Dr. Martin Osler, PhD, Veterinary Science Researcher & Formulator, created Osler with his own rescues Leo and Luna in mind — combining a lifelong love of pets with rigorous science to create better everyday care for the animals we call family.

EVERYDAY CARE, MADE SIMPLE

MEET LEO

The rescue who started it all.

Leo came into Dr. Martin Osler’s life as a spirited little rescue with a huge personality. Caring for his sensitive skin, paws and everyday needs pushed Martin to look beyond conventional pet care and begin formulating solutions of his own.

MEET LUNA

When Luna joined Martin and Leo, she brought a whole new set of needs — and an important realization: cats deserve care designed specifically for them, too.

Her sensitive nature helped shape Martin’s belief that everyday pet care should be gentle, thoughtfully formulated and safe for the animals we love.

MEET MARTIN

The man behind the mission.

For Martin Osler, better pet care started at home. After rescuing Leo — and later Luna — he began questioning what was inside the everyday products he was using on the animals he loved.

That personal search became a simple mission: create thoughtful, science-led pet care designed with the same attention we expect from our own personal care.

Two rescues. One personal mission. Osler.
