Our History

Founded on the belief that our best friends deserve better

Our founder, Aaron Hirschhorn, created Gallant after experiencing the power of regenerative medicine for himself. He suffered from a debilitating back injury and traditional surgeries and injections proved unsuccessful. So Aaron underwent a single stem cell treatment and the results were life-changing in more ways than one.

As a dog lover, Aaron knew that our best friends could also benefit from this revolutionary approach to healing. He partnered with Dr. Linda Black to make it a reality. They created an innovative service that allows pet owners to harness the power of regenerative medicine by banking their pets’ stem cells for the treatment of future health issues. They also applied the science of regenerative medicine to developing new treatments for debilitating diseases in pets.

Independently Funded

In perhaps our highest-profile funding effort, Aaron appeared on Shark Tank in 2019. But the company has also secured funding from some of Silicon Valley's most savvy investors and venture capital firms. Companies such as BOLD Capital Partners, Digitalis Ventures and Maveron have invested in Gallant and are helping us change the future of veterinary medicine.

Our Future

Sadly, we lost Aaron to a tragic accident in 2021. But his legacy lives on in the work we do and in the lives of the animals we help. We’re committed to moving forward and investing millions in research and development for the future of regenerative medicine for animals.

Gallant Labs

Gallant’s state-of-the-art 8300-square-foot headquarters is located in the La Jolla area of San Diego, California. Our facility includes a cGMP manufacturing suite, quality control, research and development laboratories and facilities to support clinical product manufacture, storage and shipment.


We’re a collective of respected veterinarians, scientists, and some unbelievably dedicated entrepreneurs. Our work is the result of over 100 years of regenerative medicine experience and a commitment to invest millions in the future of stem cell therapies for animals.
