In an online world where everything can feel awful, Isabel Klee’s TikTok account is a welcome relief. More than a million people follow @simonsits, named after her adorable pup, and the work Brooklyn-based Klee does with other dogs — her many fosters — will leave your heart warmed like a soft buttered biscuit. Klee, 33, often takes in the most difficult cases, nurses them back to health, grants them stability and safety, then sends them off to a forever home. We all learned to be brave like Tiki, for instance, who arrived at Klee's home frightened and fragile and left steady, trusting, and sweet.

That impact has extended well beyond TikTok. Klee has translated her advocacy into a full-fledged career as an animal-focused creator, landing a book deal, major daytime TV appearances, and partnerships that funnel attention and resources back to dogs in need. What could have been fleeting internet fame has instead become sustainable, purpose-driven work.

"I feel like the luckiest person in the world to have made a career doing exactly what I've always dreamed of: helping dogs and telling stories," Klee wrote in a column for CNBC. "I have more freedom, I make more money, and I’m making a bigger impact."

So much of what we see online is powered by outrage, but Klee's platform runs on something quieter: care.
