We had a truly special 3 month Boundless cohort in Sintra, Portugal in September. We were new to Boundless Life and our experience exceeded our expectations. The community and school teams in Sintra worked well together to support the group in forming meaningful community. The education team were wonderful. Our kids skipped happily into school and were excited by their learning. We were inspired and touched by the whole experience and have booked another 3 cohorts since!

Our time in the Sintra Portugal cohort was transformative for us and our 5yo son. We enjoyed every minute from the amazing school and teachers to the beautiful surroundings. We liked seeing our son grow exponentially over just 3 months in his academics, social skills, and curiosity. Something that lacked from all of his US schools. The families were amazing and the community that boundless has set up made the experience very unique. We loved the school and the teachers and alongside the amazing community staff made the cohort unforgettable.

Our trip to Sintra, Portugal was everything we could have wanted when traveling with young children. Both my kids (8 year old boy and 5 year old girl) said their favorite part of the trip was the school. We were able to connect with the country, immerse ourselves in the culture and most importantly, connect with ourselves. We will definitely be back for another boundless experience.
