Sierra Neuroscience Institute

Sierra Neuroscience Institute is a private U.S. neurosurgery practice focused on advanced brain, spine, and neurovascular care in the Los Angeles area. The organization markets fellowship-trained specialist services spanning brain tumors, minimally invasive and complex spine surgery, cerebrovascular surgery, and endovascular neurosurgery. Public-facing materials emphasize personalized care, multidisciplinary management, and use of technologies such as neuronavigation and robotics in surgical practice. Available evidence indicates it operates as a clinical healthcare provider rather than a drug-development biotech company, despite some third-party databases linking it to the historical name Sierra Neuropharmaceuticals. The institute appears to be commercially operating with offices in Glendale and Los Angeles, California.
