Our leadership team

Milena Bajtalo Martins

Head of Academics

Milena leads our academic program from Early Education through High School. A Montessori-certified educator with over 15 years at Tip Toe Discovery, she is responsible for turning our pillars into daily practice: a curriculum that merges the BNCC with international standards, and a journey where every student is closely accompanied and builds autonomy year by year.

Gregory Hal Hoyl Jr.

Educated in schools in Brazil, the USA, and Canada, and with a career in technology that took him around the world, he brings a global perspective and a systems mindset to the role.
