Originally from Missoula, Montana, Jack Larsen brings a strong foundation in mechanical systems and a passion for hands-on problem-solving to A3 Engineering. He earned his degree in Mechanical Engineering from California Polytechnic State University, San Luis Obispo, where he developed a deep interest in HVAC&R systems through both academic studies and real-world applications.

Prior to joining A3, Jack completed two internships with commercial refrigeration engineering firms. During this time, he gained experience in thermal system design, interdisciplinary coordination, and MEP drafting using Revit. His work focused on applying industry-standard tools to develop effective solutions that meet both technical specifications and client needs.

Outside of engineering, Jack enjoys skiing, hiking, and boating. He is also a violinist and a former Spanish immersion student, continuing to practice the language whenever possible. Now based in Los Angeles, Jack is eager to grow professionally while exploring everything the city has to offer.

Jack is excited to be part of the A3 team and looks forward to contributing to impactful and well-designed projects.
