The Team


Arjun Srinivas, Service Designer

Equipped with his multicultural, and multidisciplinary background, Arjun is keen on addressing critical problems in design, business, and society by employing a human-centered approach to deliver meaningful, impactful, and memorable experiences. He has a gusto for those moments, aha or not, when he can think and talk through tough problems with teammates and clients to align on important design decisions.


Becky Scheel, Service Designer

Becky is a visual storyteller and design generalist for human and nonhuman great apes. She focuses on design in complex, dynamic, and unfamiliar environments with emerging technology. She recently returned to Georgia Tech for her master’s degree with a focus on digital naturalism and published her work on orangutans and digital enrichment. She has a passion for wildlife conservation, collecting chairs, live music, and giving a h*ck.


Carol Massa, Service Designer

Carol’s mantra is to facilitate people's lives by using her creative potential to co-create and solve for complex "wicked" problems. Her passion lies in the intersection between arts and science, and she is constantly exploring new ways to build her craft. In her words, service designers play the role of the connector across the organization by integrating initiatives and bringing experiences to life.


Jeff Harris, Service Designer

Jeff’s philosophy on design is that it is fundamentally about making decisions. Confident decisions based on contextual understanding that balances customer desires and needs with business priority and value. Jeff obsesses over identifying and codifying the various facets that enable these choices — customer experience, business strategy, employee goals, and cultural benefit.


Leah Berg, Service Designer

Leah designs as a storyteller, creating lasting and meaningful experiences. Her core values and passion include interpreting and understanding what and how users connect with each other and with services. When she’s not working, Leah enjoys cooking (and eating), traveling, and visiting museums, all of which, provide meaningful insights to her work.


Mariah Mills, Service Designer

Mariah has a background in film production and Master of Industrial Design from Georgia Tech. Working as a service designer brings together her passions for understanding people and their needs, and crafting experiences. Her favorite aspect of service design is the collaborative nature of the discipline, she believes the best ideas come from creative tensions within groups of people with differing viewpoints.


Shreya Dhawan, Service Designer

Shreya believes in working with collaborative, multi-disciplinary teams to develop solutions to complex real-world problems. Her background in Industrial Design helps her understand both the tangible and intangible facets, while being a Service Designer from SCAD has made her expand her knowledge beyond the ordinary, everyday things while still being a humble lover of simplicity.


Stephen Taylor, Head of Design Research

Stephen's unique approaches to design strategy and research—which he calls "precision inspiration"—helps organizations devise new ways of improving people's lives. As Harmonic Design's Head of Design Research, Stephen ensures our practitioners bring both rigor and adaptability to our engagements.
