About / the long story, kept concise

Engineer, entrepreneur,
and author.

My children and grandchildren are the most important part of my life. I grew up in Clio, Michigan, and have made Midland my home for more than twenty years.

My career began in automotive test engineering and industrial automation, continued through custom systems integration and twelve years in Dow research and development, and now includes Molly’s Grape & Citrus Company and Mangrove Publishing.

Engineering

At Dow, I worked with laboratory systems, bench-scale experiments, and pilot plants across multiple R&D businesses. I became the R&D technical leader for process automation. I am also named on two U.S. patents, both of which grew out of practical engineering needs.

Entrepreneurship

Today I am Co-Founder, CTO, and COO of Molly’s Grape & Citrus Company. I also founded AgroLytics, Iris Automation, and Mangrove Publishing. My work has included industrial automation, software integration, food-company operations, and publishing. In 2021, CMURC named me its Entrepreneur of the Year for AgroLytics. AgroLytics was also named the 2021 Midland SmartZone Business of the Year and recognized at the 2022 Michigan Celebrates Small Business gala.

Writing

I write science-grounded thrillers, historical fiction, and practical nonfiction based on my engineering experience. I began writing seriously in 2025, and I approach it as a career, not a hobby.

Outside work

Family, music, sports, and history.

I spend as much time as I can with my family. I follow the Detroit Tigers and Detroit Lions, listen to vinyl, enjoy live music, and read widely—especially American and Michigan history. I also spend time learning about my own family history. I enjoy good beer and bourbon, handcrafted things, and people who care about doing their work well.
