This is not a one size fits all answer but the minimum you should be working ON the business is 1 day. This should not include admin.
Ideally the most successful clinics we work with have owners/principles that work less that 2 days clinical and their remaining time ON or better still OUT of the business.
If you’d like to figure out where the gaps are in your business or where you should be streamlining processes – get in touch for your business health check.
