Our Teachers

"The art of teaching, is the art of assisting discovery."

My name is Alison Hill. I am the owner & director at Happy Hearts Preschool. I have been caring for children for over sixteen years and taught kindergarten in Petaluma for three.  I originally opened Happy Hearts in my home in 2011.  A back bedroom classroom with a class of 6, quickly turned into a converted garage classroom with a group of 12. In 2016, I realized it was time to spread my wings and open a school outside of my home. And that's when we found the Sonoma-Marin Fairgrounds! It's been an amazing place to provide preschool for children. I am a strong believer in play being the true work of the child.  Allowing children this important time gives them the freedom to explore and discover the world around them. 


I'm raising two beautiful children who are 8 & 11, and one rambunctious yellow lab named Rocket who comes to school with me.  In our free time, we like to take care of our chickens, bunnies and travel down Hwy 1 to take in that fresh ocean air!

Hi! My name is Shay Bacon and I am so happy to be a part of the Happy hearts community and your child’s early education journey! I was born and raised in Santa Rosa and have lived in Petaluma for the past 25 years raising my three daughters with my husband. I love this town and am so excited to contribute to the next generation of this community.


I attended Santa Rosa Junior College where I received my early childhood education degree. Since then I have worked in ECE for a cumulative 18 years.


I believe in a play based approach to learning where children can explore and cultivate a lifelong love for learning and curiosity. Thank you for allowing me to be a part of your child’s experience!
