      Ever since I was young, I was always told I had a keen interest in how things work. In high school I was very interested in cars and automotive design, so my physics teacher suggested I become a mechanical engineer. I attended Missouri University of Science and Technology where I graduated with a minor in mechanical engineering in 2017, then went back to get a graduate certificate in contemporary structural engineering in 2024. I have worked in machine design, deck and structural design, and I am now working at DOTec on mechanical, electrical, and plumbing design as well as managing project bids.

      Outside of work, I am an avid reader and enjoy science fiction, fantasy, and true crime genres. I am a big fan of music (some might say fanatical) and I collect records and CDs of my favorite bands. I also am a self-taught drummer, guitarist, and bassist. I enjoy playing indoor soccer on a team with my brother (the Relapsed Gambling Addicts is our name, don’t ask) as well as playing golf or long-distance running. I am a proud member of the Sunday Morning Rugby Football Club out of St. Louis and enjoy playing both traditional rugby as well as the seven’s style (and the occasional game of touch rugby). I currently live in Affton, MO with my fiancée Kim where we enjoy walking in parks, taking care of our house, binging shows, and trying the newest craft beer or pizza place.

      “True Professionals”

      DOTec did the final design and engineer stamped drawings for my shipping container house. Based on my interface with them they were responsive to my needs and did a good. I have recommended DOTec to others, and will use them again should the need arise.

      “Great Solar Design”

      They were fantastic to work with. A manufacturer recommended them for my Solar/Structural engineering project. They quoted a fair price, met my difficult schedule and provided a quality set of design documents for the project. I have recommended them often and will work with them again soon.

      “Job Well Done”

      We would be able to use their services on our out of state projects as needed. They would provide us with engineered sealed drawings and calculations quickly. Thank you for a professional job done well.

      “Top Notch Service”

      Been doing business with Dotec for a long time. While we are a regular/repeat company our jobs are small potatoes compared to most but that has never stopped us from receiving top notch service. I have recommended Dotec to many and will continue to when I have the chance.
