Sierra Sciences

Sierra Sciences is a private Reno, Nevada biotechnology company focused on extending human lifespan and healthspan through telomere maintenance and telomerase induction. Founded by telomerase researcher William H. Andrews, the company concentrates on discovering compounds and related technologies intended to induce telomerase expression, lengthen telomeres, and counter cellular senescence associated with aging. Its public materials emphasize research rather than commercial drug development, and indicate that affiliated entity Sierra Holdings licenses discovered compounds and technologies to downstream product developers. Sierra Sciences appears to operate primarily as an early-stage longevity biotech and research platform company rather than a clinical-stage therapeutics developer.
