Content Marketing Manager

Tanja Hartmann

As a content marketing manager at ZEP, I combine creative ideas with strategic thinking to develop brand-relevant content. I find inspiration when traveling, in profound conversations and in small everyday moments. With a passion for storytelling and a clear focus on target groups, I start every day with a good cup of coffee and a new challenge.

5 facts about me:

🏝️ Travel Junkie: Road Trip, Mountains or Beach - The World Is My Home

👪 Family Guy: Mother of 2 Children, Wife & Northern Lights

☕️ Coffee Lover: My Start to a Productive Day

🚜 Country Egg: Grew up in a village of 300 people.

📝 Dr. Blog: That's what my husband calls me when I'm immersed in work.
