"A huge thank you to OCAI online for managing and delivering our culture reports against the odds! Your support and insight were extremely valuable." - Johan de Goede, consultant, The Human Route

"The usefulness of the OCAI and the ease with which our clients can understand the data makes this a perfect instrument to use. The vendor is super-responsive. I love using this instrument and appreciate all the care we are given."

"I want to pass on my personal thanks for your speedy and highly professional analysis of my surveys."
Dr. Brian Armstrong, CoDirector of Unscheduled & Acute Care, Belfast Health & Social Care Trust

"My time is valuable, the OCAI frees-up the time it takes to administer and tabulate the individual surveys. I appreciate the quick set-up of the online assessment. Participants get immediate feedback on their own survey and this increases curiosity. The information OCAI provides will help these leaders make informed decisions."

Marcel & Marcella & team

Marcella BremerOCAI online is founded by Marcel Lamers MSc. and Marcella Bremer MScBA. We're consultants based in Europe and working worldwide. With the local OCAI-team and our partner consultants all over the world, we help you develop your workplace culture.Marcel Lamers

Before OCAI online, we founded "Kikker Groep" as a local consultancy for organizational development, culture, and change. When we researched the culture of the Dutch health care sector in 2008, the OCAI became the basis of our OD work. Since then, we've also added the Positive Culture Academy (online learning) and Leadership & Change Magazine (blog).

Our purpose is to help people and organizations develop (more) positive cultures so that both people and performance thrive. Everyone benefits! We have seen too many people who suffer or survive at work, spending time and energy on disengaging, hiding, or obstructing. In such a scenario, everyone loses.

What if you worked in a positive workplace? You and your team would engage (more), innovate, contribute, and give it your best! The world would look different if we all did. Positive organizations are agile, more innovative, competitive, collaborative and productive.

We're happy to connect with you on Linkedin:
