Two years later, following a significant corporate restructure, he was appointed to the Board as Finance Director, a position he still holds. His previous career included time spent in auditing, banking, finance, tax, law, and manufacturing, but none have proved as challenging or as rewarding as his time with Lancet Laboratories. He is honoured and grateful to have been allowed to serve the Practice in this way.
