Maura & Gretchen are co-founders of the Little Zebra Fund. Their paths first crossed during medical genetics fellowship training, where they discovered a mutual desire to solve the health inequity facing many of their undiagnosed patients. This shared passion led to the creation of the Little Zebra Fund.


Maura RZ Ruzhnikov, MD & Gretchen Kissel Foskett, MD

The decision to name the organization The Little Zebra Fund was as clear as the problem they planned to address.
There is a well-known aphorism used in medical training to remind physicians
to consider more common diagnoses first.

When you hear hoofbeats, think of horses not zebras
— Dr. Theodore Woodward

As geneticists, we specialize in making rare diagnoses after the more common diagnoses have been ruled out.
Thus, Little Zebras affectionately refers to the patients we serve & treat.
