About Allison

Allison is the founder of Flora & Fauna Nutrition, where she specializes in providing critical gut health and nutrition information for preconception, pregnancy, postpartum and baby’s first 1,000 days. She started her career as a microbiologist and has expertise in the gut microbiome and how our microbiome impacts our holistic health. Her journey into nutrition started when she learned how fundamental the food we eat is for our microbiome and overall health, including immunity, skin, mood and hormone balance. She believes that the foods one eats are the foundation of nourishing not just a healthy body, but in the case of pregnancy, the expectant babies as well. Shocked by a lack of nutrition guidance she encountered in her routine prenatal care when pregnant with her first child, she is passionate about educating the holistic health benefits of a well-balanced diet, and how this supports proper gut health, optimal pregnancy and fetal development and postpartum recovery. Her hope with providing this critical nutrition information is to give babies the absolute best foundation to lifelong wellness and to help mothers not only recover, but thrive, to be able to feel their best for themselves, their families and their community.
