On working at FSG

“I’ve been fortunate to watch FSG grow over the years and nearly triple in size from the time I started here. It has offered me so many opportunities to learn how to adapt to fast growth, and how to build out our team and our systems in response. I had wanted to begin the next phase of my career with an organization that has a genuine mission to generate positive changes in the world. I wanted to be challenged by a dedicated firm with a mission similar to my own values. FSG has enabled me to do all of that. I feel very lucky to be part of such a dynamic and growing company, surrounded by so many motivated and inspiring colleagues!”
