I need a spreadsheet of dental practices - private and mixed (NHS and Private) not clinics that are fully NHS in Greater London also including all of Essex
I would like the spreadsheet to be divided into areas in London

- Practice location address
- Practice email address
- Practice Manage name if available
- Practice phone number
- Practice owner name if available

- Whether the practice has any specialists and if so what specialists
