About

For over 20 years I have specialised in providing pre & post-retirement planning. I assist my clients in planning for the retirement they aspire to, providing peace of mind regarding their financial affairs and addressing concerns about transitioning from work to relying on savings and pensions for future financial security. An important part of this planning involves analysing future cashflow to understand income and expenditure during retirement. Additionally, when discussing investment strategies for growth or income, I address potential investment losses to help clients manage apprehension during market volatility and stay on track with their plans. And of course, a significant part of this work involves tax planning, aiming to create efficiencies using a range of products that suit clients' specific needs and objectives. I'm very passionate about my work as it is a privilege to play such an important role in helping them plan and have peace of mind around their retirement. Advice on tax planning is not regulated by the Financial Conduct Authority. Please note Argentis rebranded to Shackleton on the 1st September. Any references to Argentis in client reviews prior to 1st September, relate to the company's previous brand.
