"(Our)Volunteers could see the email statistics of member engagement, which encouraged those who were slow to be convinced of the benefits of centralisation."

"On big projects, it’s really, really hard to find someone who does what they do, that mix of flexibility and reliability is rare."

How we centralised regional member events (without falling out with our Volunteers)


  • The CIEH was founded in the 1840 and is the professional voice for environmental health.
  • Provides information and policy advice to government, environmental and public health practitioners.


  • We had a problem with our CRM system
  • We brought Trillium in to look at our CRM database. They also carried out integration projects with our website, followed by a CRM upgrade.
  • They helped us introduce an event management system.

Our events booking system was not working

  • We run over 150 events annually, and our regional volunteers run their own events. However, because there was no common event booking system, we ran into issues.
  • There was not enough central coordination of events.
  • Our head office often didn’t know what was happening, and;
  • Diary clashes around head office and regional events.
  • Members called into our head office to ask about locally organised events, and the team were unaware.
  • The regions couldn’t tell who were members when booking events.
  • No website integration.


  • Trillium introduced our new event management system that integrated with our CRM and website.


  • Single source of CIEH event information.
  • Members can book events online, 24/7.
  • Members attending more than one event per quarter increased.

The Trillium difference?

  • It's a partnership.
  • I can chat with them and rely on them to say 'look, we'd love this piece of work, but we don't recommend it for the following reasons…'
