Wedi ei eni a'i fagu yn Aberystwyth, cychwynnodd Ceri John ar yrfa eang a oedd yn cynnwys amrywiaeth o swyddi. Ond roedd wastad ganddo’r awydd i addysgu, a diolch i gymhellion Llywodraeth Cymru a'i gariad at Ffrangeg, mae bellach yn athro. Pwnc Ceri yw Ieithoedd Tramor Modern, yn arbenigo mewn Ffrangeg.
Born and brought up in Aberystwyth, Ceri John embarked on a wide-ranging career that took in a variety of jobs. But he always had an urge to teach and thanks to the Welsh Government’s incentives and his love of French, he is now fulfilling his calling. Ceri’s subject is Modern Foreign Languages, specialising in French.
