Meet The TAPS Support Team

One of the best parts of our foundation is we’re all one big team. We work closely together and are in regular contact about the issues that matter. We support each other, and our mutual passion for raising awareness of TAPS has created a strong bond. We’ll revolutionize the way multiple pregnancies are diagnosed, treated and followed up through our fundamental pillars of research, education, advocacy and hope, and advocate for twins worldwide while upholding our mission, vision and values. We are the TAPS Support Team.

We are colleagues, we are advocates, and we are friends. Together, we can achieve anything.

In their spare time, they love cookies, K3, and creating chaos. (and we wouldn't have it any other way!)
