Williams is impressed with the set up at Brisbane Road
Leyton Orient manager Geraint Williams and his assistant Kevin Nugent have signed new one-year contracts.
The 47-year-old has won nine of his 16 games in charge and ended relegation fears with three games remaining.
Williams told the club website: "We achieved the aim of staying in this division and we'll be working hard to build on that."
Nugent added: "We're confident we can build on the success of the last few months in 2009/10."
Williams took over as O's boss in February following the departure of previous manager Martin Ling.
The Welshman had previously led Colchester to their highest ever finish of 10th in the Championship in 2006/07.
He said: "I'm thoroughly impressed with what I've seen at Leyton Orient and I'm delighted to renew my contract."
Nugent is a former O's player who was promoted from youth team manager to become Williams's assistant.
He added: "I really enjoyed my time with the youth team and I will still be involved with the development of our young players.
"But the main focus is on the work with the first-team now and we're looking forward to the challenge of next season."
O's chairman Barry Hearn said: "We're delighted Geraint and Kevin have agreed to stay with us and continue the good work they've started over recent months. The results have been excellent at a difficult time."
