In a significant move for Spanish-language broadcasting in Colorado, Telemundo Colorado / KDEN, part of NBCUniversal Local’s Telemundo Station Group, has officially named Johan Castellanos as the new anchor for Noticiero Telemundo Colorado. The announcement, made in early January 2026, marks a new chapter not just for Castellanos but for the station’s commitment to local, community-focused journalism.
Castellanos made his anchoring debut on Monday, December 29, 2025, joining co-anchor Kehiry Castillo at the news desk. While this marks his first appearance as anchor, Castellanos is hardly a newcomer to the Telemundo Colorado newsroom. Since August 2020, he has served as a multimedia journalist, covering breaking news and major stories that have shaped the Denver metro area. According to Telemundo Colorado’s official release, he will continue in his role as a multimedia journalist, balancing on-air anchoring duties with the reporting that has become his hallmark.
Tatiana Argüello, President and General Manager for Telemundo Colorado, praised Castellanos’s elevation to anchor. In her words, "Johan has consistently delivered accurate, timely reporting that reflects the issues most important to our local communities. His strong newsroom skills, on-air presence and commitment to local journalism make him a valuable addition to our anchor team." This sentiment was echoed across multiple industry outlets, with TVNewsCheck and NewscastStudio both highlighting his reputation for community-centered coverage and his ability to connect with viewers.
Castellanos’s journey to the anchor desk is a testament to both his dedication and his diverse skill set. Before joining KDEN in Denver, he worked as a multimedia journalist and weather presenter for Acción Noticiero Telemundo, which is part of Action News Now in Chico, California. There, he anchored the station’s El Clima segment, delivering news and weather updates that impacted the local region. This experience, blending hard news with the nuances of meteorological reporting, gave him a unique perspective on the needs of viewers in fast-changing situations.
His educational background is equally robust. Castellanos holds a degree in economics from Universidad Santo Tomás, a foundation that likely sharpened his analytical skills and understanding of broader societal trends. He then went on to complete a master’s degree in journalism at Florida International University, equipping him with the professional tools needed to navigate the increasingly complex world of media. Following his graduate studies, he completed an internship with the Telemundo network in Miami, gaining invaluable experience at the national level before returning to serve local communities.
According to Telemundo Colorado, Noticiero Telemundo Colorado airs Monday through Friday at 5 a.m., 4 p.m., 5 p.m., and 10 p.m. The program is a cornerstone for Spanish-speaking audiences in the Denver area, providing local breaking news, weather, entertainment, and sports coverage. The station’s reach extends beyond traditional broadcasts, with content available online at TelemundoColorado.com and across various mobile and social media platforms. This multi-platform approach reflects Telemundo Colorado’s commitment to meeting viewers wherever they are, a strategy that has earned the station multiple awards for journalism and community service.
For Castellanos, the move to the anchor desk is both a personal milestone and a reflection of the station’s broader mission. His reporting since 2020 has focused on stories that matter most to Denver’s Spanish-speaking community—whether it’s breaking news, major developments, or issues with deep local impact. His ability to deliver clear, fact-based coverage has earned him the trust of viewers and colleagues alike. As noted by NewscastStudio, Castellanos’s reporting often centers on community impact, ensuring that the voices and concerns of local residents are not just heard but understood.
The transition comes at a time when local journalism is facing both challenges and opportunities. Across the country, newsrooms are grappling with questions of trust, representation, and the need to provide accurate information in an era of rapid change. For Spanish-language broadcasters like Telemundo Colorado, the stakes are even higher. Their audiences often rely on them not just for news, but for critical information about public health, education, immigration, and civic participation. The appointment of Castellanos is a signal that the station is investing in journalists who understand these responsibilities and are prepared to meet them head-on.
Before his time in Denver, Castellanos’s work in Chico, California, provided a solid foundation in both news and weather reporting. At Acción Noticiero Telemundo, he was responsible for delivering the El Clima segment, a role that required both scientific understanding and the ability to communicate complex information simply. This experience has translated well to his work in Colorado, where weather can play a dramatic role in daily life and news cycles alike.
His academic journey—from economics at Universidad Santo Tomás to journalism at Florida International University—reflects a commitment to both rigorous analysis and effective storytelling. The combination of these disciplines is increasingly valued in modern newsrooms, where journalists are expected to interpret data, explain trends, and put events into context for their audiences. Castellanos’s background positions him well to navigate these demands, and his internship with Telemundo network in Miami gave him a firsthand look at the inner workings of a major media organization.
For viewers, the changes at Noticiero Telemundo Colorado are more than just a shift in personnel. They represent a renewed focus on community-driven journalism and a promise to deliver news that is both timely and trustworthy. As the station continues to evolve, the presence of journalists like Castellanos at the anchor desk ensures that the needs and interests of Denver’s Spanish-speaking residents remain front and center.
It’s also worth noting the broader context in which this appointment takes place. Spanish-language media in the United States has grown in both influence and reach, serving as a vital link for millions of viewers. Stations like Telemundo Colorado are not just news providers; they are community institutions, helping to bridge gaps in information and understanding. Castellanos’s promotion is a reminder that the future of local journalism depends on talented, dedicated professionals who are deeply connected to the communities they serve.
As Castellanos settles into his new role, viewers can expect the same level of dedication and clarity that has defined his reporting since 2020. With a schedule that brings news to audiences throughout the day—at 5 a.m., 4 p.m., 5 p.m., and 10 p.m.—Noticiero Telemundo Colorado remains a vital source of information for the Denver area. The newsroom’s commitment to accurate, community-centered journalism is stronger than ever, and with Castellanos at the anchor desk, its future looks bright.
In a media landscape that’s constantly changing, the appointment of Johan Castellanos stands as a meaningful investment in both journalistic excellence and community trust.
