Adrienne Pratt

Adrienne grew up in Fort Worth, Texas where she attended a public Montessori school from 2nd-5th grade.  She graduated from Ithaca College in Ithaca, New York with a Bachelor’s Degree in Cinema and Photography and moved to the Bay Area in 2003.  As an elementary student, Adrienne fell in love with Montessori principles and experienced first-hand the benefits of a Montessori education. It was this experience that led her to Montessori teacher-training.  She earned her American Montessori Society Primary Certificate from St. Mary’s College in 2008.  During her training, she interned at a Montessori school that was also a farm- complete with goats, chickens, horses, vegetable gardens, and fruit trees. She taught there for seven years, serving as the Lead Teacher and Director for the last four years. Adrienne stopped teaching full-time to have her first child. She is delighted to be a part of the GLM community as a staff member and parent. She enjoys spending time with her husband and sons exploring all that the area has to offer and is passionate about travel, reading, and photography.

Alicia Peterson

grMs. Peterson was born and raised in Sacramento, California. After majoring in Swedish in college in Seattle, she always knew she wanted to return to California and live in the Bay Area. After following some diverse career paths (marketing director at a record label, nanny, professional soap maker, running a pastry kitchen at a coffee company – to name a few!) she finally decided to go back to school for Early Childhood Development. She has worked with young children in different capacities over the years and was ready for a teaching experience. After doing this for a while, she is happy to bring together all of her administrative experience and her love of working in a school setting, here at Grand Lake Montessori. Watching young minds learning new things is a very special experience, and she feels grateful to be in the presence of these students daily. Outside of work, she spends time with her record nerd husband, Joe, and she bakes and makes a lot of messy art projects with her daughters Sody and Mabel.

Danny Tien

Mr. Tien was born in Beiha, China. His family immigrated to this country when he was 10 years old because his parents wanted a better life, especially for him. At six months old, he had an accident and hurt his right leg. He was very lucky to get into Shriners Hospitals for Children and the care he received there changed his life. He attended Merritt College and studied Child Development. In addition he received his Administrative Site Director units and holds a AMI diploma from the Montessori Institute of the Northwest for Infant/toddler level. When he first stepped into a Montessori classroom at GLM he observed how quiet, calm, patient, and well mannered the children were. His teaching philosophy is supporting children to make their own choices and helping them develop intrinsic happiness. He joined GLM in the early 1990s. He taught in a primary classroom for seven years before switching over to work with toddlers. He now enjoys his new role as staffing coordinator. He loves spending time with his family, cooking, and bowling.

Wolfgang Ettenreich

Wolfgang was born and raised in Augsburg, a city in the South of Germany. After enjoying the close proximity of the Alps for years and travelling to many countries of Europe, he visited California for the first time in 1996. In May 2000 he moved to the San Francisco Bay Area. Wolfgang holds a M.S. in Computer Science & Theoretical Medicine from the Technical University of Munich.

After working as a software engineer in the Silicon Valley for several years, he changed his career and received his AMI Montessori diploma from the Montessori Teacher Training Center of Northern California in Mountain View in 2006. After some years as a teacher in the classroom, he switched over to take on more administrative work, bringing together his knowledge of Montessori and an extensive computer background. In 2017 he started teaching robotics classes for elementary.

In his free time he loves playing the Australian didgeridoo and lately a new invention called RAV drum. He is committed to the spiritual path of the Diamond Approach and is one of the very few certified facilitators for Walking-In-Your-Shoes® (www.walking-in-your-shoes.us) in the Bay Area (www.wiys-institute.com).
