most amazing planner we’ve ever worked with!”
One of the many reasons we chose Colleen was her expertise with Something Borrowed Blooms, a cost-effective and allergy-friendly flower rental option. She went above and beyond: coordinating the delivery of 12 boxes of florals to her home, inspecting the blooms, fluffing them to perfection, transporting them to the venue, setting each table, breaking them down afterward, and shipping them back. And she did all of this on top of flawlessly organizing our entire wedding day from start to finish.
The level of thoughtfulness and attention to detail Colleen brought to our wedding truly floored us. Because of her, we were able to be fully present, happy, and relaxed on our special day. If we could plan our wedding all over again, the first thing we’d do is partner with Colleen! THANK YOU, COLLEEN!!!

ANYONE would be lucky to work with her. Starting six months out, she was in touch with us regularly, holding regular check-ins and always answering our (many!) questions and emails thoughtfully and quickly.
She really helped guide us through the wedding planning process, not only helping us stay on track with day-of details, but also helping to provide creative solutions when problems arose, like our church double-booking our wedding with another back to back. She stepped in and immediately came up with a plan to resolve the issue.
She communicated with our vendors seamlessly behind-the-scenes and they all complimented how professional and great she was to work with! She also put together the most detailed and comprehensive day-of timeline I've ever seen. I actually had multiple bridesmaids AND wives of groomsmen tell me how amazing it was. This created a truly grounded, and relaxing experience the morning of, where we actually ran EARLY, which has never happened to me in any wedding before. This made for a day that flowed incredibly smoothly.
I was a deeply Type A bride, and I had ZERO (really!) stress or anxiety the morning of because of how much support I had, and how well planned the day was.
She took so much work and stress off my plate because of her support, and I genuinely do not know how I could have planned my wedding without her.
"What stood out most was her dedication to our happiness" - Bridget
My husband and I can't recommend Coll It Entertaining enough! Colleen went above and beyond to bring our dream wedding to life, anticipating our needs before we even knew we had them. Her attentiveness, organization, and professionalism were unmatched.
What stood out most was her dedication to our happiness and ensuring that every detail of our day was flawless—and it truly was. She listened intently to our vision, executed it perfectly, and added thoughtful touches that made our wedding uniquely ours. Her warm, caring nature eased any stress, allowing us to fully immerse ourselves in the day.
Thanks to Colleen, our wedding was unforgettable and a memory we’ll cherish forever. If you're looking for someone who will wholeheartedly invest in making your wedding as magical as possible, look no further than Colleen!

"Her consultative approach during meetings gave us confidence and clarity in every decision" - Amy
I found Colleen through my best friend’s wedding, and I’m so glad I did! Working with her was seamless and stress-free. Weddings come with so many moving parts, but Colleen helped us stay organized and focused, allowing us to relax and truly enjoy the experience.
She created our day-of timelines, managed communication with vendors, and took care of so many details, including designing our menus, table numbers, church programs, and seating chart. Throughout the night, she was our go-to person—anything we needed, she handled flawlessly.
One of the many things that stood out to us was how thorough Colleen is. She thought of details we hadn’t considered, like coordinating the delivery of our cake to the venue, and offered invaluable guidance based on her experience. Her consultative approach during our meetings gave us confidence and clarity in every decision.
We highly recommend Colleen for any event. She’s an absolute joy to work with and truly exceptional at what she does!

"As a venue that specializes in DIY weddings, having
a person like Colleen to keep things
organized and stress-free is crucial" - Erik
Photographer & Co-Owner at Wild Sugar Homestead, Hallie Leonard:
I worked with Colleen for Madi & Wade's wedding at Wild Sugar Homestead in Vermont in August of 2024 and she was INCREDIBLE. As a photographer, the task of following an itinerary and herding people from one thing to the next often falls on our shoulders. But Colleen took all of that pressure off and was very hands on during the day, gently guiding people to stay on task and on time. The decorations and design were beautifully curated and put together. I highly recommend booking Colleen!!
Co-Owner at Wild Sugar Homestead, Erik Calderone:
We absolutely loved working with Colleen for Madi & Wade's wedding at our venue, Wild Sugar Homestead. She was thorough and communicative leading up to the event and such a big help the weekend of. As a venue that specializes in DIY weddings, having a person like Colleen to keep things organized and stress-free is crucial. We would love to have her back!

Church Coordinator for St. Gregory the Great Catholic Church, Melissa:
Colleen was amazing to work with. She is extremely organized and had everything planned down to the second, which was extremely necessary with such a large wedding party. As the wedding coordinator for the parish, it was a pleasure to work with her and learn some new ways of organizing the ceremony, etc. I wish she lived closer so we could work together more often. Extra stars because Colleen handled the rehearsal and ceremony and all the chaos, all while being close to her due date! She is a rockstar!
