And that's not all, with many others throughout health sector, including the Cancer Society and Cranford Hospice.
Mason said while many of the "selfless individuals" were retired, others had part-time jobs.
Meet and greet service volunteer Maureen Grapes has been one for the past three years - but it isn't the first time she has volunteered.
As a retired nurse she gives up her time twice a week, helping people find their way to various wards or clinics, and assisting teams and patients ready for discharge in the Transit Lounge to ensure a smooth and seamless transition between hospital and home.
The team, who work in shifts between 9am and 3pm Monday to Friday, also arrange for luggage transfers, wheelchairs, refreshments, and parking for family members directly outside the front entrance to ensure ease of transition to vehicles.
Over the course of a year, more than 1000 trips are made between the volunteer meet and greet front help desk and the transit lounge.
"I think I get more out of being a volunteer than what I give," she said.
While it's not always possible, Grapes tries to speak to every person who enters the front door.
"I get to see everyone from newborn babies to people in their late 90s - a cross-section of the community."
As for when she plans to stop giving - it might be a while yet. "I will only stop when I can't push the wheelchairs."
On Monday, they had a celebratory lunch for the volunteers.
"We heard from many that they volunteer to give back to the community," Mason said. "They also get a lot of joy being a volunteer and being able to help."
