Bilberrry Reviews & Testimonials
Kelly Johnson eCommerce Specialist at Rapala VMC

eCommerce Development Review from Kelly Johnson
Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.

Web Development Review from Adam Ely, PMP
As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation. The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility.On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams.The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance.Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.
Bilberrry’s work gave our new website improved performance, greater SEO flexibility, and pages that are much easier to build. They delivered everything on time and kept communication proactive throughout. Their strong project management, technical expertise, and responsiveness built real trust during the process.

Design In DC Reviews & Testimonials
Mackenzie Shriner Owner at Distinctive Deck Designs

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!
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.
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!
