“I have been working with Tony and the team at SYS Group for the past five years and have found them to be highly pro-active and innovative over that time. They also have an extremely efficient back office support team which is attentive to all administrative details. SYS has helped develop and guide our strategy on a wide range of pensions and investments and has been particularly imaginative in working with us to achieve above average returns in these challenging times while at the same time cognisant of the risk environment. Tony and the team are always available for support and advice and operate a flexible model that seeks to present clients with the most current and relevant picture of the investment landscape.”
