As chief of staff, she will continue to provide leadership in these areas but will additionally lead the school district’s human resources department.

Courson is a member of Lockhart ISD’s District Leadership Program (DLP) team and a graduate of The Holdsworth Center’s Leadership Program. She and other team members of the LISD DLP facilitated a shift in leadership and culture over the past three years centered on the district values of LockHeart for People, Locked on Excellence, and UnLocking Potential.

She also worked at the Texas Juvenile Justice Department for eleven years as a communication specialist,  legislative liaison, performance and accountability specialist, delinquency prevention research specialist, grant writer, and project manager.

Having devoted 21 years in service to the children of Texas along the continuum, Courson is passionate about ensuring children have the supports and services they need to thrive.​ ​ 

“Lockhart ISD is truly a school district that empowers its staff and students, ensuring we are UnLocking Potential in ourselves and others,” said Courson. “I am grateful to the superintendent and the Board for the opportunity to serve in a larger role, and I look forward to partnering with the LISD HR team to ensure we continue to attract top talent and provide excellent support and service to our amazing staff.” 

“Ms. Courson is an example of our district value of UnLocking Potential,” said Superintendent Estrada. “The Board and leadership team have been intentional in creating opportunities for leaders to continue to grow so they can reach their full potential in Lockhart ISD.”

Director of Strategic Planning and Grant Initiatives - Dana Sidle


Lockhart ISD promoted Dana Sidle from associate principal at Lockhart Junior High School to serve in a district-level leadership capacity as the director of strategic planning and grant initiatives. In this role, Sidle will spearhead the district’s innovative initiatives including the Additional Day School Year through the Texas COVID Learning Acceleration Supports, the Teacher Incentive Allotment to recognize and reward high-performing teachers who meet specific criteria, lead the Texas State Resident Program, and support strategic district priorities around onboarding staff, identifying high potential leaders, and providing role clarity.
Sidle launched her 22-year career in public education in 2000, serving as an English Language Arts teacher at Pearce Middle School in Austin ISD where she thrived in leading teams and content, facilitated school-wide professional development, was co-architect of the 6th-grade Transition Camp and Summer School, and coached volleyball. Her investment in students and staff earned her the honor of Teacher of the Year in 2008. That year, Sidle’s record of excellence launched her into campus leadership as assistant principal at Hornsby-Dunlap Elementary School. The following year, she additionally served as the principal of summer school in Del Valle ISD.

In 2012, she joined the team at Garcia Middle School as the academic project specialist II. She managed and facilitated after-school tutorials and Saturday camps, assisted in the development and evaluation of educational programs, served as a testing administrator, and facilitated academic data meetings. 

Lockhart Junior High School selected Sidle as assistant principal in 2013, providing leadership to the campus by developing and evaluating educational programs; forming partnerships with and communicating critical information to students, staff, and parents; monitoring academic excellence; and tracking progress and performance objectives. Because of her continued commitment to being Locked on Excellence, she was promoted to associate principal in 2019. 

Sidle was selected for The Holdsworth Center Campus Leadership Program for Lockhart Junior High School and will graduate from the program this week. 

“I am a proud product of a Lockhart ISD education, and I’m sincerely honored and humbled to grow from having been a student here to now serving as a leader in a community dear to my heart,” said Sidle. 

“As the district continues to grow and innovate, Ms. Sidle’s leadership will be key in how we leverage resources strategically and creatively to ensure excellent outcomes for both our students and staff,” said Superintendent Estrada. “She is committed to UnLocking Potential in herself and everyone she works with, and I am excited to see her have an impact on a larger scale.”
