This is an NPI-based check only. NPISignal does not publish name-based exclusion matches on a provider profile. A shared or similar name is a lead that requires human review, not an identification, and this page is not the place to make one. Run a name-based screening below to see potential matches with the reasons for each.

An internist trained to be responsible for continuous care in the field of sports medicine, not only for the enhancement of health and fitness, but also for the prevention of injury and illness.
