Theresa Hentzel, Teacher Mixed Age Class

Theresa was born and raised in Palo Alto. She studied sociology at California State University, Sacramento, and has received her Master Teacher Permit from the State of California Commission on Teacher Credentialing. Theresa is a dyed-in-the-wool Giants fan and a bit of a gadfly. She married “the boy next door” (a PNS alum) and they’ve been together twenty years. They have a son, Jack, who went to PNS as well. Theresa joined PNS as a parent in 2009, but when Jack was promoted to elementary school she didn’t want to leave! She joined the PNS teaching staff as an Assistant Teacher for the mixed age class at the start of the 2011/12 school year because she loves everything about it: the philosophy of the school and the parents who believe in it, the sense of community, the fantastic play space, and the snickerdoodles. This year she is looking forward to returning as lead teacher in the Mixed Age classroom. When she’s not at PNS she can be found biking around town or goofing off with Jack. She enjoys reading, cooking, swimming, photography, and being outside. Theresa believes in parent involvement, play based learning, and paying things forward.

Kathy Sherman, Music

Kathy writes: “I’m so honored to be able to teach your children music. I hope to create a musical community where our students and their families will share and enjoy music together for many years to come.” Kathy is originally from Los Angeles and began her professional music career at 15, playing guitar and bouzouki. It was there that she observed the emotional impact music has on people. Ever since then it has been her goal as a musician to create this joy in my audiences. Kathy studied ethnomusicology at UCLA and earned a degree in classical guitar performance from the SF Conservatory of Music. She received my early childhood music education in a joint class from Music for Minors and Foothill College. She worked for 5 years as a music docent for Music for Minors at Ohlone School in Palo Alto teaching the K-1 classes. She was also a member of People of Note, an organization bringing concerts for children to the Bay Area. Kathy is married to Len, an analog engineer who dabbles in machining and metal art. She has two almost-grown sons; her older son Nathan is at Berklee College of Music in Boston majoring in sound design and production and her younger son Max is at Willamette University. Kathy plays with her Greek group, The Plaka Band. Her CDs include: “Listen to Your Mama” and “Singing on a Star” with her band Hey Mom!; “Welcome to the Folk Song Cafe” with her band The Good Folk Collective; and “A Time to Sing, A Time to Dance” and “New Songs of Old Athens” – this one, a Grammy semi-finalist for best world music album – with The Plaka Band.

Virginia Debs (Grandma Virginia)

Grandma VirginiaVirginia is a native Californian and was raised in small towns throughout the West and Midwest, spending summers in Berkeley with her Swedish grandparents. She studied at UC Berkeley, Harvard, and Tufts, and holds a Life Credential in Parent Education. Virginia began teaching parent education at PNS in 1969. In 1996, she began team teaching, which allowed her more time to travel. Now 92 years of age, Grandma Virginia has only the occasional opportunity to visit classes, but her visits are memorable! She loves teaching about nature and science, starting with all the things to be found on our great PNS yard. She and her late husband, Bob, have two children – Douglas, an engineer (and railroad enthusiast), and Missy, a communications specialist working overseas. Virginia is enthusiastic about people, the out-of-doors, books, opera, ballet, cooking, and (of course) PNS. The Grandma Virginia Memory Project, a series of interviews with Virginia, was completed as a gift for her 82nd birthday in 2006.
