We at G&H thank you for taking the time to visit our website and hope at some point we can get to know you as a customer and friend.

Since acquiring G&H in 1983, Janan and I have dedicated the company and ourselves to working with our customers as though we too are employees for that customer. Everyone here takes a very personal interest in the customer’s success with respect to our contributions – no matter how small or how large. I honestly believe this dedication is what separates us from other shops.

G&H is committed to advancing technology. We have invested heavily in the most sophisticated laser cutting equipment available and remain one of the largest users of tubular laser equipment in the U.S. We have expanded our capabilities to include state-of-the-art CNC tube bending, and have invested close to $1 million in the most advanced robotic welding cells available. When you combine these assets with the knowledge and dedication of our professional manufacturing engineers and staff, you have capabilities that rival that of much larger manufacturing companies.

Finally, G&H is a company dedicated to Christian principles. Since 1983, Janan and I have done our best to find and retain people who will give our customers an honest day’s work and put their very best foot forward. We all understand that honor and reputation are our most valuable personal and corporate assets, and we will do whatever is required to protect them. In short, we believe God has blessed us with the opportunity to serve our customers, and we will do everything in our power - and with His - to earn the trust of our customers.
