Attention Algebra 1 and Geometry Students: Three years of mathematics, including Algebra 1, are required for all California students to obtain a high school diploma. It is critical that students enrolling in Algebra 2 have a strong foundation in Algebra 1 in order to ensure success in Algebra 2. Students who are taking Algebra 1 must pass the California Standards Test (CST) in Algebra 1 with a minimum scale score of 350 (minimally proficient) as a prerequisite into Algebra 2, which is typically taken after Geometry. Students scoring below 350 must retake Algebra 1 prior to enrolling in Algebra 2. If the student does not score minimally proficient (minimum score of 350) on the CST Algebra 1 a second time, the student may still enroll in Algebra 2 after completion of Geometry. Click on the link below for more information and ask your current math teacher if you have any questions regarding your status. CLICK HERE FOR ALGEBRA 2 PREREQUISITE NOTICE.

Throughout my life, I have received several highlights and achievements that I am proud of. At the age of 15, I received the Eagle Scout award. After graduating high school, I was fortunate to have the opportunity to play college basketball at Cal State San Bernardino. From Cal State San Bernardino, I received my B.S. in Finance and immediately entered the professional workplace. Over the course of the next 8 years, I had several jobs that ranged from an Assistant Controller, Financial Analyst, and Database Consultant for several large companies. During this time, I learned a great deal as to how companies operate both financially and professionally. After 8 years, although, I knew something was missing in that while my professional career was self-motivating, I was really not helping anyone other than myself. This was the point in time that I decided that teaching would not only provide me with a nice career but would also allow me to help students. At this point, I got my credential and started working at Madrid Middle School in El Monte. After four wonderful years there, I started my tenure in the Murrieta Unified School District. Over the past 11 years in the Murrieta Unified School District, I have enjoyed working at Creekside High School, Tenaja Canyon Academy, and the Murrieta Adult School. During this time, I have had several achievements including obtaining my Master’s Degree in Business and receiving Teacher of the Year. But even though I have received several honors and achievements in my life, my greatest motivation and highlights have come from the many students that I have worked with in my teaching career. There is truly nothing more meaningful to me than working with students and having the opportunity to get to know them. I am truly grateful that I am a teacher.
