In 1991, Executive Director Patricia A. Rinzel, RN, BSN founded RINZEL & ASSOCIATES. The original business concept of detecting and solving billing errors and HealthCare Fraud & Abuse, reduced clients’ billing claims by $16 million in 2007. The evolution into Case Management Services to assure safe and cost effective outcomes for patients, launched our Case Management program for corporate and individual clients. Patricia’s experience as an Intensive Care Nurse, Clinical Nursing Instructor, Nurse Auditor for Medco and Vice President of Clinical Services for Aegis in California, brought Nursing/Medical/Business expertise to RINZEL & ASSOCIATES.
