Dr. Jonathan Goldfinger, MD, MPH, FAAP

Our pediatrician is not only knowledgeable, experienced, and Board-certified--he's as breastfeeding-friendly as doctors come!

"As latchMD's owner and lead pediatrician, I love that we offer a team-based approach to breastfeeding, newborns, and pediatric care.  We guide families with the most up to date research, so you can really trust the advice you receive.  Our interdisciplinary teams and network include pediatric-trained, breastfeeding experts--doctors, nurses, lactation consultants, registered dietitians, and occupational therapists who work together for your family!  The entire team discusses your case to ensure that all of your concerns are addressed, from the most basic to the most complex.  No two mothers or babies are exactly alike so we tailor our guidance to meet your specific needs.  Non-judgmental support in line with your beliefs and goals for your child is a hallmark of our care.  Let us bring latchMD's village of experts to you today!"

Debra Diaz, IBCLC

Our caring, experienced lactation consultant offers compassionate, family-centered care from your home or truly anywhere! 

"I feel honored to help new mothers breastfeed through the latchMD family.  As an Internationally Board Certified Lactation Consultant (IBCLC), I have always enjoyed working with other healthcare providers to offer high-quality services for families.  Through years doing home visits I've learned that many breastfeeding issues require a doctor.  Even great pediatricians aren't always free in your first weeks home, and many don't feel comfortable helping babies latch or treating sore nipples.  Some quickly recommend formula when breastfeeding becomes challenging or babies lose weight, which can be very upsetting to moms trying so hard to breastfeed.  At latchMD we work with physicians who know a lot about breastfeeding and monitor the health of every mother and child.  Our new moms rest easy having the whole latchMD team at their disposal.  The results are magical for everyone."
