Our team

Everyone says it, but in our case it’s true: our team is the secret to our success. Each of our employees is amazing in their own right, but together they are what makes Rostrum such a fun and rewarding place to work.  The Rostrum team is a tight-knit, talented group with a shared vision of delivering consistently great results for our clients, as well as ensuring the agency is a fun, inclusive, challenging place to work and develop a rewarding career.

We’re very proud of the team we’ve built – there’s more than thirty of us now but it still feels like it did when there were just a few of us.  Rostrum has always been an agency defined by bringing together talented people with a shared vision and passion for helping us to be the best we can be for our clients.  But that doesn’t mean Rostrum is a cookie-cutter agency.  All of our employees are unique individuals who are united by a set of five core values that apply to everything we do within the agency.
