      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!

      StormwaterONE .com's Review Sourced from Google

      Do not use this company for Google Ad management. The first 6 weeks out our ad spend spiked to ~$25,000. The issue was resolved and we were on the right track for a time, however, they completely disengaged with us over a year ago and continue to bill us as if they are managing our ads. We have had audits performed by other PPC consultants and they have verified that our ads haven't been touched in over a year. I have made several attempts to contact the owner to have this issue politely resolved. I now have been informed that the company has been sold. The account manager has continued to ghost us. Please contact me. UPDATE: Jeff I can't believe you auto charged me once again. After posting this review you contacted me and it was perfectly clear by that conversation that we are no longer using your service. You crossed an ethical line when you implied that discontinuing your service meant our ads would be turned off. The ads are riddled with errors form broken bid strategies to the use of broad match keywords. These are just two examples of the issues I continued to bring up that needed to be addressed. Your company's Ron Popeal - "set it and forget it" billing practices and service approach needs to be addressed. This is the exact reason why your company was asked to leave our Vistage preferred providers group. Your company is untrustworthy and incompetent.

      Image Works is an exceptional website management and advertising agency that stands out among competitors I have worked with in the field. They've acted as the diligent custodian of my social media presence, meticulously managing every aspect to ensure optimal visibility and engagement.Their expert team also implemented an advanced tracking system for my Managed IT services company's website. This has provided me with valuable insights that have helped shape our online strategy and build a robust digital presence. Over the years, I've observed a notable surge in the volume of phone calls I receive, testament to the effectiveness of our web optimization strategies facilitated by Image Works.In addition to their proficiency in technical areas, Image Works exhibits an impressive flexibility in the services they provide. They've been nimble and proactive, adapting their strategies to the evolving digital trends and the specific needs of my business. This kind of personalized approach is not something you come across every day, and it truly sets them apart.But where they truly shine is in content creation. They've taken up the reins of our technology blog, consistently producing high-quality, engaging content that accurately reflects the services we provide as a company. The content is not just informative, but also resonates well with our target audience, helping to build a strong connection with our potential customers.I wholeheartedly recommend Image Works to anyone seeking a web development or advertising company. Their comprehensive services, their dedicated team, and their commitment to delivering results are second to none. Trust them with your digital needs, and they'll ensure your brand's voice resonates loud and clear in the vast digital sphere.
