“Kimmoy consistently demonstrates a strong ability to multitask. On a daily basis, she manages multiple competing priorities. She has excellent collaboration skills, which allows her to tap into others for assistance as needed.”Tangie David, Product Director at MSRB
"This was a pretty great read--you went over and above in your research efforts, and it's very much appreciated...I think your changes definitely organized these points in a more logical order, and the takeaway you added from the new content is perfect."Bridget Healy, Editor at Influence & Co.
"Smart, fast and a joy to work with, Kimmoy excels as a content strategist & technical writer. Kimmoy and I worked together for the past year where I was the Product Manager and she was the content strategist for my product area. Kimmoy has a strong end-user focus, and she constantly made sure our product and documentation communicated the right message for the given context. I was impressed by her ability to handle multiple simultaneous product launches and easily move between the tiniest detail and the big picture message. Kimmoy would be a great asset on any team."Sylvanus Bent III, Product Manager at Google
"I want to give a special shout out to Kimmoy Matthews. She walked into a SUPER COMPLEX and DISORGANIZED space, bringing leadership and a design perspective to the process. I heard from several individuals that the way she showed up was powerful and effective. She also set the bar very high with her excellent style guide, about which I’ve heard so many compliments. I hope you did, too, Kimmoy. So join me in congratulating Kimmoy on a very successful Membership launch.”Megan Gaffey, Sr. Manager of Experience Design at Best Buy
We were collaborating with Kimmoy and Fernanda while they were traveling in Slovenia and preparing the content for social media #ifeelsLOVEnia publishing that were promoting our tourist landmarks. We have found the collaboration a success. Kimmoy and Fernanda managed to exceed our expectations. They produced high-quality content, with an enthusiastic, unstoppable can-do attitude. We can highly recommend them and wouldn't hesitate to hire them again in case we run a similar campaign."Aleksandra J. Topolovec, Slovenia Tourist Board
