The Harbin Clinic now has more than 27 satellite offices throughout Rome, Adairsville, Bremen, Calhoun, Cartersville, Cedartown, Summerville, and Trion.

Common health problems included smallpox, diphtheria, typhoid, pellagra, tuberculosis and diabetes, with diagnosis depending on active symptoms, physical findings, and sputum examinations.

In 1908, Robert and Will founded the Harbin Hospital with 12 beds by converting a house at the Southeastern corner of Third Avenue and First Street.

Many modern systems were included, such as steam heating, electrical lights, silent call systems, hot and cold running water in each room, linoleum floors, three complete operating suites, a private telephone exchange, and a safe-gate elevator running from basement to roof.

In 1925, the Harbin Hospital introduced what was then an innovative orthopedic program of following the treatment of bone fractures with physiotherapy (known today as physical therapy).

The next major change came in 1969, when the medical group purchased 8 acres (32,000 m2) from Berry College on the Southwest corner of Martha Berry Boulevard and Redmond Road, and built a new facility with 34,000 square feet (3,200 m2) of office space for a staff of 20 doctors, a dentist, and a pharmacy.
