- 5 out of 5 starsReviewed on 1/16/2026
Dr Spragg scores the highest by every metric anyone wants to use to measure quality of care. Every time there is a decision to be made, he gives me three or more courses of action and describes the risks & benefits associated with each one. The other thing that's not worthy about Doctor Spragg is his listening capability. I know I'm not the only patient of his for the entire day, but I feel as though I am.
