 Laird Blackwell

English 9-12

impact teachers headshot laird blackwellLaird received his PhD in Education and Psychology from Stanford University in 1974. After moving to Tahoe a few years later, he taught at Olympic Valley School (now Squaw Valley Academy) for a couple years before becoming a Professor at Sierra Nevada College. After 31 years there teaching various courses in psychology, literature, writing, and mythology, he retired in spring, 2012. He was honored by students as “Professor of the Year” on numerous occasions over the years.

He is an avid hiker and photographer with a special love of wildflowers–he has written (and done the photography for) several wildflower field guides. His latest–Wildflowers of California: A Month-by-Month Guide–was released in May, 2012 by University of California Press.

He lives with his wife Melinda and their menagerie of horses, alpacas, llama, miniature donkey, ducks, chickens, cats, dogs, and parrot in Washoe Valley, where Melinda leads equine therapy and educational programs for at-risk kids.

Laird has an exceptional collection of old books (yes, those hold-in-your-hand artifacts of years gone by!) specializing in 19th century mystery, detection, and fantasy. Although he is looking forward to retirement reading, as his former students suspected, he seems unable to completely retire–he’s excited about sharing some of his passions and experience one morning a week with the students at +Impact School.

Nate Martz

Instructional Guide

Screen Shot 2016-04-04 at 10.29.15 PMA life-long love of learning has turned into a meaningful career as a math and science educator. Growing up in a small Connecticut town, Nate learned to appreciate the value of a good book and a curious mind. He initially studied aerospace engineering at the University of Michigan, working alongside future astronauts in a rigorous program of physics and higher level mathematics. After two years he decided to combine this love of engineering with his musical interests, leading him to change paths and earn a Bachelor’s Degree in Music Production and Engineering from Berklee College of Music. He spent several years working at colleges in the Boston area, teaching and training undergraduate students to produce stage events in technical theatre, dance, and concert music. It was during these experiences that Nate discovered his true passion for working with young people and helping them to implement practical applications of mathematics and scientific inquiry.

Nate further developed this work by becoming a high school teacher in New York City, where he taught math and science at an Expeditionary Learning school in the South Bronx. During this time he earned his Master’s Degree in Education from St. John’s University. He also coached the cross country and track and field teams, sharing his love for the science and art of distance running.

When he’s not the classroom, Nate spends his time training for marathons and triathlons. He has also been known to find mathematical patterns in his musings on the drums and guitar. He’s looking forward to working alongside +Impact students and staff to bring his passion and experiences to Tahoe.
