TESTIMONIALS
"My son has been under the care of Professor Rosan Meyer for over five years, and I cannot recommend her highly enough.
Rosan supported us through the desensitisation process for my son’s dairy and egg allergies, carefully guiding us through the milk and egg ladders while also designing a safe, nutritionally balanced dairy/egg-free diet during the period when his allergies were still active.
She has also provided outstanding support around my son’s extremely selective eating. Rosan recommended appropriate vitamin and mineral supplements, shared practical strategies to manage his food sensitivities, and suggested recipes and products that have helped ensure he continues to grow and thrive.
What truly sets Rosan apart is her responsiveness and care. She always replies quickly, even through we don’t expect it, and no question ever feels too small or trivial. She takes exceptional care to ensure that the most appropriate supplement, strategy, or intervention is in place.
Rosan is, without question, the most knowledgeable and experienced paediatric dietitian. She has authored numerous scientific papers and consistently bases her recommendations on robust research. Combined with her warmth, empathy, and genuine commitment to her patients, this makes her an incredibly trusted professional. I recommend her to anyone in need of expert paediatric dietary support."
