Personal

I am married and have three children, and my favorite thing in life is spending time with my family.  When the weather is warm here in Michigan, I also try to golf, brew beer, and get outside whenever possible.  In the fall I enjoy watching Michigan State football, and in the winter I try to work as much as possible so that I can enjoy the warmer weather when it arrives. My education, credentials, and professional accomplishments are listed below:

Professional Experience I first began working as an engineering co-op while I was a student at Kettering University in 1996.  I worked for one of the world’s leading automotive suppliers.  My work in the automotive industry covered a vast array of technical fields, including design, manufacture, plastic thermoforming, metal machining, failure analysis, heat transfer, metallurgy, sheet metal forming, machine vision, and basic electronics. After graduating from Kettering University I worked as a design engineer at a Michigan-based water heater manufacturer where I helped design and develop some of the industry’s most energy efficient tank-based water heaters.  I then enrolled in law school as a full-time student in 2003. After graduating from law school, I took a position as an associate patent attorney with a small firm in the metropolitan Detroit area.  I spent some time litigating patent, trademark, and copyright cases, but found that what I really enjoyed doing was representing clients before the U.S. Patent and Trademark Office.  I worked at that firm for 7 years before taking my practice back to Grand Rapids, Michigan and opening my own law practice in 2014.
