Dr. Alex Leasure

I was born in Jacksonville, FL and attended University of Central Florida in Orlando for my undergrad in biology. I later went through EMT training but never worked as an EMT, that was my first introduction to the medical field. I attended medical school at the University of Queensland in Brisbane, Australia. It was a unique program that formed from a partnership between the University of Queensland and Ochsner Health System in New Orleans. We did our first 2 years in Australia and our clinical rotations at a large hospital in New Orleans. After med school I completed a Family Medicine residency at the University of Florida in Gainesville. My professional interests include point of care ultrasound, suturing techniques, and infectious disease. Outside of work, I coach at a local crossfit gym, enjoy surfing, spearfishing, stand up paddling, rugby, cooking, fermentation, and cycling. I met my wife, Marie Claire Lamb, in med school while playing touch rugby. I proposed to her some years later, while surfing. She also works at Sansum as a primary care physician and volunteers with DWW. I have 2 hound dogs named Quincy and Fiona and they are both hilarious.
