I won't bore you with the stock-standard list of training that every second editor has completed. There's a common path we all take to reach a common goal. That's the reality of the profession.
What I will do though, is wow you with my impeccable customer service (thanks to working in retail, as a consultant, and perched nicely at the front desk of a library where I became fluent in 'shushing' students), and natural empathy.
Two invaluable skills that allow me to understand my client, their audience, the individual requirements for each project, and in the process, become a kick-ass colleague and go-to for all of their copy enhancing needs!
