How to choose the right specialist
Verify board certification, ask how many of your specific procedure the clinician performs each year, and review patient outcomes — not just star ratings. A internists provider who clearly explains your options, the evidence, and the realistic recovery timeline is worth more than the most heavily advertised name.
