I just attended the best one hour learning session in my career while at the ASAE Great Ideas Conference. I received more useful tips about management and leadership during this session than I have in 30 years of professional business management and continuing education courses. If you want to teach your managers how to be more effective (or need to brush up on your own skills), I recommend hiring Shari Harley to help you build business relationships that really work!
Every manager (from CEO of a Fortune 500 Company to a shift manager at McDonalds) should be required to take ten hours of training with Shari before being allowed to manage people.
