Police and firefighters in Brookline joined the more than 200 students from The Driscoll School welcoming back a student to school for the first time in over a year.
Mateo Goldman was diagnosed with leukemia in November 2016.
Monday marked his first time back to school since the diagnosis.
“Its been a long road!! You are one brave and tough young man!,” Brookline Police tweeted, sharing photos and videos of Goldman’s first “walk back” to school.
