How do you motivate pharmacy for them to become excellent professionals ?

Well as a Manager you can utilize these skills.

Regular Update course/seminars(Can be organized by you but with supervision). I feel and know that knowledge can make someone act wisely. So, you might include proffessional way of working as a theme or a subtopic of a theme during the seminar.

You can also utilize rewards, awards etc like Best neatly dressed pharmacist, or Best organised pharmacist. This may also work. You can do this based on client's survey or other workers'.
