Johns Hopkins Medicine On-site

JHAH launches its 2025 program of on-site rotations

JHAH is proud to announce the start of our 2025 JHM On-site program. Continuing with our person-centered care model, Johns Hopkins Medicine (JHM) On-site has Johns Hopkins Medicine expert physicians from a wide range of specialties share their expertise during ongoing medical rotations on the ground at JHAH, from reviewing cases, providing patient consultations, to performing surgeries for our patients.

Depending upon their area of expertise and clinical specialty, JHAH will provide registered patients with details for requesting a consultation with the physician, as the criteria may differ for each specialty. Other JHM On-site physicians will be pre-scheduled for complex cases and procedures.
