Every course will list the provider or instructor hosting it, but not every one of these providers or instructors includes their contact information.
If they do include that information, you will find it in the "About" section on their profile pages.
To find a provider's About section, go to mytablemesa.com, visit the course you have questions about, and click on the name below the course name.
You will be directed to that provider's profile page, where you can see their full Bio, and their "About" section.
If the instructor that you want to get in touch with doesn't have any contact info on their page, you can contact us directly at email@example.com, and we can help you out!
