Mary Hardenbergh, CPMSM, President and Founder of The Hardenbergh Group and Hardenbergh Interim Staffing Group, has enjoyed contributing to the medical staff and credentialing services industry since 1986. Mary was a Corporate Director of Medical Affairs when she successfully established one of the first centralized credentialing organizations and single medical staff structures in the country for a major multi-entity health system in 1988. This led to national attention and the development of a sought-after healthcare consulting business. Mary discovered a need in the staffing field while consulting in hospital medical staff departments that could not be overlooked. The demand for highly-skilled temporary medical staff professionals (MSP) around the country was evident. She created a team of many of the best certified MSPs around the country to travel on-site to health systems, CVOs, credentialing departments, insurance plans, and other healthcare entities to step in and provide their expertise seamlessly, efficiently, and needing no training. Many of the original MSP team is still lending their expertise to Hardenbergh 20+ years later, in addition to the hundreds more that have joined the Hardenbergh pool of phenomenal medical services professionals.
Hardenbergh continues to be the leader in the staffing industry for medical staff services and credentialing with the help of these “best of the best” MSPs and a top-notch corporate team continuing the personalized-service approach with both contractors and clients, which has allowed Mary to change business gears and become active in other community and national projects.
The Hardenbergh Group is centered on building relationships and establishing a foundation of trust with our clients and workforce. Judy is a Medical Services Professional (MSP) with over 25 years of experience. She has worked with hospital administrators, medical staff leaders, and MSPs in hospitals, health systems, CVOs, health plans, medical groups, and networks across the United States. Her expertise in medical staff services, credentialing, and provider enrollment gives her deep understanding and insight to help support our clients’ needs and exceed their expectations. Her focus is on successfully placing the right MSP, or MSP team, on each project.
Prior to joining The Hardenbergh Group in 2008, Judy worked as an Independent MSP contractor for nearly nine years, completing a wide variety of assignments throughout the United States, which provided invaluable experience that she can share with our clients and contractors. While in the field, Judy worked on developing centralized credentialing operations for major health systems, restructuring medical staff services departments, promoting process improvement and credentialing initiatives, and helping clients obtain their goal of creating effective strategies to ensure compliance with regulatory mandates. Her experience as a MSP has also afforded her opportunities to help educate, train, coach, and mentor other MSPs.
