Both Lyddy and Roddy will be responsible for the agency’s financial clients.
Lyddy joins the agency from Dyson, where she was account director, GB&I marketing, with Roddy joining from GovNet Communications as head of event management.
On her appointment, Lyddy said: "The DRP Group is going from strength to strength, and so this is a very exciting time to join them. I’m really looking forward to working with the team and to be a part of what lies ahead."
Roddy added: "I've worked with financial clients before but this will be a new role for me. The biggest challenge will be to deliver added value to the agency and to get under the skin of what the client wants.
"The aim is to form an extension of their team and to be as proactive as possible."
