Romans has been involved with the Alexander Devine Children's Hospice Service since 2008 after meeting parents John and Fiona Devine, who are the driving force behind the charity.
The couple from Dedworth lost their son Alexander, eight, to a rare brain tumour and have vowed to honour him by creating a caring environment in the county for other seriously ill children.
Peter Kavanagh, managing director of Romans professional services, said the company became aware of the charity after Fiona gave a 'powerful' presentation at its quarterly awards ceremony.
He added: "I defy anybody with a heart to hear a talk by Fiona without struggling to contain their emotions. Her passion is incredible.
"Everybody bought into it and as a company we have done lots of different events to raise money and people just really liked and identified with it."
Since then, Romans has organised a number of events to help raise funds for the charity, including sponsored bike rides, half marathons, swimming and even baths full of baked beans.
The latest venture is a cook book compiled with recipes chosen by Romans employees.
Mr Kavanagh said: "We have done our own cook book which has our own recipes which we printed and sold within the company.
"I think it's a brilliant idea. We have 1,000 copies up for sale and we hope to sell as many as possible."
The Alexander Devine Children's Hospice Service was Romans' chosen charity for 2012/13, and will remain as its chosen charity until the £5million hospice is built at Snowball Hill in Woodlands Park, Maidenhead.
Romans, the winner of The Times South East Estate Agency of the Year 2013 Gold Award, will be meeting with the charity this month to talk about new fundraising initiatives, and will pledge to match the amount raised by its employees.
"There are very few people in our company who haven't got involved with fundraising," said Mr Kavanagh.
"The big thing is when you talk to people they really want to get involved and I think that's why we keep going."
The mission to raise £5million towards building the hospice is being backed by the Express and its sister papers, the Maidenhead, Burnham and Twyford Advertisers, through the Together We Can Build It campaign.
