Leadership

At Orchestra, Derris works closely with founders and executive teams navigating expansion, reinvention and increased scrutiny. He helps them define what is essential to their identity and build from that center as they scale. That approach shapes how the firm builds enduring partnerships and helps organizations create impact that lasts.

Derris began his career in political communications before moving into senior agency leadership. In 2013, he founded Derris, a consultancy built on the conviction that brand and communications belong at the center of business strategy. The firm became a trusted advisor to generation-defining companies including Warby Parker, Glossier, SKIMS, Hims and Starface. Working directly with founders, he helped shape identity early and create narrative architectures designed to support long-term expansion. The firm earned recognition from PRWeek and PRovoke Media for creative and strategic excellence.

In 2022, Derris integrated his consultancy into Orchestra, extending that brand-led philosophy into a broader enterprise built for modern organizations. The integration expanded his scope from shaping individual companies to influencing how a full-service advisory and marketing agency competes in a converging landscape.

Beyond Orchestra, Derris remains closely connected to the entrepreneurial ecosystem. He is Founder and Managing Member of Amity Supply, a venture firm investing in early-stage consumer companies, and has invested in and advised more than 120 businesses. He serves as Advisor-in-Residence at Columbia University’s Entrepreneurship Program and sits on the Board of Visitors at the University of Wisconsin-Madison. 

Derris has been named to PRWeek’s “40 Under 40” in recognition of his leadership in brand communications. He holds a B.A. from the University of Wisconsin–Madison.

Rosen brings more than two decades of experience providing first-chair counsel to CEOs and leaders across the intersection of communications, public policy and culture. In 2005, he co-founded BerlinRosen and built it into one of the largest independent communications firms in the United States. During his tenure, the firm earned more than 50 industry honors, including PRWeek’s Outstanding Large Agency of the Year and significant recognitions from Observer, Forbes and PRNews.

The decision to launch Orchestra marked a structural evolution. Rosen saw that leaders were operating in an environment where reputation, regulation, culture and market performance were increasingly intertwined. Meeting that reality required more than adding services; it required building a unified institution from the ground up. Orchestra was designed to reflect that shift, bringing sustained clarity and discipline to moments that shape organizations for years to come.

In a world where clients are inundated with tactics and audiences are overwhelmed with too much information, Orchestra is an integrated advisory that leads by building trust with clients to say the hard thing, diagnose the real problem and define what matters most to move the needle.   

Rosen has been recognized by PRWeek and Crain’s New York Business as a “40 Under 40” leader. He serves on the boards of the Brooklyn Museum, the PRCouncil and the AdCouncil.

He holds a J.D. from New York University School of Law and a B.A. from Rutgers University.
