These leadership articles are for you – whether you’re a leader, a consultant, a change maker, a professional, a coach or any other human being. What matters is whether you want to make a positive difference.

I am Marcella Bremer, an author, culture change consultant. I am ranked #6 in the Global Guru list for organizational culture. I work with leaders, middle managers, supervisors, HR professionals, OD consultants, and employees to develop a positive culture at work. With Marcel Lamers, I founded OCAI online (culture assessment online) and the online Positive Culture Academy and this Leadership & Change Magazine blog. My books are “Organizational Culture Change” and “Developing a Positive Culture where People and Performance Thrive”. (Available on Amazon).

Marcella Bremer

I graduated from Rotterdam School of Management. My career is as varied as my interests, but it comes down to learning, reading, writing and consulting on leadership, culture and change.

I founded Leadership & Change Magazine with Marcel Lamers – now transformed into this free Blog.

I founded OCAI online with  Cameron & Quinn’s validated Organizational Culture Assessment Instrument, and I consult with organizations around the globe.

I founded the online Positive Culture Academy with a curriculum that helps you apply positive leadership practices at work.

I published several books: “Organizational Culture Change: Unleash your Organization’s Potential in Circles of 10” and the Positive Leadership, Culture & Change Collections.

Last but not least is: Developing a Positive Culture where People and Performance Thrive.

The current state of the world sometimes saddens me – but I’m an optimistic person who likes to make positive change work. Every one of us can create positive ripples that influence our circles of influence. Together, we can amplify our positive difference.

I graduated in Environmental Studies and, after that, in Biology at Utrecht University. During my research for theoretical biology I learned how to code so my career turned in the direction of writing code, designing systems, and websites.

I am interested in a broad field of topics so I also finished courses in NLP and Bodywork before founding a training & coaching company.

Next, I founded OCAI Online with Marcella Bremer. I’m responsible for the back end and a smooth technical flow of this online system that offers the OCAI in several languages to the world.

I also founded Leadership & Change Magazine with Marcella – now transformed into this free Blog. I’m the person who makes things work, and who likes to solve problems.

Last but not least, I’m the co-founder of the online Positive Culture Academy.

Let’s develop more positive organizations!
