Colleen Grindle Named Principal of Harpool Middle School
Colleen Grindle, associate principal of Guyer High School, has been named the principal of Harpool Middle School. Mrs. Grindle will begin serving in her role as the campus’ leader on January 1, starting the second semester.
“Having spent my entire career in Denton ISD within the Guyer Zone, this opportunity to become a principal, especially alongside my longtime colleagues, has been a personal goal of mine for many years,” said Mrs. Grindle. “Coming from the high school setting, I feel equipped to lead our middle school students to reach their goals and continue to inspire our amazing staff to support our students in the classroom and beyond.”
Mrs. Grindle joined the district in 2006 serving as a seventh-grade English teacher and coach at Crownover Middle School before moving to Guyer High School to teach and coach three sports.
In 2013, Mrs. Grindle joined the Harpool Middle School staff as an assistant principal where she served for three years. In 2016, she returned to Guyer to serve as an assistant principal.
In 2018, Mrs. Grindle helped open the newly constructed ninth-grade center addition to the Guyer High campus to foster a smaller environment within the 6A high school. She was promoted to associate principal in 2020.
“Mrs. Grindle is known for building strong instructional teams,” said Susannah O’Bara, assistant superintendent of academic programs. “Her high expectations paired with her strong belief in our community make her an exceptional fit as Harpool’s next leader.”
Mrs. Grindle earned her bachelor’s degree in speech communication and education from Stephen F. Austin State University and her master’s degree in educational administration from Lamar University. She is currently a doctoral student at The University of North Texas. She and her husband, also a veteran educator, are raising two students in the district.
Harpool Middle School opened in 2008, and Mrs. Grindle will be only the campus’ third principal.
