Certificate Highlights

This certification is mostly about managing people, although there are tips and tools for you to use to manage your own time and projects, also critical skills for any manager.

When you understand the differences in how to approach people with different work and learning styles, you will be able to leverage the best of them and significantly improve your organization's success, regardless of size.

In this in-depth certificate program, Dr. ArLyne Diamond shares her 30 plus years' of experience helping people get the best out of themselves and others. The program covers a lot of territory - all of it critical in today's business environment - and it does so with concrete examples and real-world insight that will help make it all more useful and relatable.

Whether you are an experienced manager or recently promoted, the courses here will add immeasurably to your management skills. Instead of feeling frustrated because of being misunderstood – or having people not understand your needs and your needs from them – you will find that you are now able to communicate with people in a manner that works best for them and results in the best outcomes for you and the entire organization.
