Our History

After 22 years of experience working through the ranks of the family business, founder Gerald W. Thiel set out on his own and began contracting with custom home builders in the fall of 1977. His name soon became synonymous with high-quality, custom work. G.W. Thiel, Inc. was born and his small crew began to grow, expanding to residential and commercial developments.

Throughout the company’s growth, Jerry remained dedicated to developing the craft of carpentry for future generations. By partnering with the Carpenter Apprentice Training Center, the company has supported the mentorship of young apprentices; teaching them lifelong skills and instilling them with the dedication to quality, safety and integrity that the company stands for to this day.

With the company’s foundation securely planted, Jerry passed the reins on to the next generation in 2005. A legacy of quality and commitment that has set the cornerstone for G.W. Thiel, Inc. now and well into the future.

Extra Mile:

  • Willing to do whatever it takes to get the job done.

  • Going above and beyond what is expected or would be asked of you.

On Time:

  • Honoring promises and commitments.
  • Your name is on it.
  • Be worthy of responsibility or trust, don’t make excuses.
