About
Whole-food nutrition for busy families
Rosalind Achterberg completed the Ulan Nutritional Systems advanced clinical program and holds certification as a Certified Natural Health Professional. She does not hold a state medical license and says so plainly on her intake forms.
Her practice centers on families: parents with persistent fatigue, kids with picky eating and digestive complaints, and grandparents who want to stay independent.
She keeps outcome records for every client and shares anonymized 90-day results with PHN as part of her founding application.
Specialties
Approach
A three-phase model, so you know what happens at each stage and what you leave with.
01
Assessment
A 75-minute intake and assessment, plus a food and symptom diary for two weeks.
02
Strategy
A whole-food plan with a short, specific supplement list and a written grocery guide.
03
Execution
Check-ins every two weeks for the first three months, with referrals out when something needs a physician.
What clients say
She was honest about what she could and couldn't help with, and what she could help with, she did.
My whole family eats differently now. Nobody feels deprived.
