Noble Health Alliance, a venture founded last year by Abington Health, Aria Health System, Crozer-Keystone Health System, and the Einstein Healthcare Network, said that two physicians groups have joined the organization.

The addition of 64 doctors from Premier Orthopedics and Cardiology Consultants of Philadelphia means that the Noble Health network now has more than 1,800 primary care physicians and specialists in Southeastern Pennsylvania.

Without formally merging their operations, Noble Health is attempting to build a clinically integrated network of doctors and health systems to better coordinate and manage health care.
