Diversity and Inclusion

As a company founded and led by doctors, we too pledge to do no harm and to serve those who provide care. Following the tragic deaths of George Floyd and so many others, we join those who advocate for social justice and equality. For decades, we have supported the health of our communities by standing with doctors and promoting access to care. This commitment to health also includes opposition to racism in any form.

We serve our members through a diverse, talented workforce. We treat our members and our colleagues with dignity and respect. We prohibit discrimination in any form.

TDC Group will work tirelessly to ensure our leadership and employees reflect those we serve around the nation, and we will continue to maintain an inclusive, respectful culture.
