Many organ builders work at Flentrop all their lives.
Apart from these very experienced people we also have some young talents with us.
We invest in people in order to pass on our expertise, experience and skills and we feel it is important to contribute in that way to the rich organ culture in the Netherlands.
As jurisdiction is based on the law, but justice is only found in the courts when judgement is pronounced, and, similarly, music may be written down but only comes to life when it is performed, so it is in organ building.
Theories, dimensions, scaling and detailed drawings are of the greatest importance but true insight into organ building is found only in the workshops where organs are built.
That is of course why we like to invite potential clients to come and visit our workshops.
We want to make sure that the building and restoration of organs keeps being carried out at top level. We are very pleased that an increasing number of our employees are also active as musicians.
The following people are all employees of Flentrop Orgelbouw:
Assembler; with us since 1968.
Ko has worked as an assembler on the most diverse types of organs. He worked in places like Jakarta, Tokyo and many places in the USA.
If it moves, you need Ko! He is the specialist on the action.

Cavaillé-Coll organ in the Philharmonie in Haarlem.
Ko worked, to mention two instances, on the restoration of the antique case of the Strümphler cabinet of the Bachvereniging in Naarden, and on the restoration of the choir organ in Alkmaar.
From 1976 to 1986 he built a new organ (II/P/15) with Frits Elshout and two members of the congregation of the Gereformeerde Gemeente in Zaandam. He regularly plays this organ during the services.
Ko retired in 2012, but is regularly available and active for instruction colleagues etc.

He worked as a voicer on many projects, including both organs in the Laurenskerk in Alkmaar, the Sint Jan in Den Bosch, the Westerkerk in Amsterdam, and on the re-voicing of the Müller organ in the St. Bavo in Haarlem.
Frits's thorough knowledge of the construction of organ pipes, especially of tongues, is of invaluable help in his work as a voicer.
In 1998 he was became Deputy Director, with all
voicing activities under his supervision. From the death of Cees van

Tuner/Voicer, working since 2015.
Klaas studied at the Conservatory of Amsterdam (organ, church music
and choral conducting) and worked as a conductor. Since 2010 he has

As the university Organ Scholar, he played the organ at academic ceremonies and services and accompanied the university Chapel Choir during their busy schedule of evensongs, concerts and radio-broadcasts.
In 2009 he was awarded the Flentrop Scholarship by the Eric Thompson
Trust which involved spending two weeks in the Flentrop workshops
learning the basics of organ-building whilst also receiving lessons
from esteemed Dutch organists. This experience, and especially the
confrontation with mechanical-action organs, inspired Ross to move to
the Netherlands for further studies with Pieter van Dijk at the
Conservatorium van Amsterdam. He graduated with a Masters degree in
organ in 2014. Ross is organist of the Mozes en Aäronkerk in
Amsterdam and is rehearsal-pianist for the Amsterdam oratorio choir COV
From day one working at Flentrop, Ross was immediately "thrown in at the deep-end" as he was commisioned to design (with guidance from colleagues) a new, independent pedal-division for the Protestant Church of Warmond. In a short space of time, he has already been part of two extraordinary projects: the restoration of the 1781 Hinsz organ in the Martinikerk of Bolsward, and the restoration of the 1611 Hummel/Nitrowski organ - the oldest organ of Poland. Under the guidance of experienced co-workers Rutger and Paul, Ross helped with the disassembly of these two organs and will spend the next period helping with the restoration of the various parts and the documentation of the historical pipework.
