Jean has been active on the housing market in the Leiden region since the 1990s and in 1999 he was sworn in as a broker/appraiser by the District Court just before the broker's oath and title were abolished. Brokerage is in his blood and he is committed to his clients in the best possible way. Whether it concerns the supervision of a purchase or sale or an appraisal. His motto: Brokerage is not a 9-to-5 job, it is a "way of life"; you are a real estate agent 24/7! Even outside office hours and during the weekends, he is often in charge of his clients. His efforts are highly appreciated which earns him great reviews. Since 2018 he has been working at the DOEN branch in Leiden, together with Paul Rats (the founder of DOEN NVM Makelaars). From his beautiful office on the Kennedylaan in Leiden Zuidwest, he and the enthusiastic Leiden team will be happy to be of service. In his spare time, Jean likes to get behind the controls of a single-engine sports plane as a hobby pilot, but he also enjoys travelling, musicals, a visit to the cinema or an evening out for dinner.

Christa made the switch from business services to real estate ten years ago and would have liked to have done so ten years earlier. The diversity and dynamics of this job, combined with the personal contact makes her feel completely at home in this world. She is spontaneous, cheerful and sees life from the positive perspective. She will run a mile for her clients and will only let go when the best results have been achieved. In addition, she herself has been an Expat for a long time and she knows how to successfully fulfil the needs of this group of people. When she is not at work, she can be found on the water. Sailing is her other passion. Together with her family she is always looking for the most beautiful places in the Netherlands.
