William H. Gaggos

Shareholder & Partner

I was born in Highland Park, Michigan, the oldest of four children. My parents were both children of immigrants and products of the Great Depression—my mother a homemaker, and my father a businessman who grew up in poverty, helping support his family by selling newspapers on the streets of Detroit from the age of eight. My father’s background in particular shaped my perspective of family, work, and money.

Through decades of professional practice, I’ve seen how both wealth and its absence affect families. I bring that experience, along with broad technical knowledge of the tax code, business, property, estate and trust law, to every estate and business planning engagement.

I earned my accounting degree from Michigan State University (1992) and my law degree from the University of Detroit (1995). I spent five years as a CPA before transitioning to the practice of law, working with two law firms before founding my own in 2008.

I take pride in the long-standing relationships I’ve built with clients and colleagues and in providing practical, thoughtful solutions that help families and business owners protect assets, reduce taxes, and avoid unnecessary government entanglements.

I live in Beverly Hills, Michigan with my wife, and we have two children (ages 18 and 21). In my free time, I enjoy all things outdoors – hunting, fishing, sailing, hiking, and downhill skiing. I am also an avid reader of historical fiction, psychology, and philosophy.

Shareholder & Partner

I did my undergrad at Michigan State University, where I earned a B.A. in Political Science/Public Administration with high honors in 1978. After that, I went on to law school at the University of Michigan and received my J.D. in 1985.

I started practicing law that same year, working at two mid-sized firms before running my own solo practice for seven years. I then spent several years as in-house counsel for three different companies before returning to private practice in 2007. Along the way, I’ve gained a wide range of experience—both in the law itself and in how to get things done for clients.

My practice has long focused on business, corporate, and real estate matters, with a particular emphasis on commercial real estate transactions. I’ve handled everything from acquisitions and sales to financing, leasing, development, and construction deals—plus secured lending, licensing, and governance issues. After years of working on complex transactions, I bring a strong understanding of both the details and the bigger picture.

My wife and I live in Troy, Michigan, and we’re proud parents of two grown daughters—one a teacher, the other a social worker. I enjoy sports (both watching and playing), traveling, and staying active.
