OSSO is a nonprofit dedicated to helping orphans throughout the world reach their potential.


Since its founding by Rex Head, MD in 1999, Orphanage Support Services Organization (OSSO) has provided hundreds of volunteer opportunities for individuals, groups, and families to travel and help orphans around the world. OSSO provides one-on-one care to orphans, monetary and material donations to orphanages, and unique travel adventures for volunteers.

Our mission is to do everything possible to help children living in orphanages and similar institutions reach their potential. Currently, our program provides safe, supervised volunteer experiences in orphanages in Ecuador and Thailand.

OSSO is an organization founded on love and service. With us, not only will you get to experience another culture, but you will also get to give love and receive love from the world's most precious blessing: children. 

One volunteer at a time, we can help one child at a time. If you’re looking for a relaxing vacation, OSSO isn't for you. But if you’re looking to do good in the world and have your heart changed for the better, we’re the choice for you. When you volunteer with OSSO, you change a life — often a child's but always your own.


Rex Head, Founder

After adopting two healthy little girls and a young boy with cerebral palsy, my wife and I wanted to do more to help children without parents. We visited and gave assistance in orphanages in several countries, but when visiting girls in an orphanage in Cuenca, Ecuador, I had the feeling that somehow these girls were different. It was like they were my own children. We returned a couple of times as a family and then with a group of volunteers from Ricks College.

In 1999, my wife and I formed a nonprofit organization that began sending groups of volunteers to serve continually, an organization now known as Orphanage Support Services Organization (OSSO).

Since starting OSSO, we've expanded to serve more than a dozen orphanages in Ecuador thanks to the financial support, volunteer support, and consulting support given graciously.

Rodrigo & Lorena Rosero, Orphanage Directors of Los Pequeñitos de OSSO

We started working with OSSO in March 2001. We worked as Project Directors for several years until we became the Directors of Los Pequeñitos de OSSO. As Directors of Los Pequeñitos de OSSO, we serve the children of OSSO by overseeing the employees, finances, and all the needs of the orphanage. We  count on the invaluable help of the Orphanage Coordinator to achieve the organizational goals and objectives. 

We’ve been working at OSSO, we have met over a 1,000 volunteers. We’ve lost count of how many, but we remember them all. The best experiences we’ve had as a family have been during the time we’ve had with OSSO. Half of our marriage has been here, and we’ve learned a lot of things from all the people who have entered our lives. Each person has left a permanent mark in our hearts that has molded our lives. The hard thing about this job though, is having to say goodbye to wonderful people, but at the same time the best part is being able to meet new people full of the spirit of service. As Directors of Los Pequeñitos de OSSO we have learned that it is a blessing to be able to see the world through the eyes of an inocent child. These children are angels and it is a priviledge to have them in our lifes. 

We have two children and a poodle, Cosita. Our oldest daughter, Sammy (23) lives in the USA with her husband, Noah. Our youngest son, Ismael (16) enjoys video games and playing the guitar. We are a close family and love spending time together.

Tessa and Isaac Jamison, Volunteer Directors: Cuenca, Ecuador


Service has always been a huge part of our lives. In fact, we met doing service at BYU-I in a program called Student Support. We became great friends and stayed in contact while Tessa served an LDS mission in Uruguay. Isaac did his internship with OSSO during the summer of 2016. Those two months were unforgettable. He returned home from Ecuador just in time to start the Fall 2016 semester at BYU-I. Tessa, had also recently returned from her mission to Uruguay and would be attending school at BYU-I that Fall. We met up at the beginning of the semester and our friendship quickly grew to something more. 7 months later we were married. While dating, Isaac told and retold Tessa stories of OSSO. We talked about the kids and the adventures he had been on. We decided that if the chance ever came that we would love to be directors for OSSO. Well that opportunity came and we couldn't be more excited! It was on our LDS missions in Mexico City and Uruguay, that we developed a profound love for Latin people and culture. That is one of the reasons we are so excited to be serving with OSSO. Service has a profound affect on both parties involved. If you serve with OSSO you will not only be blessing the lives orphans here in Ecuador but you will come home different, changed for the better.


Kirstin Winters, Volunteer Director: Chiang Mai, Thailand

I grew up in Mesquite, Nevada where the sun always shines. I earned my Bachelors of Human Development and Family Studies from the University of Utah in 2014. I have traveled to Guatemala, Cambodia, and Thailand with various volunteer groups. I love adventure and prefer to travel with a purpose, although I will travel to a beach anytime! 

Having volunteered with multiple organizations, I knew OSSO was special. I was instantly drawn to the special needs orphanage in Cuenca and knew that is where my heart belongs. OSSO has given me the opportunity to do what I am passionate about; care for and love disadvantaged youth. Not only the experience to open my heart to these children, but OSSO has given me the opportunity to experience Ecuador. I have enjoyed the many cities, landmarks, and unheard of characteristics of Ecuador that I am in love with. I encourage all to share this experience with me, to fall in love with Ecuador and the beautiful children OSSO cares for!

Kirstin was in Cuenca for 18 months as the volunteer director there and is now directing the summer program of 2017 in Thailand.
