Zijn speciale interesse gaat uit naar de reconstructieve chirurgie. Regelmatig werkt hij hierin samen met de orthopeden. Zo kwam hij in aanraking met Stichting Njokuti.

“Ik was mezelf al een tijdje aan het oriënteren op mogelijkheden om op medische missie naar een ontwikkelingsland te gaan. Al tijdens mijn studie ben ik op meerdere missies geweest naar Ghana, Tanzania en Laos. Het Afrika virus is erg besmettelijk, maar gelukkig niet gevaarlijk!

Met Stichting  Njokuti hoop ik dat er nog vele mooie missies mogen volgen.”
