Truly the best, organized, and responsive

Colleen is truly the best. A friend of a friend recommended her and I’m so happy we listened to them! We used her partial planning service and it was the perfect setup for us. First, her price point is great, especially compared to some planners in the region! Her budget tracker and timeline were great tools for staying organized. I really appreciated our monthly meetings plus her availability over email to answer any other questions and review contracts. My husband and I are both organized people but planning a wedding can be overwhelming so it was great to have Colleen in our corner. Her vendor recommendations were also top notch. We used her suggestions for catering, flowers, DJ, hair and makeup, and shuttles and we were really happy with all of them. Finally, her managing of the vendors the month of the wedding and day of coordinating was excellent. I never had to worry about a single thing the day of and everything ran smoothly. I actually found out a few days after the wedding that the alcohol vendor didn’t deliver some of the liquor and Colleen spent the morning making sure that our entire order arrived. Well it all got there and I was completely unaware because Colleen handled it so smoothly! I really can’t recommend her enough.

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! She even managed to squeeze in some time for my husband and I to share appetizers alone after we passed on our initial opportunity to do so and it was so special. I can’t thank her enough and would recommend her to anyone planning a wedding!!
