Purvis has previously worked at Universal World Events, now Ashfield Meetings and Events, and packaging specialist Avery Dennison.
In her new role, Purvis will be responsible for managing events from booking through to delivery, as well as developing the services offered to business groups across the portfolio of venues.
This follows Imago's appointment of Richard Money as senior business development manager last week.
Purvis said: "I’m looking forward to being part of imago’s continuing success story through the development of its events service offering and bringing on new business in its target markets."
Emma Boynton, head of sales and marketing at Imago added: "Naomi brings with her a wealth of experience and makes a great addition to our team, particularly having worked in the pharmaceutical sector – a key target market for Imago."
