After a seven-year career as an audit/tax CPA at Price Waterhouse Coopers, Shannon spent 19 years at Russell Investments building their financial footprint around the world. She worked in both Japan and Australia opening their asset management business and growing their mutual fund distribution through the private banking arms of Bank of Tokyo Mitsubishi, and ANZ Bank, respectively.

She was also a member of the Russell Index Executive team and was responsible for the global operations that doubled gross revenue and tripled net profit in 6 years, expanded their presence across 4 continents, and ultimately contributed to selling the private firm to the London Stock Exchange for $2.7 billion in late 2014. She then integrated the two firm’s UK and US operations before she left to start her own business in 2016 which was partnered exclusively on the global vertical within the legal cannabis industry. In this capacity, Shannon served as the Chief Strategy Officer for two companies; a cannabis banking compliance software firm and a US cannabis retail firm, and also worked for Tilray, a publicly-traded Canadian cannabis company, helping with their global market entry strategy.

Since Dec 2019, she has served as the CEO of Evergreen Market, a multi-state retail privately-held cannabis company that generates over $30 million in annualized revenue. Along with being on the WACA Board of Trustees, Shannon also serves on the National Cannabis Industry Association (NCIA) Retail Committee and is a member of the global group, Women Empowered In Cannabis (WEIC).
