Presentation Testimonials

  • “Nature-centric education plays a pivotal role in sparking intrinsic motivation, improving student behavior, promoting effective communication, strengthening cooperation, enhancing academic achievement, nurturing students with special needs and creating healthier, happier future generations. Shawn Maestretti and Leigh Adams’ presentation on Climate Reality will cater to all of the aforementioned advantages of educating students to walk with nature, protect it, and look up to it for answers to everything.”

    Kavitha Satya, Middle School Science Teacher, New Horizon School
  • “Wow. I have heard talks similar to pieces of yours but never one that had ALL of that excellent information in it. The graphics were spot on and made it so easy for anyone to understand what is going on with our planet. I believe that you should take your presentation to people in Congress. Everyone needs to experience this presentation. We do need to garden like our lives depend on it. I am inspired to go and really take my habitat gardening to the next level, starting with using Hugelkultur. Thank you so much!”

    Lisa Bellora, San Diego Landscape Designer
  • “I just attended a beautifully integrated lecture given by Mr. Shawn Maestretti entitled Climate Reality: Regeneration of the Landscape. This wonderful talk illuminated the interconnections between urban gardens, carbon sequestration, soil construction, water conservation, green mulch, and climate change… I highly recommend attending one of his educational programs if you have the opportunity.”

    Rebecca A. Behar-Johnson, recent attendee of Climate Reality: Regeneration of the Landscape presentation
  • “Kudos to Shawn Maestretti for his enthusiastic and skillful presentation of an emerging paradigm for urban gardens. This paradigm frames the global causes and impacts associated with climate change and describes actions that can be applied locally in gardens and landscapes of all sizes to address these causes and impacts.Climate Reality: Regeneration of the Landscape embraces carbon sequestration, heat island cooling, climate adapted plants, rainwater harvesting, habitat enhancement and a vision for gardens of the future.”

    Bob Perry, FASLA, Author of Landscape Plants for California Gardens
