We love the mountains and traveling out west. This is a bitter-sweet year for me, as I will be retiring after 23 years of teaching in Cobb County. It has been an honor and a privilege to work alongside the incredibly dedicated and talented teachers in the ISA Program. I have learned so much from my amazingly talented and passionate students.
