The office will act as a regional hub for East African operations. It will be staffed initially by a team of 12, with Kenyan nationals making up 70 per cent of the team.
The Nairobi office will co-ordinate with Grayling’s consultancy teams in Abu Dhabi, Doha, Dubai, Istanbul and Muscat. Loretta Ahmed, Grayling’s chief executive for the Middle East and Africa, will oversee the operation.
The expansion into East Africa comes as clients are increasingly focusing on the region for business, according to Paul Taaffe, chief executive of Grayling's parent group Huntsworth.
"Leading global businesses in infrastructure, financial services, telecoms, travel and hospitality are extending their reach into the continent and require agile, local communications teams who operate to international standards," he said.
"With a highly talented, Nairobi-based team and the experience of its global network, Grayling will be an important partner for local and international businesses throughout East Africa."
Grayling was appointed by the Kenyan Ministry of East African Affairs, Commerce and Tourism to help with "recovery and revival" and bring "inward investment" to the nation.
The country has been plagued by large-scale terrorist attacks by Al-Shabaab in recent times. The latest took place at Garissa University on 2 April, where 148 people were killed.
The UK Foreign Office currently advises against all but essential travel to a large portion of eastern Kenya.
