Students adapt wheelchair to allow teacher's husband to take baby for a walk after brain surgery By Chip Reid Students adapt wheelchair for teacher's husband and newborn When Phoenix King was born four months ago, his parents Jeremy and Chelsie faced a difficult road ahead. Jeremy had brain surgery three years ago to remove a brain tumor, Chelsie said, which left him with what she described as "some physical challenges and physical disabilities." One big question: How could Jeremy safely take Phoenix for a walk? Chelsie, a teacher at Bullis School, a private school in Potomac, Maryland, reached out to the head of the school's technology lab Matt Zigler. He then presented the challenge to his students — including Jacob Zlotnitsky and Ibenka Espinoza, both of whom hope to study astrophysics in college.
