As of February 9th, 2022 Mark Gullett has joined Calvert IHS to partner for the future, guaranteeing that when the time comes one day for Joe to retire, Calvert IHS carries on with no diminishment of service!  In fact, Mark brings skills in management and in enhanced detailed knowledge of the installation and wiring of mechanical and electrified hardware and the installation of doors and frames, which should make for even better specifications and inspections.  A gradual transition is planned over a period of years as Mark, an invested full partner, earns the appropriate specification writing certifications.
