Hello @bpeyecare! Yes you can do this! 

The first step is to create a Staff Profile for your employee from the Appointments section of your Dashboard. Some profiles are preset: Service Provider, Front Desk (it sounds like this is what you need - they only have access to the Appointments Calendar), and Manager. 

You can then further restrict/grant more access to an empoyee from the employee permission group. To manage the permissions for a staff profile go to the Employees section of your Dashboard > click Permissions. You can toggle off everything except 'Access Appointments'.

If you have any other questions about this let me know !
