Andrew Cockley Principal Andrew_Cockley@hcpss.org
I am excited to be joining the Bonnie Branch Middle School community this year. My background in school administration covers 19 years in multiple school systems and levels and I enjoy getting to know new people in each of the communities I serve. At Bonnie Branch there is a rich tradition for success that I will look to build upon and I will do everything possible to help make your child's experience a positive one as they prepare for high school and beyond. I started my career in education as a middle school teacher and taught math and computer science throughout high school as well. My degrees come from Gettysburg College (Bachelor of Arts in Management and Finance), Arcadia University (Masters in Math Education), and Johns Hopkins University (Masters in School Administration and Doctorate of Education). I love to learn and hope to instill this in our students too. Being an avid runner and cyclist, I love that Bonnie Branch is located so close to some of the best trail systems around. I look forward to meeting you this year! Andrew Cockley, Ed.D.

I am thrilled to be entering my seventh year in administration and first as Assistant Principal at Bonnie Branch Middle School. In my 27 years in education, I have served in several roles including mathematics teacher, math instructional support teacher, team leader, leadership intern and assistant principal in both Howard and Anne Arundel Counties. I am a strong advocate for student voice and the home-school connection. I am so thankful for the education my own children experienced in Howard County Public Schools and am proud to work with the Bonnie Branch Community to provide a caring, supportive environment for our students. I look forward to meeting all of you!

I am excited to be entering my first year in Administration in at Bonnie Branch. In my previous 14 years in education, I served several roles at the elementary, middle, and high school levels for Prince Georges and Anne Arundel Counties including lead Physical Education Teacher, Alternative One Teacher, Behavior Intervention Specialist, County Wide Restorative Practices Trainer, and Acting Assistant Principal this past school year at the high school level. I believe as educators we are in the business of service; service to students, the Bonnie Branch community, and one another. I look forward to collaborating with the wonderful staff at Bonnie Branch, developing authentic diverse learning experiences, not just for our students, but for ourselves as well, that are grounded in a culture of inclusivity, and excellence. I can not wait to meet everyone, and I am looking forward to a wonderful upcoming school year! -Kion L. Mackell
