Preschool Teacher

Angela studied Child Development at San Jose State University and has worked with children since 1998. She is passionate about child development and especially enjoys the connections made between teachers and families. Angela says, “The amount of growth that happens for children in the first five years of their lives is so monumental that being a part of it is so amazing.”

Previously, Angela worked at three other play-based preschools. But, it wasn’t until her daughter was enrolled at Playmates, that she discovered how a true play-based program operated. Angela was amazed at the children’s freedom to discover their surroundings, using the tools to solve their problems and create their own worlds. Being a part of Playmates for Angela means helping children build the strong foundations they need to succeed in their futures.

Angela currently holds her Associate Teacher permit and is working towards her Site Supervisor qualifications. In her free time, she enjoys spending time with family, baking, cooking, crafting, and eating the food that San Francisco has to offer.


Young5 Teacher

Courtney joined Playmates Preschool in the Fall of 2021. She moved to San Francisco from Michigan in 2016 after completing her bachelor’s in Early Childhood Education (ECE) with an emphasis on Special Education. She taught preschool-aged children for 11 years and worked as a transitional-kindergarten teacher for five years in the city, where she immersed herself in play-based and social-emotional teaching philosophies. During her first years as a teacher, she fell in love with children who needed more emotional and developmental support. This passion encouraged the completion of a master’s degree from SF State in Early Childhood Education, focusing on Autism. She then spent a year teaching children with Autism before returning to the ECE world. Courtney’s specialty is focused on challenging behaviors, addressing them, and changing teaching approaches based on children’s individual needs and development. She believes in relationship building and how personal connection and understanding of individual needs drive focus and self-regulation in young learners. In addition, she believes conflict resolution skills, self-regulation, and social-emotional intelligence comes before an academic focus.

Courtney brings science and nature to her teaching and loves to help children become inquirers of their world and encourages them to be comfortable playing anywhere Mother Nature provides. Whether it’s in the dirt, mud, sand, water, climbing trees, exploring insects or tree trunks, Courtney believes in teaching children to be kind to Earth and all living things. Courtney enjoys cuddling and playing with her cat, Ziggy (named after Bowie) in her free time. She loves going on hikes and exploring the city and spending time with her friends and family. She also enjoys playing video games, watching films & reading (especially Harry Potter), photography, and resting on her couch. She would love to chat with anyone who wants to know more about her teaching specialty and can’t wait to see what she can bring to the Playmates community!
