Our Story
Common Ground International was founded in the fall of 2001 by Rory and Leslie Foster, two educators who were teaching Spanish at a college preparatory school in Colorado. They recognized a growing need for practical, purpose-driven Spanish instruction that prepared people not just to learn a language, but to use it confidently in real bilingual settings.
What began as a small initiative rooted in classroom teaching has since evolved into a national provider of Spanish training, immersion programs, and professional language services. Over the years, our programs have expanded, our team has grown, and our mission has deepened — but our commitment to accessible, impactful language learning has remained constant.

Meet the Common Ground Team
Leslie Foster
CEO
When I was 16 years old, we hosted an exchange student from Spain. At the time I was annoyed because she would smoke out my bedroom window. But my perspective quickly changed when I had a chance to live with her family in Spain for the summer. This experience opened my eyes and ignited my love and passion for learning Spanish, experiencing and learning about other cultures and seeing different lifestyles. This passion continued into college where I had the opportunity to live and study abroad in Costa Rica. The day I left Costa Rica, I wrote in my journal “I have got to figure out a way to make Costa Rica a part of the rest of my life and share my passion for language and cultures with others” This experience led to the birth of our Spanish Immersion Programs.
These days, I spend a lot of time involved in the planning and coordinating of our Spanish immersion programs and creating new Spanish learning opportunities for the Common Ground Community. I’m honored to lead our team of incredible teachers and Spanish Immersion leaders as well as continue to spread the mission of Common Ground International: Impacting communities through Language whether that is in the United States or abroad.
Rory Foster
COO
Rory began studying Spanish in middle school and always enjoyed learning the language. He took a brief pause in high school when his only upper level Spanish options were with the teacher that he didn’t enjoy. So he started back over with Spanish in undergraduate. He met Leslie in a masters program in Colorado and the Common Ground story began to unfold from there.
Today, Rory loves leading the Common Ground team of linguists and support staff and helping Common Ground’s community members achieve their Spanish goals. He enjoys encouraging learners to speak more, which in turn impacts communities across the country.
Alexandra’s passion for teaching began when she moved to Nicaragua in 2010 to undertake an internship at a non-profit Spanish school. Following several years working in the non-profit sector, she opened a Spanish language tutoring program in a coastal Nicaraguan town. In 2018, Alexandra branched out to online tutoring and currently teaches Spanish and English online, as well as works as a freelance translator, interpreter, and copywriter. Additionally, she has contributed content to Spanish language learning platforms, and written YouTube video scripts, e-books, blogs, and curriculums, all with a focus on learning Spanish.
Alexandra loves teaching because she gets to interact with people from all over the world, and in the process, help them to achieve their language goals.

High School Immersion leader
Hi! My name is Johanna Mercedes Dima Negri and I’m from Buenos Aires, Argentina. I’m married to Mariano and have two wonderful boys, Francisco and Santiago.
Teaching is a passion I enjoy since I was a child. I can still recall when my godmother gave me as a present like a little briefcase full of chalks and a tiny blackboard to play with my teddy bears where I spent hours pretending I was a teacher. That little blackboard was not enough, and now, as an adult, I can find new ways to teach and have lots of fun, making learning a new language a pleasant moment for others.
Patience and perseverance are really important for me, because many times in life, I could accomplish things when I chose “the longest and the hardest way”, but I always look back and feel proud about it because, even though it was so difficult, I could make it. So, that is my commitment with my students, with patience and perseverance, we, as a team, are going to enjoy learning a new language.
Hi there. I’m Diana and I’m from El Salvador, a little country in Central America. I’ve been working as a teacher on different platforms since 2020. I’ve been working in CGI since 2025 as a teaching assistant. Enjoying each class helping teachers as well as students.
I like continuous professional development so at the end of this year I will complete my master’s degree in Teaching Spanish as a Foreign Language. Also I like to learn and practice languages, I speak three languages and now I’m trying to learn mandarin. I like reading fiction story books. Also in my free time I like to complete puzzles.

