Profile
Semiotik Design Agency (SDA) is the brainchild of designer and typographer Dimitris Koliadimas, a three time winner of Greece’s highest prize for visual communication.
After 20 years of studio leadership, Dimitris’ standing at the spearhead of Greece’s new guard continues to grow. Since opening in 2014, our agency has assembled a stellar roster of studio and freelance talent — steadily growing our reputation and repertoire by responding to the evolving needs of leading businesses, museums and institutions.
International recognition for our work spans multiple disciplines, and includes awards from D&AD, European Design Awards, Red Dot Design Awards, The Dieline, Pentawards, Type Directors Club and Art Directors Club of Europe.
At SDA, quality is a system, not an aspiration.
Certified under ISO 9001: 2015, we combine creative vision with rigorous processes to deliver design that is precise, consistent, and resilient. For our clients, this means identities that are not only beautiful and culturally intelligent, but also built to perform — empowering brands to inspire trust, adapt to change, and achieve lasting impact.

Transforming brand experience and performance. Informed identity solutions for intrepid businesses.
Great structures need strong foundations. It’s a fundamental concept at the heart of Athens,
and the reason why curiosity and applied craftsmanship are central to everything we do.
We build world-class identity solutions by synthesizing intelligence with well-trained instincts. Every project is the outcome of research, rigor and cultural insight producing work informed by deep understanding of objectives, operating environment and opportunities for growth.
We believe in simple, functional, effective assets that empower our clients and anticipate the future. In times of radical change, identity’s building blocks are necessary constants. Brands need resilient tools and systems to embrace the new, adapt to culture, and pursue lasting greatness.
