Assuming that you are a working owner who is actively involved in the day-to-day management of your eyecare practice, I think you need to meet with every staff member at least once a week.
That may sound like a lot. But it’s not. That’s particularly true for newer employees who need your guidance and feedback.
The exception might be if you have ten or more employees. In that case, you can delegate some of the meetings to a full time office manager.
But, for the typical practice with one to nine non-OD staff members, I think meeting once a week is about right.