Spanish Instructor
Hi everyone! My name is Carlos Tomás, I’m from Veracruz, Mexico. I am a dentist and I work in private practice, where I help patients improve their oral health, something I’m truly passionate about and that gives me a great sense of fulfillment. I also have a degree in foreign languages, since I’ve loved languages ever since I was a kid. In addition to being a dentist, I work as a Spanish tutor. I really enjoy teaching languages because it allows me to help people communicate, connect with other cultures, and reach their personal and professional goals — and seeing their progress is incredibly rewarding for me.
In addition to my education and professional life, I love traveling and believe every trip is an adventure where you learn something new. I’ve visited several countries across South America because I enjoy discovering new places and experiencing different cultures. In my free time, I enjoy listening to music, playing the piano from time to time, going to the movies, and of course, trying new foods and flavors.
Hi my name is Vanessa, I’m from Mexico and I currently live in Guadalajara, Jalisco. I’m a communications graduate and since 2016 I’ve been working in social media marketing and graphic design to serve online communities and promote products and services I believe in.
I love traveling and enjoy learning about different cultures and learning new languages. I also studied some photography and in my spare time I like listening to music, watching movies and reading all types of books.
In addition to social media, I also manage our translation projects here at Common Ground.

David Riveroll Fuster
Webmaster
Hi! I’m David. I was born in Mexico City and I’ve been living for more than 15 years in a beautiful small traditional town an hour and a half away, in the state of Morelos, called Tepoztlan. It’s a magical place surrounded by mountains, with wonderful weather, great hiking tracks, waterfalls and a nice cosmopolitan community that blends with the native deep mexican culture. I live with my wonderful wife and our two daughters. We enjoy arts (music, ceramics, painting…) being in touch with nature and in the company of good friends. Recently we opened a countryside restaurant and I’m the chef and manager 😉
I love learning languages and expanding horizons through them, by allowing us to meet in between cultures and different experiences and visions. In a way, I see web development as translating and communicating with machines as well. I like to work with our wonderful team and support behind the scenes in our mission.
hello I read an article that Rory had installed and used Word Magic Unabridged Dictionary. I have used this dictionary for the past 12 years and now it is not supported on the app store. I wondered if Rory has found another app like it or something to substitute. I have found it invaluable in my quest to keep learning. Any help would greatly be appreciated. I am lost without this app.
Hello, How can I know if my Medical Spanish is good enough for your advanced course?
Thanks,
Carolyn
¡Hola, Carolyn! 👋🏽
Good question! We have a placement test to see your level and have a better idea ☺️

Interested in improving my spanish
¡Hola, Ricardo!
We are happy to help you! 👏🏽😊
I am interested in a Spanish Immersion trip to either Equador or Costs Rica for the dates approximately December 21st to December 30th of 2”24 for my family: 2 parents and a daughter who will be $ and a half. Our daughter is an intermediate to advanced Spanish speaker, but we adults are beginners . We would love to engage in all you offer : Spanish classes, volunteering, and exploration of the culture of the area. Are those programs available during those dates? Do you anticipate having any other families participating at that time as we would love to join with other families. Thanks and looking forward to hearing from you , Abigail
Hi Abigail,
We’d love to help you plan an immersion program for you and your family! Our programs are available year long but in those specific dates you’d be looking at an “off” program trip. We’d love to explain and discuss this further with you but the easiest thing would be for you to reach out via email, so please make sure to reach us either via chat or write to [email protected] so we can start planning 🙂
Hi,
I leave in Canada. I need more information for a family trip. Do your prices include a flight ticket?
I see you have immersion programs for different healthcare professionals. I’m a chiropractor in Colorado and many of us have a significant number of Spanish speaking patients. Some of us belong to integrated practices that often include a medical provider, physical therapist and others. Have you considered including chiropractors in your travel programs–with a focus on orthopedic/rehab facilities? BTW–I’m enjoying your YouTube videos.
Hi Mike, thanks for the note! Yes the medical Spanish immersion program is open to all who work in or are studying healthcare. We’ve worked with many PTs, some Chiropractors as yourself and a student or two headed toward PM&R. Immersion is the absolute best way to learn! While on program, the community outreach work we do is typically community health education – so we don’t set up or assist clinics and see patients. We do the language-rich work of educating vulnerable populations on health. In the daily classes, you would certainly have the time, opportunity and support to work on specifics around your work with patients. Thanks for checking in – we’re hoping our first post-covid trip will be July ’21. Hope you can join us!
Hi this is Gene Mandell. I am a retired teacher, still very active that lives in Central Point, Oregon. Years ago, I use to order some of these wonderful booklets(I still have a few left), and I would use them for my adult Spanish classes when I was teaching medical professionals. I am very interested in some of your programs. I will leave you my email address so you may contact me. Thank you very much.
Sincerely,
Gene Mandell
Hello Gene, thanks for the note! I’ll reach out over email.
