Martina Simunek-Suarez, Teacher at Shepherd Valley Waldorf SchoolMartina Simunek-Suarez, Fourth and Fifth Grade Teacher

According to Martina, her life has been a little bit as Bohemian as her name sounds. She was born in a small town in Lower Austria. Her mother's family were World War II refugees from Serbia, and since they had been uprooted, they leaned even more on their German traditions, Catholic faith and conservative beliefs. Her father was from Bohemia where there was much more liberalism and much less religion. On top of that, her father had grown up in a steel town in one of the socialist strongholds of Austria. So Martina moved back and forth between these two worlds. One might think that she ended up all confused, but she really liked it.

When Martina entered the University of Graz, she continued with a good mix of interests: starting with English and Russian, then adding Geography and eventually ending up in the Vietnam War Literature Collection at CSU in Fort Collins. There she met Julian, and while continuing to travel and work in Europe and various parts of the U.S., they started a family. They and their two boys, Markus and Matthaeus, all love the mountains. They hike, camp, fish and ski. Martina loves to read and also enjoys painting, tiling, carpentry work, electrical work, plumbing, gardening, and a bunch of other fun hands-on things, preferably with power tools. Martina was first introduced to the Waldorf philosophy years ago by her cousin, who, just like Rudolf Steiner and Martina herself, grew up in a little town in Lower Austria. After a whirlwind year back in good old Europe, teaching at the Freie Waldorfschule Wien West, Martina is back with some new ideas!

She stayed at this highly idealistic, Anthroposophical based school and biodynamic farm, closely living and working with ‘Children in Need of Special Care.

Here Cristina also discovered her love of Eurythmy. She had always felt very close to nature and it was fascinating to her that this art form allowed her to express the gestures of nature and cosmos through movement. She went on to study the artistic, pedagogical and therapeutic aspects of Eurythmy in Stuttgart, Bavaria and Switzerland.

Cristina taught for eight years of in a Waldorf School in Hamburg for children with a wide range of developmental challenges. She was part of a performing Eurythmy group and she initiated and directed a number of fairy tale productions, which were performed publicly. In the summer of 2000, Cristina was ready for new challenges.

Cristina came to Boulder to teach Eurythmy at Shepherd Valley. She immediately felt drawn to her new colleagues and the school community. With all the hiking and dancing opportunities that the area has to offer, Boulder seemed an ideal place to settle down.

Brightin Schlumpf, Teacher at Shepherd Valley Waldorf SchoolBrightin Schlumpf, Violin

Brightin was born in Seattle, WA to loving and creative parents who chose her name due to the stunning brightness of the morning in June when she was born. Brightin spent her first 10 years on Vashon Island, in Puget Sound, during which time she was exposed to diverse styles of education, peaking her interest to later be involved with Shepherd Valley Waldorf School. On Vashon, Brightin started Suzuki Violin studies at the age of 6. She asked her mother if she could start violin after observing her peers play and longing to be able to join them in their music making.

Following high school, Brightin attended Cornell University, initially planning to pursue medicine, but soon realizing her calling was in music. Thus, she graduated cum laude as a music major. Brightin also ran Division I cross-country/track at Cornell her freshman year, but soon realized she needed to focus more on her academics and violin in order to be successful. She continues to run and has since completed four marathons. Brightin moved to Boston following her graduation from Cornell, where she completed her first MM in violin/viola performance at the Longy School of Music. At CU Boulder she completed a second MM in viola performance as the graduate teaching assistant to Erika Eckert, and was lucky enough to work with Erika and Geri Walther of the Takacs Quartet.

Brightin is delighted by her position at Shepherd Valley as she gets to work with wonderful children and to enlighten them on the power of music as a tool for communication, an opportunity to develop discipline, and a way to bring beauty to someone else’s life through playing.
