Professional Summary

Transitioning into the valuations department in April 2014 after having worked as a secretary in the agency department for over 16 years,  I currently hold the position of Associate.  I combine a strong sense of service with a hands on mentality. Currently I coordinate the quarterly appraisals for Altera Vastgoed N.V. and the quarterly appraisals of commercial properties for Syntrus Achmea Vastgoed.



I joined Colliers Amsterdam in October 1998 when it was still called Boer Hartog Hooft as the team assistant for Agency. In addition to regular secretarial duties, I trained many secretaries along the way and helped set up the quality control system. During my time with the company, I have helped implement several software applications. Prior to joining the company, I worked in the Radisson SAS hotel in the city centre of Amsterdam after receiving my Bachelor degree in Hotel Administration from the Hotelschool The Hague.
