CRIT Auto Welcomes a Familiar Leader
After 47 years of dedicated service, Winstill Humeumptewa Sr. has stepped into the role of Fleet Manager of CRIT Auto, bringing with him decades of experience, leadership, and deep pride in the work he does for the Colorado River Indian Tribes.
Winstill began working at CRIT Auto in 1979. Born and raised in the community, he returned home after completing his automotive education to put his skills to work serving his people. Over the years, he has worked his way through nearly every role in the department, gaining hands-on experience as a mechanic, supervisor, service manager, and most recently as Acting Auto Shop Fleet Manager.
His decision to apply for the manager position came after the retirement of former manager Fernando “Bo” Flores. Winstill credits Bo’s leadership, mentorship, and strong work ethic as a major influence and source of inspiration throughout his career. Having worked side by side with him for many years, Winstill felt prepared to take on the responsibility and continue moving the department forward. 
Winstill oversees a fleet of more than 300 tribal vehicles serving multiple departments. His goals include rebuilding and strengthening his crew, improving shop organization, and modernizing operations. One of his immediate priorities is cleaning up the shop area and removing unused gas pumps and tanks that are no longer in service.
Supporting his staff is central to Winstill’s vision. He plans to keep his team up to date through trainings, educational videos, and courses, emphasizing that knowledge and skill development are key to quality service. He describes his leadership style as firm, noting that quality work is non-negotiable. Every vehicle, he says, should be safe, reliable, and properly tested before returning to service.
While CRIT Auto primarily services tribal vehicles, Winstill hopes to eventually reopen the shop to the community once staffing is full. He wants the community to know that even when repairs take time, the work is being done with care and commitment.
Winstill says he is proud of his crew, whom he considers family, and proud of the work they accomplish together every day. After nearly five decades at CRIT Auto, his dedication remains strong, driven by a desire to provide dependable service to the Tribes and give back to the community he calls home.
Congratulations to Winstill Humeumptewa Sr. on this new chapter as the Fleet Manager for CRIT Auto.
