Klein has an extremely uncommon kind of dwarfism called Spondyloepiphyseal dysplasia, Strudwick type, and is just 3 foot 2 inches tall. Her husband, meanwhile, stands slightly taller at roughly 4 feet and has the condition Spondyloepiphyseal dysplasia, known as SED. What’s more, the pair have between them undergone over 50 surgeries designed to keep their knees, hips and ankles in working order.
Now a lot of the show follows Arnold at work in her highly specialized job. However, the reality TV doctor had to convince the Texas Children’s Hospital to allow cameras in the building. “When the show became a reality, we got in touch with the PR folks there, but there was a lot of hesitation. As a hospital, they have a lot to lose, and they wanted to make sure it would show the hospital in a good light,” she told Glamour in 2013. “And now, it has turned out to be this great relationship.”
Arnold may be small, obviously, but more importantly, she’s an incredibly talented doctor. She studied at the John Hopkins School of Medicine, completed a pediatric residency program at the Children’s Hospital of Pittsburgh and obtained a master’s in medical education from the University of Pittsburgh in 2007. Plus, she’s picked up multiple awards for her medical skills and good bedside manner.
