Each firm in the Johns Hopkins medical residency firm system, which is in its 46th year, now has a head — an assistant chief of service (ACS), who is a junior faculty member — and house staff members, nurses and hospital space. The firms are named for the four men who led the Department of Medicine between its original director, William Osler, and A. McGehee Harvey. The ACS is a physician of record for each firm for one year, starting in July.

We welcome this year’s assistant chiefs of service and wish them well. In the photo below, from left, are John Wells (Thayer Firm), Alexandra Horne (Longcope Firm), Tijana Tuhy (Janeway Firm) and Bryan Broderick (Barker Firm).
