Helping dogs and cats live stronger, healthier lives for longer.

I'm one of the few veterinarians board-certified in both nutrition and sports medicine/rehabilitation, and a Clinical Professor at the University of Florida. My work connects nutrition, mobility, integrative medicine, and the science of how dogs and cats age.

The goal is not just more time. It is more good time — more comfort, more movement, more joy, and more ordinary days that still feel whole.

Areas of focus

Where the work comes together.

A small set of disciplines organized around one question: what actually helps dogs and cats stay healthy, mobile, and resilient for longer?

Explore each area

Healthspan & healthy aging

What healthy years in dogs and cats actually depend on, and what the new wave of pet longevity claims gets right and wrong.

Clinical nutrition

Minimally processed diets, home-prepared food, and rigorous formulation review.

Mobility, sports medicine & rehab

Movement is one of the clearest expressions of healthy aging, and one of the most underused levers. Predominantly canine work.

Integrative medicine

Evidence-informed integration of acupuncture, rehabilitation, and nutrition alongside conventional care.

Whole-food nutrition ingredients

The work

Healthy years, not just more years.

The most important work in companion-animal medicine is not just extending lifespan. It is extending the years of full function. Nutrition, mobility, integrative care, and thoughtfully formulated supplements all converge on the same question: how do we help dogs and cats age well?

That thread runs through the work below: research, consulting, teaching, and the products I help formulate.
