Translations of "Keeper" and "Healer"

Hello! I'd like to know the Sindarin for "Keeper" and "Healer". The verb to keep is 'hab-' but the only word I can find for heal is healing: 'athae'. Could someone help me? Thanks a lot!

The suffixes to form agent nouns ("person that does X") are -or and -ron:

For keeper, at least in its usual sense I'd use gartha- "to defend, keep" and form garthor/garthron from it. For "healer" one could go for nesta- -> nestor/nethron or use athae "healing" in as atheron (the verb that corresponds to athae means "to ease, assist" rather than "to heal", but -ron apparently can attach to nouns as well)

Very helpful, thank you so much!
