The Greek symbol, sigma, is used to denote a sum in mathematics. For us, it is emblematic of our approach to giving what we believe is wise advice by “summing up” a variety of wide-ranging and often confounding inputs and factors to reach a conclusion. We use a combination of highly analytical thinking, combined with significant experience and strong intuition to find the non-obvious answers. We pride ourselves on our ability to “see around corners”.
