    Our Story

     

    Since 2018, our driving force has been the people we wake up every day to serve. We remain grounded in the lessons learned in North Denver, where our founder, Nate Martinez Jr., was taught by his father, Nate Sr., what it means to be a leader who cares and understands the responsibility of leadership. Nate Sr. entrusted his son with the belief that, with the right core values, anything is possible. After Nate Sr.’s passing, Nate Jr. was inspired to carry on his father’s legacy, always guided by the values and foundation his father instilled. This small business mentality remains at UPM’s core, no matter how much we grow. With these lessons passed down through Nate’s leadership to every employee, UPM’s core values were born, driving everything we do today. United, we overcome challenges and United we celebrate every win together.

    The word “United” was chosen for our company name because it reflects who we are at our core. It symbolizes the strength of collaboration, teamwork, and bringing people together for a common purpose. Fostering unity is symbolized by our logo’s interlocking gears, representing teamwork and collaboration. Every interaction is a true partnership, beginning with defining what partnership means to the client or individual. At UPM Mechanical, unity is more than just a word—it’s how we operate. We unite our diverse talents, work closely with our clients, and deliver exceptional solutions. We believe that unity strengthens us, enabling us to overcome any challenge and achieve lasting greatness. Beyond our company, we believe in the unity of the world. By leading by example, we aim to inspire those we cross paths with in every area of life. Together, we can create positive change, one connection at a time.
    This journey has also been fueled by the inspiration and partnership of Nate’s wife, Danah, who shares his vision and dedication. Together, they lead UPM with their children, Nathan and Audrina, as their driving force. For them, this company is about more than business—it’s about family, legacy, and building a future that their children can be proud of.

    We are invigorated and thrilled to bring our expertise to the ever-growing city of Denver. As proud Denver natives, we care deeply about the growth and well-being of the community we’ve called home for generations. The city’s expansion drives us to push our own boundaries, ensuring we continue to deliver top-tier mechanical and plumbing services that contribute to Denver’s success. For us, it’s more than just work—it’s a passionate commitment to the people and city we’ve grown up with and care about. We are motivated and fired up for what the future holds for UPM.
