General Director
Julie Chamberlain

Hi, my name is Julie. I am a single missionary with theUnited World Mission(UWM). It has been my privilege to be associated with the Spanish Language Institute since 1989, when I was a student here, and later from 1993 to the present, as General Director.

The most gratifying part of my work is to hear the testimonies of scores of new students each year who have responded to God's call to serve him in the Spanish-speaking world, and then see them graduate months later with the linguistic tools, cultural experiences and spiritual lessons that will help them fulfill their calling.

Besides my ministry at the Institute, I coordinate a work in the women's prison sponsored by my local church. For recreation, I like to swim, take walks and read. During trimester breaks, I slip home to visit my parents and three sisters in Michigan, where I sometimes get to play golf; and Colorado, where I enjoy skiing.


Financial Administrator
Luis Diego Bolaños

I am a systems engineer with a master’s degree in Business Administration (emphasis in Marketing), Industrial Engineering and Business Innovation. I also have a doctorate in Christian Leadership. All of these are related to and useful for my position here at the Institute.

I joined the Institute family in 2017. Being able to work at the Institute means to me that the Lord’s plans and hopes for my life are being fulfilled, along with my own personal and family goals. In all my thirty years of work history I’ve served at secular institutions and now, side-by-side with my ministry as Pastor at Comunidad Cristiana La Verdad, for the first time I am able to dedicate all of my time to the Lord.

In my free time I enjoy studying the Word and writing articles for the Facebook page of “Comunidad Cristiana La Verdad”, which has a community of almost 50 thousand people across 50 countries. I am also an amateur runner. I run two races per month, for which I train every day in the early morning hours, during which time I also speak with God. I also enjoy riding my bike in the mountains during the weekends; and playing with my dog Chispa, who was rescued off the streets a few years ago.

My wife Rosi has always given me her full support in everything that I do, whether work related, ministerial, or personal. She is an interior designer who is currently the quality manager at a store that sells formal dresses and gowns. My son, David, is a civil engineer and pilot, and currently single. Cristina, one of my daughters, is a social worker at a non-governmental agency of the UN that helps refugees. My youngest daughter, Daniela, is a publicity designer. She works in her own design studio and part-time in a publicity agency; she is also a youth leader at her church. My mother still treats me as though I were her baby, and my father is in the presence of the Lord.


Guis Leitón

Hi! I'm Guis (sounds like "G's").

I have been at the Institute for many years and have had the priviledge of working in all of the departments. My home church is Comunidad Cristiana El Bosque.

In my spare time, I like to watch sports and work on cross-stitch projects.

My favorite team in Costa Rica is Saprissa, and in the US it's the Broncos.


Gil Obando

I studied Accounting, Finance, and Law in College. I joined the Institute family in February of 2014. The Institute is an instrument to evangelize and glorify the Lord. It is a great blessing to be part of this missionary work. Everything that I do, all my administrative, financial and legal experience, I have placed in the hands of the Lord, so that it may be used as a service to others.

I enjoy spending time with my wife, cooking, running, reading, and playing guitar. I also enjoy hiking up the tallest mountain in Costa Rica, the Chirripó. I am originally from the southwestern coastal area of the country and come from a large family of eight brothers and sisters.

For most people, learning a foreign language is demanding. Learning Spanish when you are in your late 50s is an even greater challenge, one that is both rewarding and at times overwhelming. The Institute offers an incredibly supportive Christian environment in which to learn this beautiful and new language. The teachers and the staff are not only excellent instructors, they have become our friends. They want us to succeed and do everything they can to help us learn this language – and they’re good at it. They’ve been successfully teaching students for over 65 years and have a heart for missionaries. They laugh with us, cry with us, pray for and with us, and in the midst of all this, even at our age … we learn Spanish! In a short time, lifetime friendships are forged with the other students as we all prepare to spread out around the globe in Spanish speaking countries. We arrived speaking little or no Spanish and we have come leaps and bounds in our learning. Thank you the Institute for your wonderful programs! The school was recommended to us and we now understand why. Even though this is one of the hardest things we’ve ever done, we highly recommend the Institute to anyone wanting to learn Spanish!
