They support our development efforts as if they are part of the internal team and their level of communication is superb.

GGI has been essential to product success and bringing the highest possible quality devices to the customer. They take on real challenges and work to solve them, not only with highly precise machined parts but with a range of processes and capabilities.”

Sr. Design Engineer,

Large Medical Device OEM

“I wanted also to share that if I am ever asked to rank all of the vendors I have worked with according to responsiveness, achieving goals, communication, skill, and overall medical product knowledge, GGI wins, hands down. It is a pleasure seeing the project turn into a trusted process. Thanks to you both and your team!!!!”

Design Assurance Engineer,

Large Medical Device OEM

“Over the past several years GGI has worked with my project team to develop components for multiple innovative new devices. The complex nature of our designs makes these projects challenging and require a lot of personal attention, crisp communication, and creative problem-solving to meet our project targets of timing, cost, and superior quality. GGI has demonstrated their willingness and ability to deliver in these areas, making them a valued partner for our business.”

Director of Advanced Instruments

Large Medical Device OEM

“GGI’s project management support is the best of any MIM house we have worked with. We are confident when placing a new tooling PO with GGI that we are going to close the project on time. When we get into production, GGI partners with us to continually improve the process and cost over time. We ask GGI to help us compete and they are always there looking for new ways help us to advance.”
