Mayo joined TRO in April as a project director before being promoted as brand and business development director this month. Previously, Mayo was sponsorship and PR manager for Lebara and events manager at Honda UK.
Mayo’s main responsibilities will include marketing and PR, as well as supporting new business development.
Beaufort-Dysart rejoins TRO after a 12-month period client-side working across a number of key businesses for Ocubis, including the Dryland Business Members' Club.
She has previously worked for the agency for more than 10 years and will now be focusing on new business enquiries and supporting TRO’s marketing activity.
Michael Wyrley-Birch, managing director of TRO, said: "Luci and Sarah have worked together closely for many years while Sarah, in her role as partnerships and events manager for Honda, was a client of TRO. They have very complementary skills and we’re delighted to welcome them both into these new roles at such a significant time for the agency."
During this year, TRO opened offices in Singapore and New Delhi and have revealed plans to expand further internationally in 2014.
