“I cannot say enough wonderful things about Aspen & Ivy! From the very beginning, they went above and beyond to make my wedding dreams come true. Their organization, creativity, and calming presence made what could have been a stressful experience completely seamless and enjoyable… The day of the wedding was absolutely perfect and ran smoothly from start to finish.”
 — Hadley F.

“Aspen & Ivy was amazing to work with. We spent a year planning our wedding and they  made every step easy and seamless. I didn’t have a real vision of what I wanted when we first met. I knew only a few things: I wanted mountains, I wanted bold colors, lots of flowers, and a good photographer. They took these very minimal notes and crafted something wonderful. I can be an indecisive person, and at every turn they narrowed their  options to 3 and made it that much easier to choose. And their choices were always phenomenal. They understand what their clients want and if there’s any doubt, they  communicate clearly. At the start of the year, I lost my grandmother and they handled everything afterward in stride. They were empathetic and kind, and I’m so grateful. My wedding was a dream, and they made it into a reality. They were was the first choice I made upon starting down that stressful, overwhelming road of wedding planning and I’m so thankful we went with them.”
— Caren S.

“I am genuinely delighted to write this review, as I cannot recommend the team at Aspen & Ivy highly enough. We hosted an intimate microwedding weekend, fewer than twenty guests, at Magee Homestead in Saratoga, Wyoming, and the experience was nothing short of extraordinary. Perhaps the most telling endorsement came from my mother, who was initially skeptical about hiring a coordinator (a requirement of the venue). Over the course of the weekend, I heard her say no fewer than three times, “Aspen & Ivy was the best money spent,” a sentiment that carries particular weight when one considers how quickly wedding expenses accumulate. From the earliest stages of planning, there was a steady and intuitive presence. They offered guidance when I needed help making decisions, gave me space to obsess over the minutiae, and gently steered the process with quiet confidence and deep expertise. Their ability to navigate complex family dynamics, advocate for my vision, and identify thoughtful compromises speaks to a level of professionalism that is both rare and invaluable. I am profoundly grateful for their support, and I know our venue and vendors felt the same. On the day of the wedding, I had no idea what was happening behind the scenes, but I never once doubted that everything would unfold flawlessly. That sense of calm and trust, especially for someone who leans toward control-freak tendencies, was a gift in itself. Despite the many moving parts, locations, and logistical intricacies, the weekend ran seamlessly. I truly believe it would not have been possible without Aspen & Ivy’s involvement. Hiring Aspen & Ivy will be the single greatest favor you do for yourself in the wedding planning process. Their work is not only exceptional, it’s indispensable.”

“We had an incredible winter destination wedding in Steamboat Springs, and we couldn’t have done it without our fantastic wedding planners, Aspen & Ivy! Planning a wedding from afar could have been stressful, but they made everything seamless. One of the things that stood out was how organized they were. They used an amazing planning software that kept all our to-do lists, financial planning, contacts, and schedules in one place. This made it so easy to stay on top of everything and made us feel confident that no detail would be overlooked. Aspen & Ivy were pros when it came to handling all the logistics of a winter wedding in a remote location. From coordinating with vendors to managing logistics in snow, they ensured everything went smoothly. We didn’t have to worry about the typical challenges that come with a destination wedding, because they had it all under control. Their communication was always clear and prompt, and they made sure we stuck to our budget while keeping everything on track. If you’re planning a wedding in Colorado or any destination, we highly recommend Aspen & Ivy for their ability to manage the logistics and make the process easy and stress-free.”
 — Anna D.

“We worked with Aspen & Ivy to plan a winter destination ski wedding, and we absolutely could not have done it without them. They were excellent when it came to all of the tasks that you hire a wedding planner for: coordinating with the venue, excellent vendor recommendations, managing the budget, creating the design for the reception, etc. We felt very comfortable knowing that they were always on top of every timeline and were always very communicative with us. They also were incredibly flexible and accommodated to meet around our work schedules. But, the best part of working with Aspen & Ivy was that they were always willing to go above and beyond to help us make our vision a reality. We knew that we wanted to have a casual ski ceremony, but we could not find a spot to reserve. The next time that they were in town a year before our wedding date, Aspen & Ivy scouted out an area and filmed it to show us how it could work. We always felt like they had us in mind and how to make our day better. We were able to fully enjoy our wedding weekend without any stress because we knew that the Aspen & Ivy team had everything under control and made the logistics of the day seamless and we knew they would easily handle anything that came up. Overall we had a great experience working with Aspen & Ivy and couldn’t recommend them highly enough.”
