Ms. Dal Bello is an alum of St. Catherine! She received her Bachelor of Science in Psychology in 2015 and completed my Multiple Subject Credential Program at St. Mary’s College in 2018. She was a substitute teacher for several years and taught K-8, but her favorite grade by far is Kindergarten! This is her fourth year teaching at St. Catherine’s, and she is looking forward to a fun year of learning and growing with our youngest students.

My name is Jannette Wilkinson and I have lived in Martinez my whole life and attended St. Catherine's...first through eighth grade many years ago. I have 2 daughters, 3 granddaughters, and a grandson. I taught preschool for 15 years and have been working at St. Catherine's for 20 years. I began as an assistant in K-3 grades and went back to school and received my teaching credential in 2007. I taught 2 years of fifth grade, 4 years of fourth grade, and this is my sixth year of first grade and I am truly enjoying it.

I’m an east coast girl at heart but I moved here to California when I was 16. I graduated St Mary’s College with a BA in religious studies and received my teaching credential there too. I taught second grade at St. Joseph the Worker School in Berkeley for 6 years before coming to St. Catherine of Siena in 2006. I have been teaching second grade here ever since.
