Absolutely amazing!

I cannot say enough about McKenzie. She was the absolute best investment I made for my wedding. She took care of all the details the month of and made sure on my big day I didn’t have to worry or do anything. She always checked in and made sure I was doing okay. She was flexible and knew exactly what she was doing. She executed my vision perfectly and was just such a joy to work with. She helped ease my anxiety which was more than I could’ve asked for. I would recommend her a thousand times over

Peak Coordination

Working with Kenzie was a dream. She was incredibly kind and thoughtful in every detail behind our day. We appreciated her ability to travel to Colorado and her help in envisioning our perfect wedding. She helped to make our small elegant woodsy dreams come true in the middle of the White River National Forest. We are thankful for her coordination during our weekend. Bringing vendors together and creating a wedding in a space with no power or running water takes a lot of work, Kenzie made it look effortless. As a type A person giving up control for a weekend is difficult, but Kenzie made it feel easy. Everything ran perfectly with Kenzie keeping the flow moving of the day. Walking into our reception space was such a joy. Seeing the vision in our heads come to life with Kenzie’s hard work was priceless. I can not thank her enough for her time and energy and truly can’t imagine our weekend without her expertise. Hire One: Twelve, you’ll be so thankful you did!

So talented and easy to work with

Mackenzie was so easy to work with. I wanted a veil with some detail, but not too much since I already had a detailed dress. It was hard to find any veils already available that were like that. Mackenzie showed me some ideas to help me determine what I wanted. Once I decided on the design, Mackenzie hand made it! It came with a nice comb. It was light and airy (just what I wanted), so I didn’t even need to use Bobby pins to keep it in! My half up/half down hairstyle had an easy spot to put the comb into. Mackenzie was on time, professional, communicative, and so friendly! She is talented in many other ways as well, so check out her website for her jewelry, coordinator services, etc.!
