Welcome to the Cambridge Health Alliance family!

Dear Provider,

It is my pleasure to welcome you to Cambridge Health Alliance (CHA). CHA is a mission-driven academic community health system dedicated to improving the health of our patients and communities. We have special expertise in caring for those who feel marginalized or face barriers to care, and we recruit, develop and retain a diverse and high performing workforce committed to making a positive difference.

At CHA, you will enjoy working in an exciting and integrated environment that provides unique and vital health services to our communities. Our passionate providers and staff fuel a workplace community that always pushes to identify innovative ways to deliver care and adapt to the evolving national healthcare landscape. Provider and employee engagement are critical components of our culture as we aim to inspire our employees and empower them to do great work for our patients and communities.

CHA requires all new medical staff members to successfully complete a comprehensive provider orientation. The orientation process meets regulatory compliance requirements and also provides new medical staff members with an overview of our services, systems and processes, and ensures that you have knowledge of and access to a variety of available resources. We have designed this orientation page to acquaint you with CHA’s governing documents and other policies including benefit information. We welcome you to contact my office at 617.665.3130 if you have any questions regarding the orientation process or any general feedback.

Our goal is to nurture and support our providers to help them serve our patients to the very best of their abilities. We are committed to a robust on-boarding program to ensure you are successful.

Welcome to CHA!
