Mark qualified as a pharmacist in 1984 and established his first pharmacy business in 1986. He was a founding Director of Hulmes Chemist ltd in North Staffordshire until this business was sold in 2005.
Mark was one of the first pharmaceutical advisers in the country to be trained under IMPACT project at Keele University, which resulted in Mark being recruited to Cannock Chase PCT as a pharmaceutical adviser. He was then appointed to Head of Medicines Management for South Staffordshire following the merger of the four smaller PCTs.
In 2012 Mark took up the role of Strategic lead for Medicines & Decision Support, which included a remit for managing individual funding requests and clinical prioritisation on behalf of the four South Staffs CCGs. Mark then moved into general NHS management as the Interim Chief Operating officer in South East Staffordshire & Seisdon Peninsula, before being appointed as Director of Commissioning for the three South Staffs CCGs.
