Sierra has decades of experience helping clients enhance their revenue cycle performance across various markets and multiple specialties. We focus our efforts and invest in the right personnel, develop best practices that are unique to our clients, and bridge the latest technologies to ensure the best outcomes.

Our success in one of the most complex specialties to bill for, anesthesiology, has enabled us to extend our services to Office and Hospital Based Practices, as well as Ambulatory Surgery Centers (ASCs), while remaining the premier Anesthesia billing company in the United States.
