Leadership
Impact Health’s leadership expertise is rooted in population health management, laboratory medicine, finance, and operations. We have achieved success for over 30 years and have laid the groundwork for what has become one of the nation’s premier biometric screening and wellness companies.
The executive leadership team founded a national cost-effective biometric/flu voucher program offering that will be available at local retail pharmacies throughout the United States. We are a company that understands and responds to the marketplace. At Impact Health, our clients find these to be invaluable attributes when selecting and partnering with a biometric screening company.
