About UX

As an emerging practice, UX leverages strategic partnerships with larger firms in order to adapt and maximize our team’s value to a diverse client list which has included Biogen, Grubhub, Beam Therapeutics, Massachusetts Medical Society, the City of Boston, the City of Malden, and Breakthrough Properties. We have cultivated the trust of these organizations and our partners and work hard to maintain it by delivering consistent, creative design solutions on time and on budget.


Founded by Susi Sanchez in 2019, the user experience is the firm’s namesake and core value. Our design approach is not grounded in the personal expression of the designers, but rather in the contribution the design makes to the well-being and whole experience of everyone who inhabits and uses the space. Throughout the design process, we ask ourselves: How does this space feel? Did we make it better?


We are a certified M/ WBE business, and we welcome the opportunity to bring our perspective to the design industry. M/WBE certification has allowed us to not only grow our practice but has provided our firm access to mentorship from our more established partners. We hope to continue to develop these important partnerships and make meaningful contributions to the built environment.
