Before having our two amazing children, my wife and I ran back-to-back half marathons. Now, we run as a family with our children and dog every morning.

Principal, CPA


I manage cross-border expansion and due diligence projects and lead teams who analyze the quality and sustainability of earnings and the assets and liabilities to be acquired from the seller. Clients count on us to help identify potential risks and opportunities in these engagements.

My expertise includes performing work in the safety and security service industry and alarm monitoring industry, and I work with companies that focus on recurring revenue or Software as a Service (SaaS) revenue models.

I’ve always been incredibly interested in international business, learning about other cultures, and understanding how various businesses operate from an accounting perspective. As such, I have worked on due diligence projects within the United States, Mexico, Central America, Europe, and Asia.

My clients appreciate that I provide timely updates and clear communication through my various client engagements, whereas my colleagues know me for creating a fun, collaborative environment.

With more than 10 years of experience at Plante Moran, I consider my greatest accomplishment being recognized as a subject matter expert within and outside of our firm related to advising companies in the safety and security industry, as well as being named one of the “40 Under 40” professionals by Security System News in 2020. I belong to the AICPA and the Illinois CPA Society. I’m the treasurer and board member of the United States-Mexico Chamber of Commerce — Mid-America Chapter. I graduated with a B.A. and an M.Acc. from Western Michigan University.

My hobbies include traveling and spending time with my wife and two children, Liam and Ady. We’re an active family and enjoy jogging, riding bikes, and playing sports like soccer and basketball together.
