Mr. Donald Hallam

I started my teaching career here at Clements High School in 2021. As a former engineer, I can tell you firsthand that Algebra is a key that unlocks the world's secrets. Whether it's solving the problems every one of us has in life, such as choosing the best cell phone plans or health care options, or solving the world's problems via careers, Algebra opens doors and makes life easier.

I love my job at Clements, particularly because I believe in the value of what I teach, and I love being able to witness those lightbulb moments.
