About Us

The Edgeline Difference.

Edgeline has more than 30 years of hands on, practical experience in shaping workplace environments into an effective culture that minimizes conflict and maximizes results. 

Learning should be both interactive and fun! Edgeline uses both of these principles in structuring all of its workshops to make learning and change both easy-to-learn and easy-to-use.  With 100% group participation, you'll see meaningful results quickly.

The Edgeline program works primarily from the experiential learning perspective in teaching a variety of skills.  An Edgeline workshop focuses on giving the participants the minimum amount of information necessary to get a concept across.  The participants are then given opportunities to practice the skills in a learning laboratory setting, where the completion of tasks is not paramount to the learning process.


Give Your Company an Edge.

Believing that any group is only as effective as the relationships of its members, Edgeline interventions emphasize the interaction between group members while they are completing a task.  The tasks will not attempt to replicate the normal activities of the group members.

However, the way they communicate their given pieces of information, how well they listen and utilize the resources available to their group will indicate certain tendencies towards how they solve problems and communicate in their regular environment, and will give insights into the effectiveness of the relationships between members. 

These reflection points become opportunities to introduce new transferable skills.

A Chinese Proverb States:

What I hear, I forget. What I see, I remember. What I do, I KNOW.

We like to add:

What I KNOW, I DO.

This philosophy governs every Edgeline workshop.  As new skills are discovered or introduced, the group is given opportunity to practice the new skills, which increases transferability.
