Originally from Orlando, Florida, Sandy graduated from the University of Central Florida (“Go Knights!”) with a Bachelor’s of Science in Anthropology in 2008. Soon after graduating she decided to go into education and taught 8th grade Science for 8 years in the Orange County Public Schools. In 2017, Sandy and Ryan, her husband, and their two children Roland (6 years) and Stella (3 years), moved to Key West. This is also when she stumbled upon May Sands Montessori school and fell in love with our school and the philosophy of Montessori education. This exciting new discovery started her on a journey – she became an Upper Elementary Lead Guide for our school and completed her Montessori Elementary I & II credentials from the American Montessori Society in the summer of 2019. Sandy says ” It is a privilege to work with you and your children, and I look forward to a wonderful and memorable year.”

Laura left her home in Lakewood, Ohio, bringing with her more than 15 years’ experience in teaching. Much of her professional experience teaching Family and Consumer Sciences aligns with Montessori pedagogy – teaching life skills such as food and nutrition, career planning, and financial management at the middle and high school levels. Additionally, Laura has experience in Special Education in a variety of settings from elementary through high school. Here at May Sands Montessori School, she offers support primarily to students in our Upper Elementary and Early Secondary classes. Laura enjoys sharing with her students her passion for living a healthy lifestyle and building a love learning. When not at school she tries to be outside as much as possible – running, walking her dogs, and getting out on and in the water. Laura, her husband, their 4 dogs, and a cat are happy to call Key West home and no longer have to makes their commutes in the snow!
