BAS GREGOOR
Managing Partner
Bas set up his own company, Gregoor Vastgoed, in 2011 focusing on initiating and mediating investment transactions. Here he gained vast experience in development projects and in the redevelopment of existing real estate. Between 2013 and 2020 he built up the real estate label Cityside Apartments with Rik Klinkhamer.

With his entrepreneurship and extensive network in real estate and finance, Bas knows how to add value to existing properties. His proven track record stems from his pioneering spirit and determination, as well as his pursuit of mutual 'win-win' situations.
