ir. Henk Olie (1956 – 2024)
Met diepe droefheid delen wij het nieuws dat onze gewaardeerde collega en vriend, Henk Olie, afgelopen week is overleden. Sinds 1980 was Henk een onmisbare kracht bij r+k en bij de ontwikkeling de Ple4Win software.
Wij zullen ons Henk herinneren om zijn bevlogenheid, zijn kenmerkende humor en zijn toewijding aan ons bedrijf. Henk was een stabiele kracht binnen ons team en een hartelijke collega. Zijn creativiteit, zijn kennis van softwareontwikkeling, in het bijzonder van onze Ple4Win software, en de professionele wijze waarop hij met onze klanten omging maakten hem geliefd en gewaardeerd.
We zijn dankbaar voor de jarenlange samenwerking, collegialiteit en vriendschap. Henks bijdrage heeft een onuitwisbare impact op ons bedrijf gehad en zijn werk zal blijven voortleven. Het is op het fundament dat hij heeft helpen leggen dat wij zullen blijven bouwen aan de toekomst.
Onze gedachten gaan uit naar zijn familie en vrienden in deze moeilijke tijd. Henk zal gemist worden.
