      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.

      WordPress Website Design Review from Clea Bierman

      Blue Meridian Partners has worked with Constructive as our website design and development partner for more than eight years. During that time, they have played a significant role in shaping our digital presence and helping bring our brand to life online. What I've appreciated most is Constructive's ability to balance creativity with stewardship. They have consistently found thoughtful ways to push our brand forward when innovation was needed, while also respecting and working intelligently within established brand guidelines. Their team understands how to translate complex ideas into engaging digital experiences. Across dozens of projects, I've worked with three different project managers, and each has been highly accountable and genuinely enjoyable to partner with. The relationships have been professional, collaborative, and built on trust. We've also had several occasions where creative projects required significant work on very tight timelines with little notice, and Constructive consistently found a way to deliver. Like any long-term partnership, navigating complex websites and evolving organizational needs requires ongoing communication and attention. What has kept us coming back year after year is Constructive's commitment to partnership, their willingness to solve problems alongside us, and the care they bring to our mission. I am grateful for their contributions to Blue Meridian's growth and would confidently recommend Constructive to organizations looking for a thoughtful, mission-driven digital agency.

      Nonprofits Review from Robert Espinoza

      Constructive built PHIs website back in 2017-2018 and, in many ways, they have been with the organization ever since. Over almost eight years, they've grown alongside PHI rather than simply maintaining a site. PHI is a national nonprofit working at the intersection of research, policy, and workforce interventions on the direct care workforce, and a lot of what we do is complicated. Constructive's remarkable team has had a real knack for turning that complexity into something clear, usable, and genuinely engaging online.Some of the things I'm most proud of from our partnership like our worker story gallery, our national resource center on direct care workers, and our online index came out of that collaboration. These weren't just features; they became core parts of how we tell our story and share our work with advocates, policymakers, and practitioners.What made Constructive stand out was how invested they were in our mission. They were creative and technically excellent, yes but more than that, they showed up as a true partner. We didn't experience them as a vendor so much as an extension of our team. I would absolutely recommend them to any nonprofit or social impact organization looking for a thoughtful, dependable digital partner.

      Nonprofits Review from Diana Denza, MPA

      The Center for Family Representation worked with Constructive on a year-long rebranding process that overhauled our logo, colors, website, and all of our marketing collateral. As a result of this process, we now have a brand that truly represents our organization and the work we do for low-income NYC families. Constructive was highly responsive and professional throughout the process, working with us to ensure that every element of the rebranding felt just right.

      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.

      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!

      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!
