Welcome Panthers!

Welcome to Pioneer Valley High School!  Our goal is to provide our students with a comprehensive counseling program that addresses the personal, social and academic needs of students.  The counselors meet with their students both individually and through group presentations throughout the school year to help them select the appropriate courses that meet their career and post-secondary goals.

We are fortunate to have three guidance technicians that are part of our team.  They work closely to support both our students and counselors. 

  • Sandra Arreguin
  • Vicky Ramos

We encourage you to review important information located in the "files" section above.  Please feel free to contact your counselor by phone at 922-1305 or by email to schedule a conference.

We look forward to working with you!

I am thrilled to be a School Counselor at PVHS. I grew up on the Central Coast and decided to stay close to home for college by attending Cal Poly San Luis Obispo, where I received my Bachelor of Science in Psychology and Master of Arts in Education Counseling and Guidance, with a Pupil Personnel Services Credential. I have previously worked at Cal Poly as an Academic Advisor and in Middle Schools as a student support counselor.

Although I was not born in Santa Maria, I have grown up here and consider it my home! When I left to obtain my Bachelor’s degree in Sociology and Chicano/a Studies at UCSB, my plan was always to come back and serve my community.  After obtaining my Master's degree in Educational Counseling from the University of La Verne I was given the opportunity to live my dream of working as a counselor in Santa Maria. I am returning to Pioneer Valley High School after being gone for 7 years and look forward to working with our wonderful students and families and getting to collaborate with our great staff.

The day that I found out that I was going to be a PVHS counselor, I could not stop smiling; in fact, I don’t think I’ve stopped smiling ever since! I am very happy, proud, and excited to be a part of the PVHS family. I have been a high school counselor since 2003. I have always wanted to work in education; therefore, I prepared by earning a Bachelor of Arts in Sociology and a Pupil Personnel Services Credential from California State University, Northridge, and a Master of Arts in Education from Cal Poly San Luis Obispo. I love working with students!

I am excited to join the counseling team at Pioneer Valley High School. I look forward to serving both parents and students. I attended Allan Hancock College, then transferred to Cal Poly, SLO where I earned a Bachelor Degree in Architecture & Environmental Design. My work experience at Allan Hancock College, Cal-SOAP, College Achievement Now, and the Santa Barbara Scholarship Foundation has given me a greater understanding of how to better serve students. Through my work experience, I decided to pursue a career that would help me to make a greater impact on students. I am currently completing my Master’s Degree in School Counseling with a Pupil Personnel Credential through the University of La Verne. I am looking forward to serving the parents and students of PVHS.

I am Pioneer Valley’s College Coordinator from UCSB’s Early Academic Outreach Program. I am a Guadalupe native and an Ernest Righetti High School alumni. I graduated from the University of California, Santa Barbara (UCSB) where I received my Bachelor’s Degrees in Sociology and Chicana/o Studies. I have had the incredible opportunity to work with hundreds of students from the Santa Maria, Nipomo, and Guadalupe communities. My passion is being able to motivate and inspire students to go to college. Some of my most rewarding experiences are being able to see my students achieve all of their goals and become successful people.  As a college coordinator, my goals are to support, motivate and help all of our students by making them aware of their many options for continuing their education.  I look forward to working with all of you, staff, students and parents.
