The faces behind

The rainbowtrekkers management team

Joel Mertens
Founder and CEO

Joel MertensMy passion is to create living and learning environments for children. When searching for suitable daycare solutions for my daughter in 2006, I was not convinced by what I found in Cologne. Since then I have been developing my own daycare centers.

I grew up in Germany and lived abroad for several years. In my life I am surrounded by people with diverse ethnic and religious heritage, therefore I want rainbowtrekkers kindergartens to be shaped by multilingualism and an international scope as diversity and respect for others are values we stand for.

Currently our team consists of over 40 employees who share the same ideas. I’m convinced that education only works through relationships. Children need people who they can trust and whom with they can build long-term relationships in their everyday lives. This is why I am striving to create jobs where educators feel comfortable. That includes unconditional respect for the daily educational fieldwork, as well as provide creative freedom to the teams and leaders to develop themselves.  Additionally, I support my colleagues in advancing their further education and training.

I have studied in Germany and abroad and hold a MA degree in Humanities from the Hebrew University of Jerusalem. My personal professional background builds up from international work experience focusing on social economy, quality management and kindergarten administration.

Sandra Leonie Schaffrinna
Head of Human Ressources

LeoInspired by the open attitude of rainbowtrekkers towards diversity and individuality, I proudly joined this rainbowtrekkers team in January 2019. I come to rainbowtrekkers with a B.A. in Social Work and an M.S. in Business Psychology and many years’ experience in human resources.  Here are rainbowtrekkers in addition to providing a strong concept, great materials and wonderful facilities, it is also necessary to provide strong qualified pedagogical professionals.

My challenge as the HR-Leader during the recruiting process is, to find a good fit between applicant and rainbowtrekkers, for both sides. I will endeavour to shape good working conditions by being active, aware, and positive. I look forward to offering development opportunities for our teams and its individuals. Our goal here at rainbowtrekkers is not only to attract parents and children, but also motivated and involved team members. Through these strategies I aim to keep personnel fluctuation low, therefore creating opportunity for children to build reliable relationships to our pedagogical professionals.

Sannia Ott
Educational Coordinator

Sannia OttAt rainbowtrekkers, I safeguard the implementation of management guidelines in the everyday work of the kindergartens and raise the management’s awareness for the daily operational needs of the different kindergartens and their teams.

My aim is to bring our different centers closer together and to develop a common pedagogical framework with the different teams. I also help out in the groups of our three kindergartens regularly where I enjoy my time with the children very much.

I have previously worked as an educational specialist in a mother-child facility. I hold a BA degree in Social Work and have completed a training program as a coach specialized in individual psychology.
