Rave Reviews

"Tammy is an amazing presenter. She speaks to her audience and is perceptive about where they are in the process and takes this as her lead. She is also quite good at getting teachers to think about their positions. She leads them toward resolution when they are planting their feet and wanting only to be negative. We at Coronado are so impressed with Tammy and appreciate her helping us get to the next step regarding grading for learning. Our staff benefited from Tammy’s presentation, and we highly recommend her."
