Tammy Hayson

Program Coordinator

In Dec. 2007 I asked Garry and Terry how I can help with the Christmas boxes. After going to Mexico to deliver them and seeing the smiles and joy on the faces of the children, I knew God was nudging my heart to do more with Harvest Hands. So out of obedience to the Lord, I started volunteering to help how ever I could. I love serving with HHM because I love seeing impoverished children get cared for, and I wanted to do what ever I could to help.  My favorite Bible verse is Phil. 1:6 (NKJV) - being confident of this very thing that He who has begun a good work in you will complete it until the day of Jesus Christ.

Tammy has worked with HHM since 2008 and has the heart of a servant...she oversees shopping for Resplandor De Vida's needs monthly and the student program. She is our El Paso respresentative and program coordinator for school supplies and Christmas boxes and helps in many other ways.

Celia Álvarez

Mexico Student Program Coordinator

Harvest Hands Ministries (HHM) has changed my life. I was a sponsored student from the beginning of Secondary School in 2002, until the end of my Bachelor’s Degree in Public Accounting and Finance in 2014. For me, it was a great blessing because it was an answer to my prayers. When I graduated from sixth grade of Primary School, I knew that I could not continue studying, for lack of resources. My parents had already talked with my brother and me to tell us that although they would like for us to continue studying, it would not be possible. And as a wonderful response to our prayers, HHM came into our lives. Thanks to God and HHM, I was able to finish a career at the University.


Through all of these years with HHM, I have seen how this work of God has touched the lives of several families like mine. That is why I have wanted to collaborate in this great work as well. Since January of 2009, I have helped the ministry as best as I can as coordinator of the sponsored students outside of Resplandor De Vida. I help with things like: attention to the students, filling in school forms, enrollments, payments, purchases, collection of receipts and report cards, delivery of Christmas gifts, making databases in Excel, etc. It brings me great satisfaction to help in anything I can for the ministry because in that way, I am thanking God for having placed people with great hearts in my life, and I feel happy that I can participate in helping other people.

Brian Hill

Work Team Construction Supervisor

I have always had children at the center of my heart. Jesus put them there. I have worked alongside Harvest Hands more than 15 years welcoming work teams and assisting them in construction and culture day. I do this because Harvest Hands meets children’s needs more completely and on a deeper spiritual level than most ministries, with integrity and compassion.

He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.

I will say of the Lord, He is my refuge and my fortress: my God; in him will I trust.

Psalm 91: 1-2

Brian is on Harvest Hands Ministries' board of directors.
