    CST is founded by Jeffery Prough on a mission that remains in effect today: empower older adults, people with disabilities and those battling chronic illness to live independently, with dignity. With a clear vision to deliver on this mission through healthcare B2G and B2B partnerships, CST formalizes a managed care strategy.

  •  - 2007

    CST earns the designation, which remains in effect today, of Preferred Personal Emergency Response System (PERS) Vendor for the National Association of Area Agencies on Aging (n4a). During this time, CST begins the process to obtain formal Medicaid licensure with an official NPI ID and multiple taxonomies.

  •  - 2008

    CST launches a new monitoring solution designed for senior living properties, which currently serves more than 30,000 residents. CST also begins a three-year grant project for in-home vital sign monitoring with the Alaska Federal Health Partnership, which ultimately generates a 15x ROI.
