​Leslie R Kowalski, PhD, IBCLC

Leslie has been providing breastfeeding support in the Princeton area for over 15 years - as a La Leche League (LLL) leader since 2002, a board certified lactation consultant since 2011, and with Mercer County WIC since 2014.


Leslie grew up in both New York and New Jersey. She graduated from Cook College with a BS in Biochemistry, and from Rutgers University/UMDNJ with a PhD in Biochemistry and Molecular Biology.  While raising her children, Leslie's difficulties with early breastfeeding experiences, and challenges with return to work issues laid the foundation for her understanding of the importance of skilled lactation support.


Leslie is an in-network provider with Aetna insurance, a member of the International Lactation Consultants Association (ILCA), the United States Lactation Consultants Association (USLCA), and the New Jersey Breastfeeding Coalition.
