A Legendary Zoo Vet's Secret? It All Starts With People.

Don Janssen, the kind of wildlife veterinarian who shaped entire institutions, had a simple, slightly ironic philosophy: to truly care for animals, you first had to care about people. Which, if you think about it, makes perfect sense, even if it sounds a bit like an ancient proverb whispered by a wise, slightly grumpy mentor.

Janssen, who dedicated over three decades to the San Diego Zoo and its Safari Park, learned this critical lesson the hard way, early in his career. He figured loving critters more than humans was a solid professional strategy. Turns out, not so much. A seasoned vet pulled him aside and delivered the blunt truth: If he didn't master the art of human interaction, his career would be a constant battle, and the animals? They'd be the ones paying the price. It was a piece of advice that stuck with him, probably echoing in his head every time a committee meeting went sideways.

The Human Element of Healing

After graduating from the University of California, Davis, in 1978, Janssen didn't just join the field; he helped define modern zoological medicine. He rose through the ranks at the San Diego Zoo, eventually becoming the director of veterinary services and then the vice-president of animal health. His purview wasn't just fixing a broken wing or diagnosing a mysterious ailment; it was about orchestrating a symphony of care, a complex dance that involved scientists, zookeepers, administrators, and yes, even the occasional celebrity donor.

His career was a testament to the idea that even in the wild world of animal care, the most unpredictable, and often most crucial, variable is us. Because when it comes to saving a species, sometimes the biggest hurdle isn't a rare disease, but getting a dozen very passionate people to agree on the best way forward. And that, apparently, is where the real animal magic happens.
