Dr. Renee Garriss - PrincipalDr. Katie Derman - Principal


Welcome to our outstanding learning community at Mountain View Elementary School! I am honored to serve as the principal of this exceptional school, and I am thrilled to embark on this educational journey alongside our dedicated staff, engaged students, and supportive families. As an enthusiastic educator, my passion lies in fostering a love for learning, cultivating positive relationships, and empowering students to reach their full potential.

The Cobb County School District has been my home as a student, a teacher, and now as a leader.   I have both elementary and middle school experience and most recently served as the Assistant Principal at Pickett’s Mill Elementary School. The upcoming school year will be my seventeenth year in education and fourteenth year in Cobb.  I am so excited for this next chapter in my educational journey, serving as your principal at Mountain View.

Collaboration is at the heart of our educational philosophy. I firmly believe that strong partnerships between teachers, parents, and the community are essential for student achievement. I am dedicated to fostering open lines of communication and creating a supportive network that encourages active involvement from all stakeholders. Together, we can empower our students to become critical thinkers, effective communicators, and compassionate citizens.

As Principal, my door is always open, and I encourage open dialogue. I am excited to work closely with our exceptional faculty and staff to foster a culture of innovation, continuous improvement, and lifelong learning. I believe in recognizing and celebrating the unique talents and strengths of each individual in our school community, inspiring them to embrace challenges and persevere through obstacles.

I am truly honored to be a part of the Mountain View family, and I look forward to building strong connections with each and every one of you. Together, we will create a nurturing and empowering environment that will inspire our students to dream, achieve, and make a positive impact on the world.

Warm regards,

Dr. Katie Derman
