Sue Johnson

Sue sits front of house at Leon and Company, and is the first person everybody meets on arrival. She takes on the busy role of secretary, admin and PA to our team, but she is always ready to warmly greet our clients with a friendly smile and coffee!
Sue was previously PA to the Head of a busy primary school. She brings these skills with her, supporting the team with her organisational skill base, bringing a cheery air to the office – and keeps everything ticking along very nicely. Sue manages communications with our clients, along with overseeing online filings to Companies House, and ensuring that clients hand in their records in a timely manner – and yes, Sue is known to chase our clients from time to time!

Using her experience of working at a primary school for many years, Sue maintains the efficiency and smooth running of our offices – but if we misbehave, its detention and one hundred lines after work.
