TK & Kindergarten

My name is Laura Pavlos and I teach transitional kindergarten (TK) here at Pioneer School.  I have been teaching for 36 years, most of them right here at Pioneer!  Along with TK, I have also taught kindergarten, 1st grade, and 2nd grade.  I absolutely LOVE teaching our school’s littlest learners, watching how quickly they grow and learn throughout the year.  Another really awesome part of my job is that my sister, Mrs. Appledoorn, teaches kindergarten right next door to me!

Although I consider my students to be my children, I also have two grown sons.  My oldest lives here in Sacramento, and my youngest is going to school at UCSF in the dental program.  My husband and I also have some 4-legged children at home…3 cats.  I enjoy reading, baking, going to the movies, and cheering on my favorite team (win or lose), the San Francisco Giants. 

Of course, my very favorite thing to do is to teach!  I can’t imagine doing any other job.  I’m so very lucky to be doing what I love.

My name is Jennifer Appledoorn and I am the teacher of The Puppy Class. I have been teaching kindergarten or first grade for 30+ years. I am married and I have two grown sons. My favorite things to do (besides teaching) are to spend time with my family, which includes my two dogs, Taz and Cooper and to read. Another love of mine is the San Francisco Giants! I am an avid fan and enjoy watching them on T.V. and going to games when I can. I am especially lucky to teach at Pioneer because my best friend who is also my sister, Mrs. Laura Pavlos, teaches Transitional Kindergarten right next door to me! 

My class is located in Rm. 1. If you need to reach me, you can call Pioneer School at 566-1940. You may also reach me by email at . I check my email several times during the day and at least once after school. I am looking forward to a wonderful, fun year with your child!

Hi families!

Welcome to the Safari Pals Class! My name is Amy Rivas and I am your child's Kindergarten teacher this year! This is my seventh year teaching at Pioneer and I’m proud to be a Panther! I’m married and have a seven year old daughter. As a family we enjoy baking, going to the park, watching movies, reading books, and making slime. Over the summer I took up a new hobby of refinishing furniture. I take old, ugly furniture and make it new again. It’s been a lot of fun!

We have an exciting year of learning ahead and I'm looking forward to a fantastic year!
