Missionaries to Mexico

About US

Rob & Kathryn Harryman | Missionaries to Mexico

We have been passionate about missions for a long time! I (Kathryn) knew I wanted to be a missionary nurse when I was nine. Rob’s call to the ministry came on his first mission trip in 1997 when he was 18 years old. When we married in 2001, we agreed as a couple we would go anywhere in the world that God sent us. That commitment has led us to share Jesus in 12 countries in Mexico, Central/South America and the Caribbean.

Our full-time missionary journey began in September of 2015 when we sold everything and moved to Ensenada, Mexico to train with Youth With A Mission. From the moment we began to work full-time in missions, God had placed in our hearts to pioneer a YWAM base in San Juan del Río, Querétaro, Mexico. That dream came true on October 27, 2017! On that day, our family arrived in Central Mexico and began the work to start a new base with YWAM (Youth With A Mission).

We are now living full-time in San Juan del Rio, and are constantly amazed at the open doors that God is giving us in the Mexican state of Queretaro. We are located in what missiologists (those who study missions) call “The Circle of Silence.” It is called this because the population in this region of central Mexico is less than 2% evangelical Christian. The “Circle of Silence” is the 10-40 window of the Americas. Some nearby towns with a population of 20,000 to 30,000 still have no evangelical church. The city of San Juan del Rio has a population of 300,000 people, and there are about 25 Christian churches. If all the churches were filled, they couldn’t hold more than 3% of the population! This is a place that is ripe for the Gospel, and in desperate need of discipleship, Christian resources, Bibles and churches. Because we are pioneers, everything we do is NEW! That is exciting and daunting, all at the same time. Please continue to pray for us, and visit the website to learn more about the YWAM base at

Romans 10:14-15

"How then shall they call on Him in whom they have not believed? and how shall they believe in Him of whom they have not heard? and how shall they hear without a preacher? And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!"

We are very excited about what God is leading us to do. But, we cannot do this alone! Please pray about partnering with us.

We believe that God is about to do amazing things on this earth, and we are so privileged to be a part of it. Join us as we SHAKE THE NATIONS with His Kingdom!!! God bless you.

Rob, Kathryn, Isaac, Jesse, JonDavid, Emma, and Joey Harryman




Our goal is to have 1,000 people committed to praying for us and our ministry on a daily basis! We are already compiling a list of those praying for us and love watching it grow. If you are interested in being a prayer partner, please send an email to Let us know you are joining our prayer team. We will send you our e-newsletter, in which we will always feature current prayer needs. We will also include praise reports and testimonies of answered prayer. We look forward to witnessing God’s amazing power released through prayer!



We need your help! YWAM missionaries receive 100% of their funding through personal support. What God has called us to do requires us to link arms with others in the Kingdom to accomplish His will!

We are issuing a challenge we call “30 to GO:”

  • If 100 people committed to giving $30.00 monthly, we would be fully funded for our first year!
  • We began to do a little research, and found that:
  • U.S. Americans spend $30.00 or more monthly on common items such as: fast food, carbonated beverages, movie rentals, pet food, pizza & coffee.

Our “30 to Go” challenge is:

  • Would you consider cutting back on one or several of these items and make a monthly commitment to missions?
  • Instead of junk food and entertainment, your monthly pledge can spread the Gospel, encourage the hopeless, minister to the poor, and love the unlovable. Your $30.00 won’t support your local Wal-mart, Sonic, or the entertainment industry; it will SHAKE THE NATIONS!

We also welcome one-time gifts! We want to make giving easy for you, so click the donate button to give via Our online donation page. These donations can be one-time, or you can set up your donations to recur as often as you like.

Finally, you can give by cash/check. Make checks out to RKMissions. Mail them to:

  • RKMissions
  • c/o David Harryman
  • 7233 Heron Dr
  • Joplin, MO 64804

All of these donation methods are tax-deductible. We appreciate you and value your investment in our lives!

One more way to financially sponsor us is to get your church or business involved! We love to visit new places and share our vision with others. A really fun way to get people excited about missions is to do a group effort, like a fund-raiser or a benefit. Please email us at if you think your church or business would like to help!


Missions Trip

Do you have gifts, talents or abilities? We believe everyone does. We also believe that God can use what you are good at to bless others, especially in third-world countries. One of our goals in doing missions full-time is to be a bridge for people like you who have something to give, but need a place to go.

If you have a desire to do medical missions, evangelism, to build and do construction projects, to work with women, children or teens, then we want to help! We will be creating opportunities for people all over the world to join us in ministering to the people of Latin America. Our base in Mexico receives short-term teams, summer volunteers, and also provides missionary training for young people. If you are interested in coming to Mexico to serve or to attend a YWAM school, please email for further information. You can find out more about the base here in San Juan del Rio by going to our website at Come and be a part of what God is doing!

Luke 24:45-47, “…Thus it is written, that the Christ should suffer, and rise again from the dead on the third day; and that repentance and remission of sins should be preached in His name unto all the nations…”
