Ryan Brassell


Ryan Brassell is the co-owner of NFT, a design and engineering firm that provides services and products for the nuclear and aerospace industries, and the co-owner of Golden Biohack. A man of many talents, he holds degrees in criminal justice, finance, information systems management, an MBA and a JD, and is an Usui and Karuna Reiki Master, as well as a certified hypnotherapist.

Helping his dad through his journey with frontal temporal dementia and his mom’s journey with cancer lead him to research and find several of the technologies now offered by Golden Biohack. Ryan’s wife and co-owner of Golden Biohack, Jessica, and their two sons Ragnar and Julian, are his reason for biohacking. Being able to spend more time with them is what drives him to do everything he can to train his mind, body, and spirit.


Jessica Brassell


Jessica Brassell was trained as a Registered Nurse working in oncology, surgical, psychiatric, and long-term care settings. Jessica enjoys helping people learn, succeed, and achieve. This drive help others was the basis of her goal of providing Golden Biohack’s amazing, efficient and effective modalities to a broader segment of the public.  As co-owner of Golden Biohack with her husband Ryan, the pair discovered their shared love of biohacking and now devote their work to this physical and online space attracting seekers such as yourself: individuals dedicated to becoming stronger, faster, smarter, and more resilient.
