About

Hi, I’m Kelsy.

I live with POTS, MCAS, hypermobility, and fibromyalgia. I’ve written three books about it, I share real life with 25K people on TikTok, and I’m working toward my Board Certified Patient Advocate credential. Most days I’m somewhere between a training run, a book idea, an appointment, and figuring out dinner. This site is where all of it lives.
