Evans and coach James Hird made emotional speeches on Monday night at the Bombers' season launch, thanking the players and fans for their support.
Evans has also announced an independent review of the club as a result of the crisis.
The anti-doping investigation is likely to take months, meaning it will hang over the Bombers for much of the season.
"I understand the way you look at me tonight, looking for reassurance our beautiful place will be okay," Evans said.
"I promise you that it will be.
"The hurt of the past few weeks is still raw, but it is this room that gives me strength - given how you all have stood behind the club in its hour of need.
"We will get through this and we will be a better, stronger organisation."
Evans also apologised for the circumstances that led to the crisis.
"Mistakes have been made and I sincerely apologise that they have occurred," he said.
"We will get to the bottom of what happened, we will make sure those mistakes never happen again.
"While we know some things, there is so much we don't know, and we're continuing to piece together a long and complicated jigsaw puzzle.
"I commit to you that we are making progress."
Hird said it had been humbling to coach the team in the past few weeks, adding the players had stayed focused and disciplined.
"My family and this football club means everything to me and I will do everything that is in my power to get the club through this difficult time," he said.
"That means being the best coach I can be to this wonderful team of young men who wear our colours so proudly."
