Coefficient was created in 2008 by Sarah Rossigneux. Whilst running her own restaurants, Sarah became aware of a gap in the market for expert affordable support. “Restaurant owners and managers are often so busy running their business that they don’t have time to spend on areas vital for growing the business such as marketing, operations & staff training,… This is where Coefficient comes in, providing you with those extra services exactly when you need them leaving you time to do what you do best… run the business”.

With 20 years experience in the hospitality industry, managing and establishing many successful restaurants, Sarah brings a wealth of experience to the business and has true passion for the service and food industry.
