About Us

Ian’s commercial career started in the telecommunications industry. In the late 80s he established Sinian Communications Ltd which provided IT and Telecommunications services to UK based multinational companies including UBS, Racal and Statoil. Following 25 years at the helm of Sinian he stepped down in order to pursue his passion for sailing.

In 2002 Ian was coaxed out of retirement by Bosch to run their UK telecom division, called Tenovis. Among other things, this work involved combining the large-scale telecoms and Data systems for Network Rail. In parallel to this Ian also became a Project Manager for the implementation of the UK Government’s Patient Power project.

In 2017 Healthier Lives Ltd was formed. A forerunner to PRS, it was set up by many of the current team including Ian and Dr Rob McCullough. Healthier Lives has developed a system for 365 day vertical farming using water cooled LED lights.
