Mrs. Colleen Kosterman

I am very fortunate to be able to teach for going on twenty-one years in Rockwall ISD and going on ten years at Howard Dobbs Elementary. Prior to teaching at Dobbs I taught sixth grade math at Amy Parks Heath Elementary for six years, and before that I taught third grade self-contained for four years and Life Skills for one year at Nebbie Williams Elementary. 

I have been married to Chris Kosterman for 36 fun-filled years. Chris and I have been living in Rockwall for the past twenty-two years. We have two sons, James Alan and Kenneth Roderick (Rod), who make us very proud parents. Before moving to Rockwall we lived in Paris, Texas, where our sons were born and were fifth generation Paris natives.  

I enjoy being with my family, taking care of our home, being outdoors, working out, keeping up with the Texas Rangers, and doing whatever I can for my students.

I'm looking forward to getting to know and working with my new fifth grade students and their families this year. Please feel free to contact me if you have any questions or concerns this year.
