mongoose-schema-extend

This is what you want. The concept of "inheritance" and discriminatory field. Give it a shot. I used it and works wonders. Basically you have 3 types of users: basic, advanced and expert. Each is based on your core/base model and then you extend with extra properties you need, defining one inheritance per role.

This gives you a lot of advantages, mainly: mongoose will populate the appropriate model and kick any validation you have in the derived models, etc.
