Scott Corso,  Principal

I am humbled and honored to serve as the principal of Black Mountain Middle School. I was born and raised in Northern California. While there, I attended Santa Clara University, majored in history, and received my Masters in Education Administration from National University. I served in education for over 20 years. During that time, I taught 7th and 8th grade humanities, high school social science, English, and video production. I have also been an Athletic and ASB Director.  Before coming to Team Poway, I served the community of Temecula as an assistant principal at Temecula Valley High School.


The best thing I have ever done is marry an amazing southern California girl. My wife Jennifer and I have four children. Jacob and Jessica are grown and on their own, while our two youngest, Dominic and Dante, are students in the Poway Unified School District. In our spare time, we enjoy the beach, sports, hiking, and traveling. I also enjoy officiating high school football. Coincidentally, I am a big sports fan, all Bay Area. Go Giants, 49ers, Warriors and GO RAIDERS.

V-WHITE.jpegIt is a privilege to be invited into the Black Mountain Middle School community as an Assistant Principal! I'm originally from the Los Angeles area and moved to San Diego 4 years ago. I taught high school art and art history for the last ten years in Manhattan Beach and Vista before deciding I wanted to pursue education in a whole new way! I have a BA from Cal State Long Beach in Art Education and my MA from Cal State San Marcos in Education Administration.

I have also taught art classes in Cambodia and English Language classes in China. I've been lucky enough to travel internationally with students to Greece, Spain, France, England, and Costa Rica and to many cities around the country for journalism conferences. 

On the weekends and in our free time, you can catch me and my husband working on house projects and building something new, tinkering with cars, or taking a motorcycle ride! We love our German Shepherd named Ripley (after Ripley from the movie Alien)!

5C046EC7-4243-4E43-9748-723D6889DB11_4_5005_c.jpegIt is an incredible privilege to join the Black Mountain Middle School team as assistant principal.  I grew up in Ventura County and attended the University of Southern California, where I studied print journalism and political science.  After graduating from USC, I earned my teaching credential and master's degree in special education from California Lutheran University.  I have been working in education for fourteen years, starting as an instructional aide and later going on to teach in a variety of grade levels and subjects.  Prior to joining the Poway Unified School District, I had the pleasure of spending several years with Coronado Middle School, where I taught 7th grade math and language arts and served as special education department chair and assistant principal.

I live in the North Park area of San Diego and love cooking, reading, movies, game nights, and USC football.  When school is not in session, you will likely find me traveling the world — I love to explore new places and cultures, and I have never been to a city I didn't want to visit again someday.  I also enjoy spending quality time with friends and family, including my twenty-one nephews and nieces.  I can’t wait to connect with, learn from, and support the outstanding Black Mountain Middle School community.
