It is with broken hearts that we announce the sudden passing of our beloved Derek. He has gone to be with His Lord and Saviour, too soon, at the young age of 36.

Derek leaves an aching hole in the family and friends he leaves behind.

He leaves behind his best friend, the love of his life, Hali, and his daughter Lylah, his heartbroken parents Dave and Tricia Cook, siblings Brian and Jess Cook, Janine Cook, Jeliesa and Mark Tiersma, nephews Cohen and Luke Tiersma.

Loved by his Pake and Beppe, Peter and Maaike Brouwer, and his Opa and Oma, Dick and Cathy Kok.
