Family doctor initially obliging (4)
I believe the answer is:
kind
'obliging' is the definition.
(I've seen this before)
'family doctor initially' is the wordplay.
'family' becomes 'kin' (synonyms).
'initially' suggests taking the first letters.
The initial letter of 'doctor' is 'd'.
'kin'+'d'='KIND'
(Other definitions for kind that I've seen before include "Friendly; class" , "Stamp" , "style" , "Class, type" , "Generously disposed" .)
