"For volunteer work here, you need to get a police check, and by the time that happens, they've got a job and they're off.
"Volunteering is such a good thing to have on your CV, it becomes a real plus-point to employers."
Holmes says anyone can volunteer, even if they have little knowledge about horses.
"You can come in and watch a session and there's a training process as well. Once you know what you'd like to do, whether it be helping with the children's programmes or working with the horses then we can pick something.
"Some roles require a steady level of fitness so we check that with potential volunteers as well."
Even though there's a police check, that doesn't get in the way of volunteers being trained in the interim.
Holmes says they hold programmes from Tuesday to Friday for children and there are many positives of volunteering.
"It's always interesting to hear what the volunteers get out of it and why they do it in the first place.
"The reason why I became involved is because I've always worked with horses and I know how good they are for you, both physically and mentally.
"A lot of people like to come and work with the horses because they get a lot out of that. Others love to come and work with the children because it's wonderful to see them reaching their goals and sometimes making quite huge changes in their lives."
Holmes says volunteering can even lead to a new career path.
"Volunteers can go through a training process and gain a qualification, it is an option."
The organisation needs at least eight volunteers a day to assist with programmes, looking after the horses, administration, and keeping the grounds.
