Andrea Castell

I was born and raised in Buenos Aires, Argentina. My deep love for this city and my country inspired me to share their cultural richness and unique spirit through thoughtfully curated, exclusive experiences.

With over 25 years of experience in the humanistic field, I have built my career as an ontological coach specializing in personal and professional development. I founded Centro Path and Path In Company, organizations dedicated to individual and corporate well-being, supporting deep and lasting transformation. I am also the author of several personal development books available on Amazon.

My passion for travel grew as I explored the Americas, Europe, and Asia alongside my partner, a cruise ship captain. These international experiences allowed me to connect with people from around the world, experience life on luxury cruises, understand premium hospitality, and truly learn what it means to provide attentive, personalized, and high-level service.

This is how GreatCircle was born: a travel services company I founded in 2024, specializing in Tours, Retreats & Cruise Relations, based in Buenos Aires. Our mission is to create uniqueexperiences in Argentina, focusing on detail, service, gastronomy, adventure, culture, and the identity of each place. Combined with my commitment to social and environmental impact, this philosophy guides every experience we design at GreatCircle. We also offer bespoke trips and wellness immersion retreats, blending personal development with cultural exploration to create authentic, transformative, and memorable experiences.

CEO of GreatCircle

Yannina Krbavcic

I am passionate, curious, and naturally entrepreneurial. I turned my love for sports and travel into my lifestyle, and since then I have been building projects that connect people, experiences, and opportunities with purpose.

I was born and raised in the Argentine Patagonia. I studied Psychology and Social Responsibility, and over the years I have developed a solid career in marketing, corporate production, and international events, combining strategic vision with hands-on execution. I also spent many years on the ATP Tour accompanying my former husband, a professional tennis player. As Founder and Director of KRB Group, I led projects that integrated creativity, planning, and high-level relationships. I developed strong organizational skills, team coordination, negotiation expertise, and comprehensive project management, always focused on excellence and results.

I love traveling because every destination broadens my perspective and fuels my creativity. Today, alongside Andrea Castell, I have found at GreatCircle the ideal platform to fully deploy my expertise — a space where I integrate my experience in travel, events, and production, my strategic vision, organizational skills, and my passion for connecting people and creating real value.

Stories from Satisfied Customers

I had always dreamed of visiting Buenos Aires, and it truly exceeded my expectations! I’m grateful to GC for guiding me in planning and enjoying the best experiences.

My husband and I hired GC Tours for 3 days, and everything was wonderful. We loved the Tango show, the barbecue in the countryside was amazing, and the tour around charming Buenos Aires! We want to come back soon!

We were recommended to book tours with GC, and now we recommend them to our friends, as it was an exceptional trip. Argentina and its people will stay in our memories, and we would love to return!
