Design In DC Reviews & Testimonials
Web Design Review from Mackenzie Shriner
I contracted design in DC to build me a custom website. they were accommodating of my budget, very responsive, and gave good insight on layout, content and design. the process was very straightforward and the final product is great!
Web Design Review from Jo Maney
DDC has been an excellent partner since we engaged with them in 2023. The DDC team worked with us to completely redesign our website and work to provide ongoing digital marketing services. The DDC team has been responsive, proactive, and thorough with their work. They are also very transparent about how they operate and how much time special projects will require. We have referred DDC to several clients and partners thanks to their outstanding process and product. DDC is a very professional, creative, and well-organized team.
Web Design Review from Sapna Doshi, Ph.D.
My experience working with Design in DC was incredible. Everyone was friendly, approachable, and seemed to genuinely care about helping create the best possible website for my business. They were also invested in making sure the process was one in which I enjoyed and felt taken care of. The regular meetings made me feel like I was a priority and that progress was continually being made. I so appreciated the attention to detail in regards to the user experience. The collaboration in understanding my wishes and desires for the website and user experience was met with patience and paying attention to detail on my behalf. Not only were they taking my suggestions but offering their own to help me maximize the potential of my website. The design and functionality is more than what I could have imagined. I know, undoubtedly, that the work that Design in DC did for me will help my business grow. After wasting money in years past on website designers, I was worried I'd be doing hte same here. I was wrong. I don't think I'll ever need to search for another website designer group again. I would recommend this group to anyone I know. Thank you, Design in DC! It was an absolute pleasure working with all of you!
