RANGELY | In a small town, a person’s dedication can leave a lasting mark on both the institutions they serve and the community they cherish. Diana Sizemore has spent nearly 40 years as a cornerstone of the Rangely School District, offering her time, talent, and heart to students, staff, and the community. Starting as a custodian in 1986, she has worked across multiple roles and remains a steadfast figure, even after retirement.
Reflecting on her early days, she shared how she transitioned from a career in dental hygiene and office management to education. “I was a dental hygienist and office manager at the Rangely clinic, but when circumstances changed, I found myself moving over to the school district,” she recalls. Her work ethic, developed from growing up in a family that managed motels and gas stations, quickly transferred to her new role as a custodian. “You’ve got to care about what you’re doing, and that applies to education too. Maintenance is as important as anything else,” she notes. “We’ve got to keep everything in top working order for these kids.”
Her connection to the students and staff deepened when she moved from custodial work to other roles, including managing the library. Over the years, she also became a fixture at school events, from helping with student council and concessions to serving as the clock operator for volleyball and basketball games for over 16 years. “We are one big team here,” she says. “It takes everybody working together to keep our school running and to support the students in the best way possible.”
After retiring for the first time in 2009, Diana returned in 2012 to work in the library, where she thrived. “I loved the library,” she says. “It was a chance to work with students on credit recovery and proctoring state tests. It was also a great opportunity to help train student leaders through the student council, where we could encourage kids to take control and create fun, meaningful activities.”
Even after her second retirement in 2017, she couldn’t step away. Her commitment to the school and the community has kept her involved as a substitute teacher and paraprofessional. “I’m proud of what we’ve built here in Rangely,” she says. “This is a small but tight-knit community. We’ve raised some incredible kids here, and it’s important to maintain that strong, supportive environment.”
Beyond the school walls, Diana has been a key player in the community as a board member and volunteer for numerous organizations, including the local booster club and the hospital board. “Prom is one of my favorite events,” she shares with a smile. “It’s such an important memory for these kids, one of those moments they’ll carry with them for the rest of their lives.”
Her dedication to the community is equally evident in her role on the foundation board at the college, where she has helped raise tens of thousands of dollars through annual fundraisers. “In this town, we have some of the most incredible people—hardworking, faithful, and dedicated,” she says proudly.
Looking back on her decades of service, Sizemore reflects on the importance of staying positive and continuing to give back. “You’ve got to have strong faith and remember that it’s not always about getting things your way. It’s about working together and staying committed to the people and places you love,” she says. “I hope I’ve made a difference. This community is my tribe, and I’m proud of everything we’ve built together.”
Indeed, her unwavering commitment has left an indelible mark on Rangely and its schools. From maintaining the facilities to mentoring the next generation of student leaders, Diana has ensured that her legacy of service, leadership, and love for the community will continue for years to come.
