Alongside her impressive experience, Mary has an infectious energy and warmth that makes people want to work with her – and for our team and clients alike, that's every bit as important to us as what's on her CV. As we continue to grow, we're investing in people who not only bring expertise, but who embody the collaborative, ambitious and people-first culture we've worked hard to build. Mary is a brilliant fit for Sense, and we're excited to see the impact she'll have on our clients, our team and the next chapter of the business"
