Is it possible to center the post

Hi @Michaela Münch

Do you mean, you want to center align About Fenz section of home page?

If yes, please login to wp-admin and go to Appearance >> Customize >> Additional CSS

Add following lines of CSS to make it center align.

.home .pt-team-items-wrap {
    float: none;
    display: block;
    text-align: center;
}

If you are looking something different please let us know.

Thank you.
