I work with brands, organizations, and media platforms that want to support children and families with credible, evidence informed nutrition guidance.

With more than 35 years of experience in pediatric nutrition, feeding, growth, and child development, I bring together deep subject matter expertise with the ability to translate nutrition science into practical guidance parents can understand and use.

My partnerships range from strategic advisory and product guidance to YouTube integrations, podcast sponsorships, educational campaigns, spokesperson work, and media collaborations.

Reach Parents Through Trusted Nutrition Education
