Gill qualified in 1982 and, after working as an associate in Harley Street, set up Millman and Harris Dental Practice in 1987. The practice operated from premises in London SE1 and offered all aspects of dental care.

In 2006 Gill sold her practice but remained as an associate to provide continuity of care to her patient base.

In December 2008 she moved back to Harley Street, into temporary accommodation, until her new premises were ready in the New Year.

In March 2009 she became the principal of The Cavendish Dental Clinic.
The Cavendish Dental Clinic provides a first class service in a smart, friendly and welcoming environment.

Cavendish Dental Clinic relocated from 28 Harley Place to 7 South Molton Street, W1K 5QG
