It is her desire to continue to help others step out of their comfort zones, travel the world, and further Christ’s Kingdom through this. Her favorite quote sums up her passion, “A risk-free life is a victory-free life. It means life-long surrender to the mediocre and that is the worst of all possible defeats” (Jamie Buckingham). Kristi loves to see people take “risks” and see God show Himself strong to them!

Sharon works as a Paraprofessional, teaching and helping elementary children learn, and enjoys influencing their lives.

She has been extremely grateful for a few opportunities to minister in other nations. She has been involved with SGA from its conception. Sharon launched a mobilization ministry in her local church and developed materials in order to encourage others in the pursuit of their purpose, in identifying their giftings, abilities and personality style. She longs to see the fulfillment of the tremendous anointing the church will experience when there is true unity in Jesus Christ.

They know how to give challenging assignments. They know how to give power away. They understand the meaning of servant leadership and they lead in that manner.” It is his desire to see this same quality of leadership developed in a greater way in this nation and across the world and is excited to be a part of it.
