Our team of experts

In 1998 when Aisa was simply an idea between James and Clive, they did not imagine that what would start as a small two man operation based out of Wiltshire, would grow into an international company with offices in several countries. Their diverse backgrounds of psychologist and RAF pilot meant they have always looked at financial advice differently from those within the industry – to this day they continue to sit down together each year and review the next stage whilst Aisa continues to grow in both experience and offerings. However, they always want to stay loyal to their original concept, and what has made them successful – putting clients’ needs first and providing the best service possible from a client’s perspective.

With over 20 people involved in Aisa and their new network, OpesFidelio, they have a wealth of local and international knowledge and experience within the financial services industry including being qualified and regulated in multiple countries, the two prime locations being the UK and the USA.  

From early beginnings with the office being run from a small space on the kitchen table to offices around the world they have always ensured that they are surrounded by a highly professional and like minded team. Everyone within the Aisa team has a passion for ensuring that the client’s needs are the focal point of everything they do.

Our Chartered Financial Planners

What Chartered means and why we are Chartered

Chartered status is a gauge of competency and expertise in financial planning. To achieve and maintain our chartered financial planner status from the UK Chartered Insurance Institute (CII), we have to prove that we always work to the highest professional standards and advisers have to re-qualify each and every year, re-applying for the status.

We currently have 6 chartered financial planners either client facing or client supporting within Aisa or OpesFidelio (they are not all listed below). They operate within a larger team who also have expert knowledge in pensions and investments. Internationally we have several firms within Europe (Regulated separately in France and the Czech Republic, Branches in Ireland and Cyprus) and outside of Europe (the U.S.A., South Africa, and a marketing company in Hong Kong).

Aisa Group has 25+ nominations or awards between 2009-2019, winning a few along the way including 3 in 2018. We also have won individual awards as advisers such as SIPP planner of the year in 2017 (Money Management Award, part of the FT Group). We would like to think we are unique in the international financial marketplace. Each client facing financial planner has unique insights in their specialist areas which means you get the very best advice on a broad spectrum of investments.
