Executive Team

ROSANNA LEIDL, RN, BSN - Founder and President

Ms. Leidl has over 28 years of broad-based experience in working with major health insurers and regulators on quality of care issues, utilization management and regulatory compliance. She has been integrally involved in insurance and health plan surveys that have re-shaped the policies that regulate managed care in California and across the nation.


Ms. Leidl founded Managed Health Unlimited, Inc. in 1995 and assembled a multidisciplinary team of consultants with expertise in quality assurance, systems evaluation and managed care best practices. Ms. Leidl and the MHU team have conducted a wide variety of surveys and investigations on behalf of the Center of Medicaid and Medicare Services (CMS), California Department of Managed Health Care (DMHC) and California Department of Justice aimed at investigating key health care issues, protecting healthcare consumers and ensuring access to quality care. As a hands-on president, Ms. Leidl actively participates in surveys as a surveyor, and is uniquely qualified for this role. She co-authored eight definitive Technical Assistance Guides that delineate the criteria and processes for surveys and the development of project-specific audit tools. These guides have become the standards for industry reviews such as Routine Medical Surveys of Full Service Plans; the Assessment of Health Plan Management of Claims; Routine Medical Surveys of Dental Plans, Behavioral Health Plans, and Employee Assistance Programs; the Focused Review of Parity Act Compliance of Full Service Plans; the Review of Evidence of Coverage & Disclosure Forms and of Provider Contracts; and Post Claims Underwriting, Non-Routine Surveys.

Her prior experience includes consulting for the Office of Managed Care of the Health Care Financing Administration (HCFA, now CMS) as a reviewer during HCFA’s investigative and monitoring activities at federally-contracted HMOs across the nation.  In addition, she is a former NCQA-certified HEDIS compliance auditor, and participated in HEDIS audits of health plans conducted by KPMG, a former licensed HEDIS auditing firm.

In addition to her project work with DHMC, Ms. Leidl has participated in a national study, the Community Quality Index, conducted by the Rand Corporation, and served as project manager and technical advisor in the development of a managed care software package that integrated medical and social benefits for a California Social HMO. 

Prior to founding MHU, Ms. Leidl worked for AETNA, Blue Shield of California and SCAN where she gained expertise in managed care. She is a Diplomate of the American Board of Quality Assurance and Utilization Review Physicians, Inc., and a certified case manager. She earned her B.S. in nursing from the University of Santo Tomas in the Philippines and completed management courses at the University of California, Los Angeles.
