Bertrice Dawson - English

I received a B.S. Degree in Chemistry from Spelman College in Atlanta, Georgia and continued post graduate studies in Biomedical Sciences at the University of Santiago, Dominican Republic. After deciding to teach, I worked in underserved public schools in Arkansas, Texas and Los Angeles, filling positions with the greatest need as requested by school administrators.

Although I was reluctant at times to teach subjects outside of my major, I eventually gained proficiency in most common core subjects for middle school and high school students.

Opportunity knocked with a request for a teacher specializing in multiple subjects and grade levels, and I responded. I was whisked away on a world tour (including 50 major U.S. cities) as the teacher for young, multi-platinum, Grammy Award winning artists. As I toured, taught and managed all aspects of the educational requirements by day and watched my students perform at huge venues by night, I saw the immeasurable benefits of being flexible in my approach to sharing knowledge. I also realized that for me, teaching is much more than the didactic pronouncement of facts. It is an art, which when well-crafted, motivates students to press for excellence in their lives and academic goals.

I continue to share my 20+ years of academic knowledge in Northern California where I also enjoy family time, practicing my favorite songs on the piano, and converting my rejected movie scripts to mystery novels for young adults.

Gary Lauderdale - Mathematics, Statistics, Data Science

Hi!  I’m Gary Lauderdale and since 2006, I’ve been committed to sharing my passion for mathematics and fostering a love of learning in my students.  I teach high school and college courses and I’m excited for each opportunity to empower students and equip them with the knowledge, skills, and strategies necessary to succeed in and out of class. 

I have a master’s degree in mathematics from the University of Houston and undergraduate degrees from Florida State University.  I was featured in the book Teach Like a Champion 2.0, and I know the difference between teaching and telling.

I believe that responsible analysis is the pursuit of truth, and that mathematics is its vocabulary.  In order to share this idea and promote curiosity and enthusiasm for the subject, I authored the Statistics 2 course, Elements of Data Science, which has been adopted and published as the statewide curriculum in Texas. 

I spend my free time reading, playing guitar (admittedly, an activity for which my enthusiasm greatly outweighs my talent), woodworking, hiking and watching Kung Fu movies.

Pelumi Kolawole - Chemistry

He’s able to bring his communication skills as a healthcare professional in breaking down seemingly complex chemistry concepts into easily understood concepts for students. He’s also pursuing a diploma in cybersecurity at the Alberta Educational Center. 

What he loves most about teaching at CGA is the calibre of students who continually demonstrate a high level of grit and responsibility towards their academic and life pursuits.

Outside of teaching and learning, Oluwapelumi is an avid football fan and ardent supporter of Manchester United Football Club. He equally enjoys spending his time volunteering with his local community organisations in tackling drug and substance abuse in teenagers and young adults.
