Paskin assumes full responsibility for the creative department and creative work, working with Towers who will lead design and art direction.
Towers joined the agency in March, while Paskin joined in 2012. The changes follow the news that the managing partner Mark Lund is leaving Now to join McCann Worldgroup as its UK group chief executive.
Paskin started his career at HHCL, and has worked at Leagas Delaney, Lowe and M&C Saatchi. He has won awards for his work on Pepe Jeans, Stella Artois, and Adidas and was creator of the "Star Wars" campaign for Currys/PC World.
Towers was a designer at Fallon’s design shop, Duffy, and then was the head of design at TBWA and Lowe. He won a D&AD pencil for his work on Peeterman Artois and picked up Creative Circle Gold for Yell in 2012.
John Townshend, the founder and creative partner at Now, said: "Steve is a fantastic big thinker, has an immaculate pedigree and is superb at bringing out the best work in people.
"And Dave is simply one of the best design talents in the country. It is as strong a creative leadership team in ideas and craft as anywhere I know."
Townshend and his co-founders Melissa Robertson and Kate Waters, have recently promoted a number of people to the agency’s board, including the planning director, Ben Stewart, the head of client service, Laura Chamberlain, and the marketing director, Melanie Portelli.
Stewart is a former board planning director at Abbott Mead Vickers BBDO and BBC marketer, Chamberlain previously worked at DLKW Lowe as head of client service and Portelli’s past experience includes time as the head of new business at Saatchi & Saatchi.
