About Us
We are an innovative company and have been at the forefront of physician support services to aid physicians in navigating the healthcare marketplace. Using data analysis obtained through our clinical integration program we assist our physicians in understanding the concepts of cost, utilization and quality in healthcare.
PPN is committed to the preservation of physician independence in the age of healthcare reform. As a PPN physician, you maintain your autonomy in running your own practice, but have access to the enhancing resources of a larger group of like-minded practitioners.
