The ZLS Story

Dan and David Zimmerman are brothers who, after high school, took two unique paths in their education and careers. Twenty years later, in the summer of 2023, David joined Dan and a few of his friends on a trip to Orlando, Florida. During that trip, one of Dan’s friends mentioned he didn’t understand the value of his current bookkeeper.

Dan and David quickly realized they had the combined skills and experience to offer their friend a better bookkeeping solution. This conversation sparked an idea, and by the fall of 2023, the Zimmerman brothers met in Southern California to develop a strategic business plan. Their goal: to combine their professional strengths and shared values to create the foundation for ZLS Bookkeeping.

The initials “ZLS” are embedded in both Dan and David’s names—but more importantly, they represent their ZeaLouS passion for partnering with small business owners in the health and wellness industry. ZLS Bookkeeping is built on the mission of helping our clients stay focused on improving their clients’ lives, while Dan and David handle the core business management processes. Their services provide decision-quality financial insights designed to help businesses scale and grow with confidence.
