Individualized nutrition support to optimize your child’s health

Nutrition is a key part of any medical treatment plan. That’s why DMG Children’s Rehabilitative Services (DMG CRS) includes registered dietitians and nutritionists to support your family.

DMG CRS regularly treats pediatric patients affected by nutritional deficiencies/disorders, obesity, chronic illness, and eating disorders. Our dietitians are industry experts specializing in care of pediatric patients with a variety of complex conditions with unique nutritional requirements. Our areas of expertise include:

  • Feeding problems

  • General nutrition planning

  • Ketogenic diet to aid in the treatment of epilepsy

  • Special formulas

  • Tube feeding

  • Weight management

Our pediatric dietitians will work one-on-one with you and your child to help you select appropriate healthy foods, vitamins, and minerals to improve overall health and target specific medical conditions.  We also recognize the existence of cultural and familial eating preferences, and our skilled nutritionists will incorporate such preferences in dietary planning programs.
