St. Thomas School is proud to share that fourth-grade math and science teacher Austin Marsh has been selected as a 2026 Grosvenor Teacher Fellow through the National Geographic Society and Lindblad Expeditions.

Chosen as one of just 36 educators from across the United States and Canada, Austin will take part in a two-year professional learning experience centered on exploration, geographic education, and field-based discovery. This summer, he will travel to the Galápagos Islands aboard the National Geographic Endeavour II, where he will engage directly with scientists, naturalists, and expedition leaders while exploring one of the world’s most extraordinary ecosystems.
