Sarin, who looked after the operations of the PR consultancy's six offices in India, joined Good Relations, a Flagship Group company, as director (North) before being promoted to chief operating officer two years ago.
"There was loads to learn at Good Relations, but I have decided to take a step back and appraise myself," said Sarin.
"I will decide on whether to join the client-side or (another) consulting firm, or even consider other options."
During her tenure at Good Relations, Sarin was responsible for strategic alliances, business development, strategic input for clients, relationship management and the overall growth of the PR consultancy.
Among the clients Sarin handled while at Good Relations were MTV, AXN, Nickelodeon, GMR Group, Volvo, Lakme India Fashion Week and Bose Corporation.
Sarin, who has worked previous stints at Television Eighteen, Asia Business News and CNBC in the past, has nearly a decade-and-a-half of experience in the public relations industry.
