I specialise in managing portfolios on a discretionary basis for private individuals, trusts and charities. My role is to help clients fulfil their aspirations, both in the short and long term. All aspects of their financial situation are assessed alongside a willingness to tolerate risk in the pursuit of their aims before a tailored investment portfolio is constructed. As life evolves so may my client's needs and requirements.

An important part of my role is to view my client's wealth holistically and manage their investments to reflect their aspirations and level of risk, in order to deliver successful outcomes over the longer term.

As a Senior Investment Director, my priority is to help my clients achieve their financial goals. By understanding their individual circumstances and financial objectives, I help them to achieve this through discretionary managed portfolios. I mostly specialise in investment management, creating diversified portfolios that are bespoke to the individual client. However just as important is building lasting relationships with clients and professional advisers so that trust can be earned and maintained.
