Board of Directors


President: Amanda Koellhofer, B.A.
A former donor mom, Amanda brings more than 15 years experience in marketing and event planning to the MMBA board.

She is involved in her church and dedicated to service — especially for kids and families. Amanda loves to read, spend time with family and friends, and travel with her family.

“I learned about the Milk Bank when I had a freezer full of breastmilk near expiration that my twins would not need. I discovered the Mothers’ Milk Bank at Austin, and I am so proud of the donations I made. The volume of milk that would feed my boys for a few days could feed many sweet babies fighting for their lives for much longer. My breastfeeding days may be gone, but not my passion for saving the lives of babies with a critical need for donor milk. The community created through mothers donating milk, families supporting our Charitable Care program, babies thriving because of another mother’s gift, and recipient family’s appreciation is simply beautiful.”


Immediate Past President: Peter Untalan, MD
Peter has been providing neonatalogy services with the Pediatrix Medical Group of Austin since 2002. He is driven to ensure the best care to infants, children, and their families. Dr. Untalan, a strong supporter of the power of nutrition and breast milk, served as the President of the Mother’s Milk Bank at Austin from 2010-2015. He received his medical degree from the University of Hawaii at Manoa and performed his residency at the University of Texas Health Science Center at San Antonio. Peter is thankful for the constant support of his wife Sydney and three children, Antonia, Pedro, and Frances.

“Working with the milk bank is a life mission, because I want to ensure the best nutrition is readily available for our most at-risk babies.”

“While pregnant with my first son fifteen years ago, I learned about the milk bank from a TV news story and immediately knew I would become a donor. I could not fail to help those tiny babies when I was able to provide something—mother’s milk—that few others could. I pumped every day for a year, only for the milk bank, and did the same after I had my second son. I joined the board in 2009 and have served as treasurer and secretary. Helping the milk bank grow and prosper, expanding its reach and diversifying its offerings, has been tremendously fulfilling.”

Moms volunteer and donate human milk that nourishes tiny preemie babies in need. And MMBA insures that this life-saving milk is safe and effective for these at-risk infants.”

“As a nurse, mother, and IBCLC, I have learned over the years how important breast milk is for all babies. Not all families are well informed on the benefits of breastmilk, however, so parents need education and support to make the best decisions for their family. For fragile babies in a hospital Neonatal Intensive Care Unit, prescribed donor milk from a milk bank is the next best thing, if mom's own milk is unavailable. Breastmilk is a limited and very precious resource, so we need more healthy mothers to breastfeed and donate.”
