      PPC Review from Jim Curry

      At first, a survey was conducted to gather company background, product information, target markets, etc. Next, accounts were established on various Google Business platforms, social media, etc. Then SmartSites created the ads and campaigns, and we were off and running in just a few weeks.

      Web Development Review from Robin Baradarian

      As the owner of ExoClinic Spa, and a physician with more than 30 years of experience building medical practices and businesses, I can say unequivocally that working with Digital Silk has been an extraordinary experience and the best I have had with any web development company to date.From the very beginning, their team demonstrated a rare combination of professionalism, strategic intelligence, and genuine partnership. They took the time to truly understand our brand, our medical standards, and our long-term vision. This was not a transactional engagement; it was a collaborative process grounded in respect, insight, and excellence.Digital Silks communication was consistently clear, proactive, and reliable. Every recommendation was thoughtful and data-driven, and every step of the project was handled with precision and care. They seamlessly balanced sophisticated design with the credibility and trust required in a medical and wellness setting something very few firms manage to do well.The final product exceeded my expectations in every way. The website is elegant, intuitive, fast, and perfectly aligned with the level of care and innovation we deliver at ExoClinic Spa. Their attention to detail, project management, and internal coordination were exceptional.After three decades of working with countless vendors across industries, I can confidently say Digital Silk stands above all others. They are not just a web development company they are a true strategic partner. I trust them completely and recommend them without reservation.

Their creativity, attention to detail, and commitment to getting everything just right truly set them apart.The collaboration felt seamless, communication was always clear, and the final product reflects the high level of expertise and care that went into building it. We are beyond thrilled with the end result and highly recommend their team to anyone looking to develop a professional, high-quality website.An outstanding experience from beginning to end! I also see a long time relationship with this team and company for any other future projects and work.

      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!

      During my tenure at Beaver Creek Resort Company I was tasked with building and launching a guest-facing app for the hundreds of thousands of visitors to Beaver Creek Mountain. I worked very closely with Quartus Technology and their team to meet the budget, the timeline and all the required features for the project. The app launched early! It's been an incredible success and the app has continued into phase 2 and 3 with added functions. I highly recommend Quartus Technology if you are in search of a quality app, strong development team and transparent pricing.

      Mobile App Development Review from Chris Caputo, PMP

      After looking at multiple vendors to build an app to provide information on municipalities we selected Quartus. The scope included the development of the app (including designs) and integration to a service that our development team created. Quartus was successful. They delivered in a timely, cost-efficient manner and were easy to work with. When we decided to have a second app created, we did not look elsewhere and stayed with Quartus. This app involved the development of a calculator to calculate and email title insurance premiums. Like our first app, Quartus had to develop the designs (they were able to leverage a portion of the work from our first app) and integrate to a different service that our development team created. Once again, Quartus delivered. These apps were for Android and iOS. They are a good partner.
