Paul Lambert welcomed new coaches Scott Marshall, Michael Watts and Chris Lorkin and stated: "I have total trust in them."
Marshall [pictured] has come in as first team coach while Watts and Lorkin will work on the fitness of the players.
Lambert spoke of his delight at adding the trio to his backroom staff, which already includes Ian Culverhouse and Gary Karsa.
Former Arsenal defender Marshall met Lambert when he was part of Wycombe's academy coaching staff with the manager in charge of the Adams Park outfit from 2006 to 2008.
Having moved to former club Brentford to manage the U18 team in 2007, he joined Chelsea's academy staff in 2008.
Spells with QPR and the Arsenal Soccer School in Oman followed before he was appointed Professional Development Coach at Norwich City in 2012, in charge of the club's U21 team.
Watts began his career as a strength and conditioning coach at Sheffield United, spending three years at Bramall Lane before moving to China.
After two years there he joined Norwich City in 2010 as the Head of Performance and Strength and Conditioning, managing the physical programme for the first team at Carrow Road.
Lorkin also joined Norwich City in 2010 as the lead Strength and Conditioning Coach for the academy, spending two seasons working with their youth teams from U9 to U18 level, as well as assisting with the reserves and first team.
Villa boss Lambert is strong in his faith that all three will enhance the set-up at Bodymoor Heath.
He said: "I worked with Michael and Chris at Norwich and I know exactly what we are getting - two good guys who put the work in. I trust them to do it.
"The two of them will bounce off each other with the rest of the staff.
"They are two good guys who will be good at their jobs.
"I knew Scotty from Wycombe. Scott helped the young ones at Wycombe.
"He has a really good way about him and really good mannerisms aswell.
"He is a good coach and he will enhance the first team."
