About Célia

You are launching a digital initiative, rolling out a new platform, or trying to get your teams to actually adopt new ways of working — but communication and engagement are slipping through the cracks.

I help organizations cut through the noise by designing clear, human-centered communication strategies that drive real adoption and engagement.

With 2+ years at Sanofi (2,000+ employees, global regulatory environment), I have led end-to-end digital communication projects including SharePoint governance (10+ sites deployed), AI-driven engagement campaigns, change management programs, and cross-functional stakeholder coordination across time zones.

What I bring to your project:
  • Digital platform rollout & adoption (SharePoint, intranet, digital workplace)
  • Internal communication campaigns & change management
  • Employee engagement strategies & KPI tracking
  • Content creation & knowledge management
  • Cross-functional coordination in regulated environments

I work fully remote as i'm relocating from Canada to Europe, which means I am comfortable with international clients and multicultural environments.
