      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      Had such great care here, all of the nurses were kind and friendly, I completely felt safe and listened to by the anesthesiologist and Dr Roost was excellent at explaining my procedure and clearly passionate and skilled in her field. Clearly no none wants to have a colonoscopy but their staff made it as easy and smooth as possible!

      I was pleased with the services I received in the Waverley surgery center for my much procrastinated colonoscopy. Everyone was friendly, caring and attentive which made me feel comfortable and relaxed. Everything went smoothly, they gave clear instructions for after procedure and called next day to make sureeverything was all right. I highly recommend it.

      Holt Group Inc.'s Review Sourced from Google

      Watson has been a key strategic partner for us on the creative and brand side since the beginning. We've worked with various members across the team and every member of their staff brings excellence and authentic passion to what they do. They have consistently delivered an end product that excites our customers, adding special creative touches along the way so that the results really sing. The way they're able to translate our vision and mission into deliverables across each project has been a weight off our shoulders. Not every creative agency is able to understand the nuances of our industry and we've been so impressed with the time team Watson has taken to really get to know our industry in homebuilding. We've worked with Watson on deliverables such as high level creative direction, but also getting into the nitty gritty of developing content around our warranty program. This was a huge task and they matched us with exactly the right team members to bring it to life who truly cared about getting it right. They're great friends as much as they are our business partners. We highly recommend partnering with Watson Creative.

      S Nash's Review Sourced from Google

      When we engaged Watson to help us rebrand, we knew it was going to be a challenging process. We had a long-standing reputation as a respected law firm in Portland, but we wanted our brand to reflect our unique culture and the innovative approach we bring to our clients. Watson's team was thorough and thoughtful throughout the entire process, from primary research interviews with our team to the final custom, hand-drawn identity system. The end result was a brand that not only represents who we are as a firm but also sets us apart from our competitors. We continue to receive compliments on our branding years later, and we credit Watson for helping us achieve that success.

      Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!

      Meredyth Jones's Review Sourced from Google

      I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.

      Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!
