David holds a Master’s degree in taxation and a Bachelor of Science degree in Business with a concentration in Accounting, both earned from San Jose State University. He is also a certified public accountant in the state of California.
Within two years, Brian’s exceptional work ethic earned him a promotion to the position of Estimator/Foreman. In this role, he bid on projects and led a crew in completing various construction tasks, ranging from landscaping to roofing and everything in between. This experience provided Brian with a comprehensive background and extensive knowledge in different areas of construction. In the late 1990s, Brian established his own residential and commercial construction company before transitioning to manage a design and construction firm specializing in residential and commercial projects in the Oakland Hills.
In 2014, Brian joined Magnum as a Drywall Project Manager and has since risen through the ranks to his current position as the Division Head for Drywall, Plaster, and Wood Framing. Apart from his work at Magnum, Brian loves spending time with his wife, children, and grandchildren. He also enjoys pursuing outdoor activities such as hunting and fishing, as well as watching baseball, football, and various motorsports.
Within five years of joining Magnum, Jeff was invited to become one of the company’s shareholders. Soon after, he became Magnum’s first Vice President. Over the following two decades, Jeff played a crucial role in overseeing numerous large-scale projects in the field, contributing significantly to Magnum’s reputation and success as a company known for handling challenging projects with tight schedules. Jeff demonstrated excellent customer relations skills while also mentoring many of Magnum’s top field workers.
As Magnum expanded, Jeff’s expertise was increasingly required for mentoring and management responsibilities. From 2013 to 2018, he supervised Magnum’s Southern California office, regularly traveling between Southern and Northern California. Today, Jeff continues to train, oversee, and manage field personnel while also taking on special leadership projects. Outside of work, Jeff enjoys spending time with his wife Teresa, their children, and grandchildren.
In 2009, Reka joined Magnum as an intern in the accounting department. However, when an opportunity arose due to a vacancy in accounts payable, she eagerly stepped into that role. Later, when the economy faced further recession and Magnum’s CFO position became vacant, Reka stepped up to fill the position and provide assistance. Despite her limited experience, she compensated with a strong work ethic and exceptional ability to quickly grasp new concepts, helping Magnum navigate through that challenging period. Today, she serves as Magnum’s Controller reporting to David Kirst, the company’s CFO. Reka proves to be an invaluable asset in various areas within Magnum.
Outside of her professional endeavors, Reka loves spending quality time with her husband and two children.
In 1979, Jann embarked on his career as a painting & wallcovering estimator at a commercial firm in San Jose. Over the next three decades, he held positions as Chief or Head Estimator at several prominent finishing contractors in the Bay Area. Since 2010, he has served as the head of the Painting & Wallcovering Division at Magnum, commuting weekly from his residence in Phoenix, Arizona.

Driven by his passion for flying, Gary decided to pursue a pilot’s license. He utilized this license to attend classes at Pepperdine University in Southern California, where he obtained his Master’s Degree. As Magnum experienced growth and expanded its divisions to include ceiling, painting, specialties, and plaster, Gary continued to develop diverse interests. He acquired the San Martin Airport and established Magnum Aviation, while also taking ownership of the Saddle Rack, the largest western bar in the western United States. Gary successfully managed both Magnum Aviation and The Saddle Rack alongside his leadership role in Magnum Drywall for many years. However, he recently divested himself of the airport and the western bar. Currently, Gary continues to lead Magnum while prioritizing his family, including his wife TJ, his daughter, and four grandchildren. Throughout his career, Gary has earned tremendous respect from the industry, employees, and customers. This is evident from the fact that many of Magnum’s employees and customers have remained loyal for over 30 years.
In the midst of the dot-com slowdown in 2001, Eddie found himself compelled to learn the skill of estimating drywall on commercial projects out of necessity. Then, in 2006, at the request of some of Magnum’s clients, he established Magnum’s Painting and Wallcovering Division. Once again, driven by necessity, Eddie taught himself how to estimate painting. His responsibilities grew as Magnum continued to expand its services, incorporating ceilings, painting & wallcoverings, specialties, and plaster. He successfully managed a workforce of over 700 union field personnel and currently works in collaboration with division heads to oversee a thriving company that has remained true to its original roots and core values.
Outside of his professional life, Eddie finds joy in raising cattle, farming, hunting, and spending quality time with his wife Suzie and their two sons.

Since joining Magnum in 2014, Sean has taken on a leadership role as the Division Head of the Specialties Division. Through his efforts, Magnum has established itself as a major Division 10 subcontractor and expanded its collaborative finishing capabilities.
