Thielsch Engineering is a 500+ person engineering firm made up of many unrelated engineering divisions. I sold my engineering firm to them and we became their 13th division; their first “buildings” division and I stayed on for 3 years to help establish the new division. My division grew from a staff of 11 to 17 and became a multi-discipline firm by the time that I actually retired. I only have great things to say about Thielsch Engineering, Inc. and their President and CEO, Thomas E. Lent.


Kleinholz Inc. is a consulting engineering company that specializes in product development, mission critical facility consulting, and general electrical forensic engineering services including expert witness work.

The founder, James R. Fink, PE has technical, business and interpersonal abilities. Those skills aren’t always standard equipment on engineers. His clients benefit from Jim Fink’s 20 years of diverse electrical and mechanical engineering experience, but they also frequently remark on the eloquence of his delivery and the refreshing simplicity of content. As a client you can expect your project will be addressed with technical rigor, filtered with a common sense of business, and expertly communicated.

I have worked with Jim and respect him both professionally and personally.


“Consulting engineers are individuals who, because of training in one or more engineering specialties, are licensed professional engineers in private practice. They serve private and public clients in ways ranging from brief consultations to complete design and coordination of projects. They are often the technical liaison between architects, process specialists, contractors, suppliers and the client. A consulting engineer can provide general consultation, feasibility reports, design, cost estimates, rate studies, project development, patent assistance, and preparation of environmental impact statements.”

Those who offer their services to the public as an engineer are required to be licensed as a “Registered Professional Engineer.” Each state’s board has its own governing rules, but the same national tests are administered in each state. Basically, the requirements are as follows:

  • Be a graduate of an ABET-EAC accredited engineering program of four (4) years or more.
  • Pass an eight (8) hour written examination called the “Fundamentals in Engineering” (FE) examination.
  • A minimum of four (4) years of experience in engineering work working under the supervision of a Professional Engineer.
  • Pass an eight (8) hour written examination called the “Professional Engineer” (PE) examination in the principles and practice of engineering.

Some boards modify these requirements, usually based on experience. Most allow candidates to take the “fundamentals” exam in their senior year of college while the calculus, chemistry, etc. are still relatively fresh in their memory.

To qualify to take the PE exam, it is important that there is a professional engineer at your place of employment who is willing to “certify” that your experience in engineering work was “of a grade and character which indicates that you may be competent to practice engineering.”
