Annerley Reid, who works at Longmoor Lodge Care Home, is set to spend 12 weeks helping those in need in the Asian country.
She is raising funds for water sanitation equipment and other supplies ahead of the expedition, which begins in October 2018.
Annerley got the opportunity to volunteer in Nepal through sustainable development organisation Raleigh International.
She said: “Raleigh is giving me this amazing life experience, so I’ve agreed to help them raise some money for supplies whilst we are over there.
“I couldn’t be more grateful and so excited to finally do my bit in the world to make a difference and this is where it all starts.
“I think because I’ve been brought up with the residents at Longmoor Lodge, and now as a carer, I wanted to do more to help those in need.”
Annerley has been a care assistant at Longmoor Lodge Care Home, on Longmoor Lane, for five months but has been visiting the home since she was six years old.
Her mother, Marsha Reid, was also a carer at the home and regularly took her daughter to spend time with the residents.
One of those was Vera Haire, who still resides at the home and remembers visits from Annerley.
She said: “She used to sit on my bed and share my mints with her. Who would have thought she would then become a carer.
“I’ve enjoyed seeing her turn into a young lady. But today is a special day because Annerley has come and she told me she will be going to Nepal doing volunteer work with women and children for 12 weeks.”
Annerley will stay in touch with residents via Skype during her time in Nepal, when she will update them on what she has been doing and how the work is progressing.
Samantha Ely, home manager at Longmoor Lodge Care Home, said: “Annerley has only been working at the care home for five months, but it certainly feels a lot longer, as she has known some of the residents since she was a child.
“When she told us she was applying to volunteer in Nepal for three months we thought it was a brilliant idea and many of the residents are very interested in what she will be getting up to.
“We’re all looking forward to hearing how it’s going while she is over there and we wish her all the best.”
