Faculty & Staff
Meet the Team
Hey Spartans,
Stauffer Middle School has a proud tradition of excellence, and I am honored to join a community recognized as both an Apple Distinguished School and a California Schools to Watch campus. These distinctions reflect a school that is not only high-performing, but forward-thinking—where innovation, strong instruction, and meaningful student experiences are part of everyday learning. What makes Stauffer special, however, goes beyond recognition. It is the collective commitment of our staff, students, and families to do what’s best for kids and to continuously improve. That foundation is strong, and it positions us well for what’s next.
At Stauffer, we will continue to Level Up with purpose. For me, that means strengthening systems, continuing to build strong relationships, and ensuring every classroom delivers engaging, high-quality instruction for every student. Our Spartans should feel challenged, supported, and connected every day. Whether through rigorous academics or opportunities in band, drama, robotics, AVID, and beyond, we will continue to expand what’s possible for our students. Together, we will build on what makes Stauffer great while pushing ourselves to grow, improve, and take this school to the next level. I am excited to partner with you as part of the Stauffer family because I truly believe that Stauffer has the best to offer!

Mr. Todd Koenig
Dean of Students
Mr. Koenig started his career in education in 1999. He spent 7 years as an English teacher at La Mirada High School where he coached football and basketball and has been at Stauffer Middle School since 2006. While at Stauffer Mr. Koenig taught English 8 and was the Dean of Students for 10 years. Mr. Koenig has been happily married since 2001 and has a son (Nick) and a daughter (Gia).

Mr. MARK SCHIAVO
Vice Principal
Mr. Schiavo is excited to return to Stauffer Middle School as Vice Principal! He began his Downey Unified career 15 years ago as an English and AVID Teacher at West (now Stauffer) Middle School. For the last 7 years, he has served as Assistant Principal and Dean of Students at Warren High School. He is passionate about creating meaningful, positive learning experiences for all students. In his spare time, he enjoys spending time with his two daughters, playing golf and pickleball, traveling, camping, and DJing. Go Spartans!

Ms. Monique Gavilanes
6th Grade Counselor
Ms. Gavilanes is excited to join Stauffer Middle School as a School Counselor. She has six years of experience as a middle school counselor and is passionate about supporting students’ academic, social-emotional, and personal growth. As a bilingual Spanish-speaking counselor, she values building strong relationships with students and families and creating an inclusive environment where all students feel supported and empowered to succeed. In her free time, she enjoys spending time with her dog, running, hiking, traveling, and exploring new coffee shops. She is excited to be part of the Spartan family and looks forward to a great school year.

Mrs. AndaJo Hayes
7th Grade Counselor
With 22 years of dedicated experience as a school counselor, AndaJo Hayes is passionately committed to fostering the academic, emotional, and social growth of middle school students. Her mission is to empower students to overcome challenges, discover their strengths, and achieve success in their educational journey. AndaJo believes in creating a supportive environment where students feel valued and inspired to learn. Her expertise lies in guiding students through personal and academic development, ensuring they are equipped with the skills and confidence to navigate their adolescent years and reach their full potential.

Mr. Brandon Del Rio
8th Grade Counselor
This is Mr. Del Rio’s 14th year at Stauffer as the 7th Grade Counselor, and he could not imagine being anywhere else. He grew up in Orange County and lives in Placentia with his wife, nephew and his two cats Pebbles and Piper. When he’s not counseling, he enjoys barbecuing, playing the drums and golfing with his friends.
