Our Story

Our mold journey began years ago with an intermittent, musty smell in our bathroom, despite no visible source. My father, a licensed contractor, advised against tearing into walls without a clear reason. But when my husband started experiencing strange, unexplained symptoms, and I was battling ongoing flare-ups from Hashimoto's, I knew we had to look deeper.
That’s when I discovered mold detection dogs—specially trained to locate hidden mold with speed and accuracy, without the cost, damage, or guesswork of traditional methods.
Three years earlier, we had begun training our dog, Arizona, with the hope she’d become a therapy dog, but her high energy and strong work drive told us she was meant for something more. I soon discovered my own passion for dog handling and began training alongside professionals.
Once we learned how impactful mold detection dogs could be, it all clicked that Arizona had the perfect temperament for detection work, and I had found my calling.
Now, with Mold K9 Detection Services, our mission is simple: to help Florida families find hidden mold and create safer, healthier spaces—without unnecessary damage or stress.
