Why volunteering?

Volunteering is based on giving. Your time, your skills, your efforts, your knowledge of a language, these are all put together to help someone who needs it. It is, however, very rare that volunteers do not feel like they have received more than they gave. Volunteering is a mutually rewarding experience. You will end up more independent, wiser and stronger to face situations like public speaking or tough negotiations. Many employers value international volunteer experiences. You are looking at the big picture, acting locally to help globally.

At One, two… Tree! we receive volunteers on a continuous basis. You can either help us in Guatemala or Mexico. If you have more than six months available to work with us, you may look at our long-term opportunities (compensation available). You can also give us a hand from your home town.

Volunteers in Guatemala teach the basics of English to children between 6 and 12 years old. Lessons are taught in public schools of Santiago Atitlán. The average workload is 16 hours per week (you should add some preparation time for each lesson). Accommodation is provided by local families. One, Two…Tree! does not charge any fee, all your costs are paid directly to the host family.

Since February 2019 we are also present in Zinacantan, Chiapas, where we teach English in Melchor Ocampo’s primary school and in Dr. Manuel Gamio’s Centre for Social Integration to more than 800 kids.

Long-term volunteer (Compensation)

Volunteers staying for more than 6 months in Guatemala or Mexico may apply for the Volunteer Coordinator position, which includes free accommodation and food. Staying 6 months does not automatically grant free accommodation, there is a screening and selection process and only a few positions are available.

You will coordinate the local project together with Pedro, the Director of One, two…tree! At the moment, only two coordinator positions are available, this means that only a limited number of applications for these positions can be accepted. However, regular volunteering is very affordable and we give priority to longer stays. If you are interested, please contact us to check out the open opportunities.
