Core team

The activities of the foundation are coordinated and carried out by the Core team, which consists of 12 people, including the board. The Core team acts as an extended Board. They define the strategy and operational plans, set and manage standards for fundraising and research (contracts and contract management), drive communications and PR within and beyond the OI community, manage the financials and compliance, manage projects, develop relationships with funding institutions, support volunteers and manage the annual research proposal rounds.

The Core team consists of highly skilled and motivated professionals from the following sectors: IT, Finance, Fundraising, Communications & PR and Learning/Capability Building. They all have significant experience working internationally and across different cultures. The Core team comprises nationals of Germany, Latvia, Poland, The Netherlands, UK. They meet face-to-face on a monthly basis to discuss all matters concerning the foundation.

Since 2017 she is the CEO of the Foundation. She has 3 children. She did not know of the existence of OI until she got had her third child in 2006, Sophie. This was the reason for her to delve with her heart and soul into the possibilities to improve the quality of life of people with OI. “Sometimes you have to deal with a change in your life, that touches your life deeply. For us, that was the arrival of a child with OI. It took a while, to understand what it means to have a child with OI. By now we have found our way. We have a strong network in the medical world and the (international) OI world and we know: there is so much to improve. Progress in the medical world is huge. Through fundraising we can make these techniques accessible for the rare disease of OI. “I am keen to do anything I personally can to improve the quality of life of people with OI. Anything!”

In addition to these four permanent board members, there are a number of people who belong to the so-called “core team“. That core team meets 10 times a year to discuss progress and to go through the action points.

Peter Mekking
Core-team member

In 2012, Dagmar and I founded the Care4BrittleBones Foundation. In 2006 our daughter Sophie was born who turned out to have Osteogenesis Imperfecta. Quickly we found that there were so many unknowns about this condition. Each country has its own protocol regarding operations (with regard to ‘rods’ for example) and with regard to medication in the form of bisphosphonates. Little research was done because of the too small size of the population and lack of financial resources. When Sophie broke her neck we decided to take action. Something had to be done about it. The plan to establish Care4BrittleBones was born with that in mind: “Stop standing at the side lane, but try to improve the situation”


Lieke Mekking
Core-team member

My name is Lieke Mekking. I have two healthy adult children that I am very happy with. I am Peter’s sister and I have seen closely how many concerns you can have as a parent if your child is not healthy. I am also greatly impressed by what Peter and Dagmar have achieved with the Care4BrittleBones foundation and the vision and ambition to not only raise more money for scientific research but also to bring the experts together at an international level. “I would like to contribute to that”
