JOIN THE SULLIVAN TEAM
One of the reasons I joined Sullivan was because I knew I would be able to learn and grow in my career. My manager has supported me in finding personal development goals to further my career and continue to gain new skills. I have already been able to lead new projects on my own and take the lead on different initiatives.
