Volunteer Fundraiser

My volunteering role with the HMF began in 2020. I was sitting at home undergoing treatment for breast cancer and thought it would be an opportunity to do something positive and keep my mind busy! So far I have enjoyed assisting at events, seeking out donations of prizes for raffles and coming up with ideas for fundraising, such as a virtual balloon race. It is exciting to be a part of this growing charity, the team always make me feel appreciated and valued, which I can say, hand on heart made a huge difference to my mental state during my treatment.
