These are the passionate men and women of Mission Discovery!  Since 1991 the Mission Discovery Staff has been ministering to the poor through short-term mission trips, medical missions, and volunteer vacations helping thousands do the same.

Our goal is to provide participants with a unique and meaningful missionary work experience whether it be a voluteer vacation, medical missions trips or even long term mission trips.

Each staff member is committed to making the name of Jesus known through our love and service. Every project coordinator with Mission Discovery raises funds to keep the cost of our mission trips low.

Jimmy Rivera


I am a lover of life and all that God has to offer! My first Mission Discovery trip was as a participant with my church. I helped translate the Vacation Bible School for a week-long trip in Reynosa, Mexico. When I returned home I was convinced that pursuing work with MD full time was for me! That was in 1993. Today I coordinate trips for Mission Discovery, lead our Board of Directors and use my skills in finance and administration to oversee the dollars that flow through our organization each year.
