Jeff Boxx, MBA, CPA

Jeff Box is a Partner in LSL’s Tax & Advisory department, and he views the CPA profession as far more than crunching numbers. For Jeff, each engagement is a chance to be a trusted advisor—someone who can untangle complexity, calm anxieties, and chart a clear path forward. “Every day brings new challenges,” he says, “and the thrill of making a difference for my clients keeps the work interesting and fulfilling.”

Jeff’s practice spans manufacturing, real estate, construction, and professional services. Whether he’s helping a startup get off the ground, guiding an established business into a new market, orchestrating a seamless succession to the next generation, or structuring a company sale, Jeff thrives on crafting solutions that shape long-term success. Clients appreciate his ability to translate dense tax regulations into actionable strategies that reduce risk and unlock growth.

His passion for accounting ignited in college, where a natural talent for numbers met an emerging fascination with business strategy. Today, that same spark drives him to mentor the next generation of professionals. Jeff empowers his team to adopt a growth mindset—encouraging curiosity, continuous learning, and the pursuit of each person’s unique niche within the firm.

What motivates Jeff day after day is simple: seeing clients achieve their goals. No puzzle is too complex, and no situation too unique. With a calm demeanor and an eye for opportunity, he turns challenges into stepping-stones—and makes sure his clients, and his team, move forward with confidence.

Off the clock… When he’s not at work, Jeff can be found cheering on his kids at their sporting events or enjoying a UCLA football game. In his free time, he enjoys camping and going to the beach with his family. You can also find him savoring a delicious Italian dish!
