The move comes just months after Roger Draper was appointed the LTA’s new chief executive in February.
Performance director David Felgate, tennis operations director Rebecca Miskin and finance director Paul Keen have all now left the LTA.
An interim leadership team has been appointed in the short term, with more permanent positions made in due course.
Draper said: “All three have worked extremely hard to support British tennis and I wish them all the best in their next ventures.
“An interim LTA leadership team has been appointed to ensure that we move forward with purpose whilst a new structure is created and a new team recruited.”
The UK’s Lawn Tennis Association has lost three of its senior management team as part of an on-going major restructuring programme.
