About Us



Cadence Healthcare Systems was founded with the vision of transforming healthcare practices by optimizing business processes and implementing creative and cost effective solutions. Cadence Healthcare Systems provides Business Process Co-sourcing to physician groups and individual practices. The business model focuses on a co-sourcing approach which allows each client to identify services to be fully transitioned to Cadence Healthcare Systems and determine the continued level of involvement by its staff.

Cadence Healthcare Systems’ principal office is in Los Angeles, California.

Cadence Healthcare Systems provides specialized business process operations that are customized to account for the provider clinical specialties, patient mix, unique payer mix, and regional markets of its clients. The increasing costs of delivering healthcare, decreasing reimbursements, fast-moving evolution of technology and changing models of physician and patient relationships are causing physician groups to re-define all components of how they operate a business and provide clinical care.

Cadence Healthcare Systems has developed a comprehensive service model which will allow healthcare providers to concentrate on patient care and rely on Cadence for business operations.
