When Holly was diagnosed with diplegic cerebral palsy in both legs, she began seeing physiatrist Sue Mukherjee, MD. Initially, Holly needed a walker to get around her preschool classroom. But Dr. Mukherjee firmly believed she wouldn’t need one at home—because she’d be walking on her own soon enough.

“It’s like she has a crystal ball,” says Holly’s mother Amanda. After 6 months of physiatric therapy with Dr. Mukherjee, Holly doesn’t need a walker at all anymore. “Holly has a special bond with her,” Amanda says. “At our last appointment, she and Holly walked up and down the hallways for a long time just waving at everybody.”
