Cathy qualified from Guy's Hospital in 1994. She spent the next 12 years working as the hygienist at the US Navy base in RAF West Ruislip which provided her with excellent opportunities to further her knowledge and clinical skills. In September 2006, the base closed down and she moved onto work at a dental practice in Ruislip. She now divides her working week between 3 dental practices.

She earned a Certificate in Oral Health Education from the College of North East London, 1993, and attended the Course in Extended Duties at The Kings Dental Institute, 2003. She is also an associate member of British Society of Periodontology.

Cathy is married with 2 daughters.
