What patients say

Patients praise

  • Some Aspirus endocrinology providers have high patient ratings and positive commentary (e.g., Katy Anderson: 4.8/5 with many ratings/comments).
  • Hospital-level patient recommendation metrics are relatively positive (e.g., U.S. News: 86% willing to recommend).

Common complaints

  • Some individual reviews for an Aspirus endocrinologist (Dr. John E. Carroll) include complaints about missing diagnoses, unnecessary testing, prescription follow-through, appointment cancellations, and poor follow-up; these align with low ratings on Vitals and low patient-experience scores on U.S. News.
  • Some sources show lack of ratings/reviews for the specific Rhinelander endocrinology practice page on WebMD (0 ratings).

In patients' words

"“Outdated knowledge not in touch with up to date treatments. Will not listen, runs unnecessary tests, doesn’t get prescriptions in on time. Cancels appointments and blames the patient… Doesn’t get back to patient with results. No follow up with treatment.”"
