We are passionate about advancing the science of tissue repair and regeneration.
That’s why we’re the driving force in the design, development and manufacturing of advanced collagen and mineral based medical devices that support the body’s natural ability to regenerate.
Through our proprietary technologies and innovative products, we’re striving every day to exceed the clinical demands of Dental, Spine, Orthopaedic, Dural Repair and Nerve Repair applications.
Since our inception in 1997, Collagen Matrix has been awarded significant grant money for the research and development of collagen based matrix products. We have expanded into two facilities with nearly 200 employees and have commercialized over 50 medical devices for our five business units – Dental, Spine, Orthopaedic, Dural Repair and Nerve Repair. Our products are now distributed around the world via a substantial global distribution network.
Our two facilities are situated in New Jersey, USA. The Corporate Headquarters and Manufacturing site is located in Oakland and the second Manufacturing facility is located in Allendale. These locations provide ample manufacturing capacity to support upcoming new product launches and anticipated expansion.
The evolution of the company’s leadership, proprietary technologies, design capabilities, manufacturing expertise and product portfolio has established a solid foundation for continued growth.
