Mr Drewitt, who is a wheelchair user, is a student in Gloucester and is working with Marketing Gloucester to produce a new tourism guide for the city.
The guide will be specifically targeted to give advice on the best attractions in Gloucester for those with disabilities.
Mr Drewitt said: “It is not easy for me to get around personally.
“I have a passion for Gloucester and want to help promote the city, its tourist attractions and leisure facilities.”
The student approached Marketing Gloucester with the idea of producing a guide that was practical.
The guide will be written from the viewpoint of someone with limited mobility and other impairments such as limited vision.
Mr Drewitt added: “I would like to help make a change that will benefit others like me.”
The guide is expected to help both tourists and tourist attractions on how they can improve their visitor experience for disabled people.
Christian Drewitt believes that Gloucester needs to improve across the city, saying: “If Gloucester was already accessible then I wouldn’t be writing this guide.
“However, places like the Quays are really good and accessible.”
The guide has been started and Mr Drewitt has been out assessing attractions in the city for over a month.
Jason Smith, Chief Executive at Marketing Gloucester, said: “We were very excited when Gloucestershire College approached us and asked if we would like to work with Christian on what he hope will be a model for other towns and cities.”
