Des Allen will step down from his position as CEO of Tennis Ireland on 5 August following 20 years of service.
The organisation has already begun the process for a new CEO, with an appointment expected to be made in August.
Commenting on his forthcoming departure, Allen said: “I will have completed 20 years of service with Tennis Ireland in early August and I feel this is the right time to move on.
Tennis has been my passion for most of my life and I feel privileged to have been able to work in the sport at this level for this period.
“I am pleased to be leaving Tennis Ireland at a time when the numbers playing our sport are growing again.
“Equally, our National Academy is now producing a generation of players capable of competing in Grand Slam tennis.
“I am leaving Tennis Ireland as an organisation which is very solid in terms of financial performance and governance and I would like to wish the incoming CEO every success. For me it’s time to begin the third act!”
David Barber, Chairman of the Board of Tennis Ireland, added: “I would like to thank Des Allen for his long and distinguished service to Tennis Ireland.
“He has been a great champion for Tennis in Ireland and I know everyone would like to wish him the very best for the future.
“The Board is very grateful to him for everything he has contributed in the role over 20 years to the organisation and to the sport.”
