Transfer ownership of Chief organization

Hello,
We have an issue that we need help with.

Our organization has changed it's name/logo and the person who previously created the organization is not longer with us.

Our organization is Chief https://www.drupal.org/chief

I believe the owner is acfind https://www.drupal.org/u/acfind-0 who was a previous employee.

I need to transfer ownership to our team's dept head claymarshall https://www.drupal.org/u/claymarshall.

Let me know if anything else is necessary (or if there's a way I can do this self-service...didn't see a transfer option). Thanks!
