DMG CRS nutritionists and dietitians are industry experts specializing in pediatric care. In collaboration with DMG CRS medical specialists, our team of highly-trained professionals will provide customized, individual nutritional plans and patient education designed to properly support various medical needs and conditions. DMG CRS regularly treats pediatric patients affected by nutritional deficiencies, disorders, obesity, chronic illness and eating disorders. Our nutritionists are also educated in the Ketogenic diet to aid in the treatment of epilepsy.

Our areas of expertise include:

  • Feeding problems
  • General nutrition planning
  • Special formulas
  • Tube feeding
  • Weight management 

Our pediatric dietitians work one-on-one with parents and their children to help them 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.
