Kelly brings a background in 'designing for digital’ to Drp, and has worked with brands such as Toys R Us, Aston Martin and Premier Inn.
He has been brought on board to meet the agency's client demands around improving the user experience.
Johnson will be responsible for building on the agency’s reputation in the industry, and sits within its PR and marketing team.
Drp has also promoted long-standing employee Suzie Blundell from project manager to account manager. She will be working on the EE account, which the agency won earlier in the year.
Dale Parmenter, CEO at Drp said: "Drp has seen a rapid growth across all areas of the business in the last two years, and we plan to sustain this growth during 2016.
"We are hiring the brightest, most determined individuals, who have the ‘anything is possible’ mind-set innate in their work ethic, which drp maintains."
Drp announced the hire of Andrew Grierson as project manager last month.
