Welcome to the Diabetic Foot Files Podcast and the LIMBWatch series — where diabetic foot surveillance, wound intelligence, prevention science, and limb preservation come together. I’m Dr. G / Dr. WoundPicasso aka Dr. Gabrielle Hutcheson Donaldson, podiatrist and wound care specialist, and I’m here to educate, empower, and guide you through the evolving world of diabetic foot care.

From wound healing and pressure injuries to surveillance systems and amputation prevention, we break down the science, challenge the myths, and share strategies that help save limbs and improve lives. Whether you’re a patient, caregiver, clinician, or healthcare professional, this is your destination for diabetic foot education, prevention, and preservation.

So let’s dive in — because when you take care of your feet, they take care of you.
