About the Children’s Clinic

NAM’s Children’s Clinic offers quality medical care to infants and children through age 18 for families who have Medicaid, Children’s Health Insurance Program (CHIP), private insurance, or who are self-pay/uninsured. The Clinic provides a full range of services, from preventative care to acute care.

Physicians, nurses, a medical assistant and a team of support staff and volunteers work together in the Clinic. They take into account the child’s overall health, nutrition and home environment to treat the whole family.

The Children’s Clinic is a unique partnership between NAM and the University of Texas Health Science Center – Houston, making our expertise second to none. While bringing excellence to our patients, the clinic also serves as a training facility for the University of Texas Health Science Center and other local universities and community colleges.

The Clinic also offers the Reach Out & Read Program, which includes a prescription to parents to read to their children 20 minutes a day. The Clinic provides books to all patients through donations from the Rotary Club of Willowbrook, Girl Scouts, Boy Scouts, individuals and businesses.

Honors and Awards

NAM Children’s Clinic was awarded the 2015 Quality Award for Excellence in four domains of quality: Well Child Care, Adolescent Well Care, Treatment of Respiratory Illness, and Asthma.

The clinic received Quality Awards in 2013 and 2014 as well.

In addition, Dr. Lisa de Ybarrondo, pediatrician at NAM’s Children’s Clinic, was awarded the Dean’s Teaching Excellence Award from the University of Texas Medical School for excelling in their teaching of medical students.

Congratulations to all of our Children’s Clinic team!

Maria’s Story

When Maria’s baby girl was just four months old, she was diagnosed with Glycogen Storage Disease Type Ib, which interferes with how the body turns food into energy. Doctors at Memorial Hermann referred Maria to the Children’s Clinic at NAM to help manage and care for her daughter’s special needs.

Today that little girl, Genesis, is a beautiful, curious five-year-old and a caring sister to her two younger brothers. All three children receive their medical care from the Children’s Clinic at NAM.

“It’s a good clinic,” says Maria, who is a single mom. “Honestly it’s been hard, but they’ve helped me a lot with Genesis.”
Maria gives her daughter daily shots to boost her white blood cells, and a home nurse is present Monday through Friday to give Genesis the IV nutrition she needs every few hours. NAM’s Children’s Clinic helps coordinate those supplies and services, as well as appointments with specialists.

The Clinic was also there to help when bed bugs found their way into Maria’s home. Infection from the insects could have been fatal for Genesis, so the Clinic’s new Pediatric Intensive Case Management program paid for pest control services, and then replaced all of the family’s furnishings. New beds were purchased; a family at one of NAM’s IHN congregations donated living room and dining furniture; and NAM’s resale store came through with the remaining items.

And because of neighbors helping neighbors, one very special little girl receives life-saving help.
