Our Staff


Founded in 1996, we were the first private medical practice in the United States to focus exclusively on the specialty of breastfeeding medicine.  In the twenty years since Breastfeeding Resources was founded, we’ve grown and shrunk and grown again, as our all-mother clinical staff have each negotiated the complicated paths that criss-cross between nurturing breastfeeding families and nurturing our own families.

Clinical staff
  • Sue Iwinski, IBCLC, is board certified by the International Board of Lactation Consultant Examiners, and has been with our practice since 2000. Her attention and care with each and every family draws many mothers to our practice by word of mouth. This thoughtful approach to each family, as well as her clinical expertise and insight, have set the tone for our practice, individualizing care to each family’s circumstances. A leading voice for babies in her role with Connecticut’s La Leche League, she speaks regularly at League annual conferences. She has two adult children, and is lead vocalist for AfterShock, Connecticut’s powerhouse danceable rock band.
  • Marissa Mesiya, APRN, IBCLC, our newest provider, comes to us from Canterbury Pediatrics, where she worked both seeing children of all ages in primary care pediatrics as well as supporting breastfeeding mothers and babies with her expertise as a lactation consultant. The mother of two breastfed children, she loves her work, and families love her. Some years ago, when first studying for the big IBLCE exam for lactation consultants, she spent a year and a half interning with us. We are happy to welcome her home!
  • Sue Marchitto, APRN, IBCLC, is also certified by the International Board of Lactation Consultant Examiners. She works partttime with us, and remains a valuable member of the Yale Health Plan pediatrics team, sharing her breastfeeding expertise with families both in New Haven and with us. We are so grateful to have her wisdom, experience and expertise.
  • Maria del Mar Mazza, RN, IBCLC, is also a lactation consultant certified by the International Board of Lactation Consultant Examiners. She is fully  bilingual, seeing both English and Spanish speaking families. She came to us with an extensive resume, including many years as principal Spanish translator for La Leche League International. She translated Dr. Smillie’s DVD, the Mother-Baby Dance. We share her with Yale New Haven Hospital’s maternity floor, where she supports new mothers and their newborns just learning to breastfeed.
  • Lisa Papp Terifay spans both the administrative and clinical sides of our practice. A welcoming and cheerful receptionist, she is both tech savvy and breastfeeding knowledgeable. She takes on a wide variety of techy projects for us, and, most importantly, organizes and facilitates our weekly mothers’ support group. The mother of three previously breastfed children, she for many years was a volunteer leader for La Leche League International, giving her broad experience supporting breastfeeding mothers. Her busy family life willing, we hope she will soon be working towards lactation board certification by the IBLCE.
  • Christina Smillie, MD, FAAP, IBCLC, FABM, our founding physician, devotes full time to clinical practice at Breastfeeding Resources, while finding occasional time to speak both nationally and internationally. Board certified as both pediatrician and lactation consultant, she is a Fellow of both the American Academy of Pediatrics and the Academy of Breastfeeding Medicine. She has two adult children and one grandchild, still thriving on his mama’s milk.

Coming soon, Laurie Rubel, APRN, and Liza Goldman Huertas, MD. Watch this space for more info.

All of us have experience balancing the juggle of managing family responsibilities with employment, and we’ve also each spent a chunk of time as stay-at-home mothers, working exclusively inside the home with our young children.
