Our Trillium Team

Ryan LaPierre, CMA

Owner

My name is Ryan LaPierre. I am a Certified Management Accountant (CMA). I currently live on a small farm in northwest Ohio with my wife and four children. I enjoy sports, traveling, and spending time with my family. I love any chance to be outdoors, enjoying God’s creation, whether it is farming, hunting, nature hikes, camping, or just star gazing. I chose Trillium, the Ohio State flower, because it not only tells a little bit about me, but it also is a perfect representation of the three services of Trillium Accounting. Bookkeeping, Controller, and the CFO all come together to form a powerful team that can illuminate the numbers into actionable items for your business. Let me help you!
