Andrew Cockley Principal Andrew_Cockley@hcpss.org
I am excited for another great year at Bonnie Branch Middle School. 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 second year 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 truly excited to be joining the Bonnie Branch Middle School community as your new Administrative Intern. As an educator for 16 years, I have had the pleasure of teaching middle and high school students in North Carolina, Georgia, Texas, and Maryland. I have served as a mathematics teacher, PBIS coach, math content team leader and grade level team leader in Howard County. I have a B.S. degree in Mathematics-Teaching and a M.Ed. degree in education leadership and administration with principal licensure. My family and I relocated to Maryland from Georgia in 2011. My husband is a retired army officer, and we have two amazing teenage sons. We are huge Philadelphia Eagles fans, and you can find us cheering on our team during football season. Being a part of the Howard County Public School System for the past 10 years has been wonderful. I have watched my oldest son, who is a sophomore in college, and my youngest son, who is a rising junior in high school, learn and grow in this school district and I look forward to watching the students at BBMS grow as well. Building positive relationships with parents, students, and staff while watching students grow in a culturally inclusive environment is very important to me. I cannot wait to begin my administrative career at Bonnie Branch in the fall and I look forward to meeting everyone.
