How it began
The TxMiller Foundation was established in 2024 by GenDx co-founders Erik Rozemuller PhD, and Wietse Mulder PhD. The Foundation is partially funded through the sale of GenDx in October 2022, along with donations from individual donors and private organizations.
Since we understand the impact a donor can have on a patient’s life, we are committed to advancing the field of Life Sciences, with a special focus on transplantation. Our mission is to improve the quality of life and survival of transplant patients.
The name TxMiller reflects both our mission and our heritage:
‘Tx’ refers to the field of transplantation.
‘Miller’ combines both founders’ last names and honors their Dutch heritage, the country known for its renowned windmills.
