The small organ on the east side of the church was built in 1963 by D.A. Flentrop from Zaandam.
It was tuned and slightly altered  in 2001.
In that year it was named after the minister Ds.
H.A Visser who was the man begging for money to buy the organ in 1963.
He succeeded.
The organ has 12 stops over 2 manuals and pedal.
Since 1963 the organ case was in not painted but plain oak wood.
After the renovation it was painted in a light green color.
In 2017 the organ was cleaned by Flentrop Zaandam.
During the church interior restoration it was packed against the dust.
