Jeff van Steijn


Design is awesome in this case!

Jeff knows what it means to be great listener. By asking the right questions Jeff never fails to get to the bottom of a problem to subsequently tackle it with a large variety of solving designs. Jeff loves every step of the design process and that shows in the results. You can find Jeff acing tennis matches on weekends and acing designs on weekdays.
