Our Management

We empower ourselves

The Ostfriesische Tee Gesellschaft team is led by Ingo Wiltfang, Annemarie Leniger and Dennis Bender. The management is known for its focus on and interest in its own employees and the stakeholders and their needs.

The managing director of OTG, Annemarie Leninger, is leaning on a counter.

Annemarie Leniger

Managing Director
Responsible for: Marketing, Tea Purchasing, Quality Assurance, Research and Development (Sustainability)

CV: She has been with OTG since 2009. The business administration graduate from East Westphalia-Lippe has always been an enthusiastic tea drinker. Thus, it is somewhat surprising that her first job led her to coffee. Her career started at Tchibo, followed by positions at Mars, Kraft Foods and Nordmilk (today DMK) before she finally joined OTG’s management in 2009.

“Running a 150-year-old company is like steering a tanker: sometimes you have to move more slowly, and at other times more quickly. Regardless, to maintain long-term success, you must continually prove yourself – an exciting challenge.”

Ingo Wiltfang

Managing Director
Responsible for: Sales

CV: He has been with OTG since 1998. This born-and-bred East Frisian from the town of Norden all but grew up around tea. After graduating high school, he joined OTG, completed an apprenticeship, and then earned a degree in business administration. Afterwards, he held a variety of positions within the group. Marketing and sales have always been his primary focus. In 2016, he was named Managing Director.

“Our colleagues’ enthusiasm and passion for the wonderful natural product that is tea coupled with their exceptional professionalism are what distinguish OTG. Based on strong customer and market orientation, we all work together to see ‘more in tea’ every day.”
