At Leonie Health, we are driven by the fierce compassion and protective strength embodied in our name—Leonie, meaning lioness. Just as a lioness safeguards her young with unwavering resolve, we are committed to transforming neonatal nutrition for the most vulnerable infants with bold innovation and maternal care.

Founded by pioneers in human milk science, clinical medicine, and healthcare innovation, Leonie Health brings together a team whose collective impact has shaped the very foundations of neonatal nutrition. From launching the world’s first human milk-based fortifiers to scaling hospital systems and advancing infant gut health, our founders—Elena Medo, Adrianne Weir, and Dr. David Kyle—have created and led companies that changed how hospitals nourish premature babies.

Our team includes experts in neonatology, pediatric gastroenterology, immunology, regulatory operations, and strategic communications. Together, we are building a new standard of care—one that integrates bioactive human milk therapeutics into NICU workflows, supports immune development, and reduces complications like necrotizing enterocolitis (NEC).

Leonie Health’s name reflects our essence: strength in science, courage in innovation, and deep care for every infant we serve. With patented technologies, clinical partnerships, and a shared vision for healthier beginnings, we are leading a movement to elevate neonatal care—one drop, one baby, one breakthrough at a time.
