Thomaida Hudanish, Director of Missions and Evangelism for the Greek Orthodox Metropolis of San Francisco, explores keychain leadership - a concept developed in Growing Young by Kara Powell, et al. 

• Key-less leaders may be young or inexperienced who strive to prove their worth in possessing keys in order to gain authority or access.
• Key-hoarding leaders run the show and refuse to give others access and share responsibility.
• Key-loaning leaders reluctantly or temporarily loan keys to others and then quickly take them back.
• Keychain leaders are aware of the keys they hold and intentionally open doors for some while training and entrusting others who are ready for their own "set of keys." 

Thomaida suggests that keychain leadership works not only in developing youth, but in engaging new church members through missions and evangelism.
