Somos CLU

Whitman Suárez

My fascination with language acquisition has shaped my entire professional journey. I’ve worked as a teacher, language coach, researcher, entrepreneur, and education leader for more than 20 years, specializing in how the bilingual brain works and how learning processes can be optimized.

At CLU, I help learners overcome fear, build confidence, and develop the ability to communicate effectively and authentically in another language. I firmly believe that everyone can acquire a second language with the right guidance, consistent action, and a personalized plan. I’ve had the privilege of supporting more than 1,000 learners, from beginners exploring a new language to CEOs using a second language to expand their businesses.

Outside of my work, I enjoy playing soccer, biking, and exploring new
technologies.

Diana Pedraza

I’m a linguist and philologist with dual Master’s degrees in Linguistics and Teaching as a Second Language. My academic and professional path has focused on understanding how languages are acquired and processed in bilingual and multilingual minds, both in children and adults.
At CLU, I design and guide language coaching experiences that go beyond traditional instruction. I help learners unlock their voice in another language by building confidence, self-awareness, and strategies that align with how they think, learn, and communicate best. My goal is for each student to feel empowered, clear, and authentic when using a second language in real-life
contexts.
When I’m not coaching or researching language acquisition, I enjoy healthy cooking, dancing, singing, traveling, and spending quality time with my family.

I am a committed and innovative language educator with a Bachelor’s degree in Bilingual Education and a strong passion for teaching, effective communication, and continuous professional development. I specialize in creating engaging and supportive learning environments that foster students’ confidence, critical thinking, and language proficiency. Beyond my professional responsibilities, I enjoy reading literature and philosophy, playing the guitar, exploring different cultures, and learning new languages. My goal is to continue strengthening my teaching expertise, embrace new professional challenges, and contribute to educational excellence through creativity, adaptability, and a lifelong commitment to learning.

Felipe Hernández

I hold a degree in Bilingual Education and have experience coaching
teenagers and adults from diverse cultural and professional backgrounds. I
consider myself a lifelong learner, tech-savvy, creative, and deeply interested
in how people use language to express ideas, emotions, and identity.
Having grown up bilingual, I understand first-hand how language shapes
the way we communicate and connect with the world. At CLU, I help
learners develop practical, goal-oriented communication skills, whether for
executive presentations, construction-related contexts, or job interviews. I
believe language learning is a lifelong process, and the more we use a
language, the more confidently we can express who we are.
In my free time, I enjoy going to the gym, singing, voice acting, spending
time in nature, and playing video games. I look forward to coaching you in
your language learning journey.

I have a Bachelor’s degree in English and English Literature. I’ve been teaching English for  12 years and have had the pleasure of meeting and working with students from all different professional backgrounds and levels. I love developing amicable relationships with my students and helping them acheive their professional/personal English goals.

Kathryn Griffin

I’m originally from Chicago, Illinois, and Colombia was my home for over 20 years, where I worked as a teacher, professor, coach, and academic advisor. I hold an undergraduate degree in Journalism, Anthropology, and International Studies from Indiana University, as well as a Master’s degree in the Didactics of English from Universidad de Caldas.

I strongly believe that language development is deeply connected to academic growth and professional advancement. At CLU, I coach learners who are pursuing meaningful goals, such as studying abroad, earning scholarships, or advancing in their careers. The most rewarding part of my work is seeing students gain the confidence and linguistic tools they need to open new doors and move forward with clarity.

In my free time, I enjoy spending time with my two dogs and playing the piano.
