Hayatımıza mucize gibi giren bir hekim! Bu dünyada böyle doktorlar kaldı mı demeyi bıraktım kaldımı böyle insanlar diyorum. Ayağına taş değmesin hocamızın Allah onu ve onun gibi doktorlarımızı başımızdan eksik etmesin onu ve ailesi hep korusun inşallah nasıl ki o bize hızır gibi yetiştiyse rabbimde hocamızın her sıkıntısına en büyük mucizeleri göstersin. Gerek hekimlik bilgi ve tecrübesiyle gerek insanlığıyla çok büyük çok yüce.
