Leadership Team A Veteran Healthcare IT Leadership Team

Extension Healthcare shares its history with many successful technology companies in that it was initially conceived and brought to bear by a small group of visionaries with an idea and a will to see it through. Together, they turned their idea into the design of the Engage platform, and a fast-growing company that now employs over 160 Associates across the United States.

Extension is proud to boast about its veteran healthcare IT leadership team, which understands the clinical issues that plague hospitals today. Extension is committed to providing the most innovative alarm management solutions that help clinicians retain some autonomy and control over their time while continuing to meet the hospital-wide alarm safety and communication objectives that are important to department managers.
