I've now left Severn Trent after 34 years. Much of this was spent working alongside the OFWATregulated business - in particular in financial services as the FCA Approved Person, establishing and then running the property searches business and heading up the team that runs Severn TrentConnect, a New Appointment Company in Aldershot.

As a collaborative and consultative senior manager I have experience in implementing major changes including setting up new businesses, strategic planning, stakeholder engagement and building commercial relationships.

I am known for giving honest feedback on the feasibility of project ideas and identifying real business opportunities.
I bring my extensive experience in working with regulatory and government organizations to solve problems and policy issues including advising on the drafting of legislation.

I was a founding board member of Property Code Compliance Board which was setup to create a regulatory framework to enable businesses to provide quality assurance for their products (data reports for property professionals). I have previously been an active Board member of the Council of Property Search Organisations (CoPSO).
