The tale of two brothers

What started in 2002 in a former monastery where our parents lived, is now a flourishing office that is still owned by brothers Merik (1975) and Hendrik (1978) te Grotenhuis. CasaGrande was our nickname on the soccer field; and gave the inspiration for the company name; CasaGrande Selections. Our company now has the name CG Research.

We started CG with the idea that we “could do a better job than the other selection agencies”. Both with a master degree Business Administration, Merik worked as a research consultant at Millward Brown and Hendrik worked there as a student.

The monastery became a busy staffed office with sometimes 50 employees working at the same time. In Hoorn, once again in a characteristic building, we found our current accommodation with more light, more space and closer to Amsterdam.

CG has always developed and extended. In 2009 we got our own research location in Amsterdam, in 2011 we took over RvR from former owner Paula Jap Tjong. Van Hellemond also joined the CG family in 2016 with its beautiful locations in Amsterdam across Central Station and in Amersfoort. All this time we have invested heavily in automation and quality. CG was the first selection agency with ISO 20252. We started conducting online research and even made attempts to start a CG Germany.

And the most important; we always had a lot of good employees who like CG and our parties and we have helped many clients in all those years. The relationships with clients such as Kantar, Mare, Philips and Blauw have been there for more than 15 years!
