A former member of the Parachute Regiment, Greenslade-Jones represented Pontypridd, Gloucester, London Scottish and London Welsh during his playing days, as well as the Wales A team.
He was one of seven candidates interviewed for the head coach role at Bracknell and brings with him player/forwards coach Stuart Silvester, who is currently serving as Regimental Seargant Major in the British Army.
Greenslade-Jones, pictured right, has previous experience coaching with London Scottish, Basingstoke and Gloucester and also works as a community development officer for the Rugby Football Union.
His first port of call at Bracknell will be to get them back into National Three South East after they suffered a surprise relegation last year.
But along with pushing the first team to National Three and above, Greenslade-Jones, 37, wants to ensure the club functions better than it has done recently.
"The main aim of course is to get the first team promoted next season and then in three years to get them up into National League Two," he told the News.
"But we also have a one club vision and that means bringing everything at the club together and aligning all the teams from the minis all the way up. The process will focus on player and coach development throughout the club with a transparency from first, second and third teams to create a successful winning environment at all levels through the one club vision."
Chairman of rugby elect Martin Radford echoed Greenslade-Jones' comments and added that the new coach will be working on strengthening all aspects of the club.
"In recent months we have been trying to change a few things such as the ethos of the club," he said. "The appointment fits in well with our one club ethos. We are trying to be ambitious and get the first team back into level five and then up into level four, but we also want to make sure that growth is sustainable so committing to all levels, from juniors to seniors.
"We want to develop a strong youth level and a home grown side with a few imports and Rory will not just be developing the first team he will be involved in other areas too.
"He's a very experienced player and a great up-and-coming coach who has got the coaching skills. One thing that was important was his contacts in the game, he has a lot and he's young and ambitious."
Greenslade-Jones took a break from playing rugby last year to work at London Wasps' academy and he does not intend to play for Bracknell unless required.
He will meet with the players early on in June to lay out his plans and hopes they will approve the direction the club is going in.
"We will bring the players together to explain the vision and the process so we can all move forward in the right direction and get Bracknell RFC back in the national leagues and sustain it for many years to come," he commented.
Carson Russell, who joined Bracknell from Barnes late last year, will not be at the club next season.
