“Tracy is a great facilitator. Her input was very helpful to get us talking–very insightful. Thank you for this. It was a great start for the staff to start discussing these issues. It helps us to focus, and not get bogged down in personality ‘quirks’.”

Olive Knight

branch librarian, Boston Public Library

“It was very enlightening being able to discuss difficult issues with co-workers. I’ve learned that we must learn to communicate better as a team so that we can improve our service to the public. Tracy did an excellent job of facilitating and not allowing negative feelings to arise.”
