Ben Williams, 24, is one of 14 volunteers on the books of the corporation-come-charity that has helped about 2700 people since being launched by Lynn Field two years ago.

A friend introduced Mr Williams to his current mentor and role model after he suffered a back injury at work and experienced anxiety and depression.

"It's really hard to go from working 38 hours a week and overtime to nothing," he said.

Free courses offered by the corporation helped put his life back on track, to the point where he jumped at Ms Field's request to lend a hand.

Mr Williams, who has reduced mobility, has signed on for 20 hours a week as a "support worker" with many and varied duties.

They include supporting men who visit the corporation and people called before the courts, helping to run anger management courses and heading up the formation of Dubbo's first Narcotics Anonymous group.

"I've had a pretty blessed life," Mr Williams told the Daily Liberal.

"Apart from the injury, I've had the best job you could get, the best family and upbringing and a really sort of privileged lifestyle.

"It seems to me it's time to give back and earn what I got at the start."

His blessings include Ms Field who is ecstatic to have enlisted a right-hand man.

"Getting people to commit to a hefty amount of time of volunteering is difficult," she said.

Mr Williams calls Ms Field "superhuman" in recognition of her unpaid care and training of thousands of clients.

"I don't think she realises what she has done for me and what she is doing for our community," he said.

The corporation runs programs in Dubbo, Narromine, Coonamble, Wellington and "wherever we are needed", Ms Field reports.

They tackle personal and community problems including uncontrolled anger, substance abuse and domestic violence.

On the horizon is a new course called Uncut Opals targeting "young men who see domestic violence in the home and grow up and do it to their partners".

Another program called Gems teaches children about "respect, rights and responsibilities".

Nguumambiny, a Wiradjuri word meaning "a trust for help", runs six days a week and does not charge fees for its services.

"It provides services to people who can't or won't access them elsewhere," Ms Field said.

She freely admits that Mr Williams will be key in helping manage a growing workload.

He is keen for people in need to keep coming through the corporation's door.

"I just would really like to encourage anybody who is going through a hard time to come down and have a chat with us," Mr Williams said.

"People shouldn't feel embarrassed or any sort of shame factor because everyone goes through hard times.

"As much as you might feel it, you are not alone."

Donations to the corporation are tax deductible.

Nguumambiny Indigenous Corporation has previously received a Dubbo RSL Club grant for in-demand anger management courses.
