"I'm not anxious, we just want the truth," he said on Friday.
"David Evans wants the truth, the football club wants the truth, the supporters want the truth and that's what we're after. And I believe that once that comes out, we'll be able to get on and play football."
Essendon chairman David Evans this week announced that the Bombers had commissioned the review, which will be headed by former Telstra chief executive Dr Ziggy Switkowski.
With the review set to include all levels of governance at the club, Hird said that he was hopeful it would find answers as the Australian Sports Anti-Doping Authority investigation into supplement use continues.
After senior assistant coach Mark Thompson this week admitted to feeling "embarrassed" as the investigation unfolds, Hird said his players had embraced the situation and were approaching it the right way.
"Our footy club is going to fight. We're going to fight to prove where we're at and we're not walking around with our heads bowed. We're walking around proud of our footy club," he said.
He has not been notified of a timeframe for the review, but said he will be involved as much as required.
Hird, who is entering his third year as coach of the club, reiterated his focus remained on coaching the Bombers and improving the football team.
"If we have to be distracted during the week we will be and we'll go through this review process properly to get the truth for our supporters," Hird said.
"I think our supporters deserve that, they want that, and as I've said a number of times, they are fantastic supporters. They've given us amazing support over the last three weeks and we owe them that."
Essendon trained on Friday morning in front of a large number of fans at the Wangaratta Showgrounds, where they will meet Richmond on Saturday evening.
The Bombers have picked close to a full-strength side, with Hird saying only three players were unavailable through injury.
