Whangamata School

The workshop was excellent and promoted great thoughts to consider and reflect on. The giveaways were amazing, and I thoroughly enjoyed the day. Thank you so much. I loved the hand outs, resources, food (coffee), stories, and ‘to the point’ delivery style. Awesome food for thought.

Snells Beach School

Fresh out of the field (so to speak). You know, relate & make your content really relevant & applicable. It was so engaging the time flew; a great model of how to improve and engage boys. Fun, fast paced and full of ideas that I can actually use. An excellent day! Thank you.

Burnside High School

Excellent value for money. Marshall is lively, engaging and he role models how an effective teacher should be.
