Meet the team behind
Ready, Set, Food!

As physicians and parents, we developed Ready, Set, Food! for our children,
because we wanted to make early allergen introduction safe and easy.

Our mission begins with a simple insight:

1 in 13 children develop a food allergy every year.

"Early and sustained introduction is hard to do on your own"

"Early and sustained introduction is hard to do on your own"

Chief Allergist Dr. Katie Marks-Cogan and her son, David

I’m an allergist and mother of two. When my son David was an infant, I introduced him to allergenic foods early and often. I couldn't believe how much work it was! Every week, I spent several hours compiling and measuring foods only to hope my son would actually eat them. I knew there was a better way. Together with Daniel, Andy, and a team of leading pediatricians, allergists, and food scientists, we developed the formulation behind Ready, Set, Food! to make early and sustained allergen introduction easy for busy families and picky eaters.

"We didn’t know about early allergen introduction"

"We didn’t know about early allergen introduction"

Co-Founder Dr. Andrew Leitner and his son, Abe

As the father of multiple children with eczema, the biggest risk factor for food allergies, I'm dedicated to teaching parents about early allergen introduction.

Ready, Set, Food! was launched in 2018 in Los Angeles, CA with a vision to make it easy for all parents to frequently feed allergens to their baby.
