DESIGN B3

On behalf of the HUK-COBURG branch office in Cologne, I’d like to highlight the consistently excellent and fast work from Design B3 in Leverkusen. A big thank-you to Gunna Holz, who turns our ideas and suggestions into a professional, appealing layout that always matches our style—and leads to a lot of positive feedback from our customers.

For many years, the Leverkusen Child Protection Association has been working with the advertising agency DESIGN B3. With every project we’ve completed together, the conclusion is always the same: it doesn’t get any better. Gunna Holz stands out for his creativity, friendliness, speed, and flexibility. He picks up on our own ideas and expectations thoughtfully and refines them with his professional expertise and technical capabilities. In the end, all the deliverables are implemented and designed to the very highest standard. Thank you—and here’s to many more good creative times together.

Everyone can benefit from his experience. For us, it’s clear: we’d go back to him anytime. Thank you for the great support!
