Popovich was born with achondroplasia, a genetic disorder that restricted the growth of her limbs.[2] Her parents, a teacher and a physician, moved their family to Butte, Montana when Popovich was five.[3] During childhood, she wore braces to straighten her back and legs, and underwent about a dozen surgeries. But according to her mother, "we didn't have to make a lot of accommodations for her; we didn't want to treat her too much differently from her siblings."[3] Popovich was interested in sports from an early age. She rode horses and played soccer and basketball. When Popovich was 12, she joined a swim club and by the age of 15, she was competing at the 2000 Paralympic Games.[3]
