Company Summary

Sierra Sciences is a company whose goal is to develop a medicine to prevent and/or reverse human cellular aging, an underlying cause of many diseases, as well as aging itself. We intend to do this by developing a medicine that will induce expression of the telomerase enzyme. Telomerase functions to extend the length of telomeres, which are sections of chromosomal DNA whose length controls the aging process.

    William H. Andrews
    President and CEO

    Dr. Andrews led the research that discovered human telomerase while Director of Molecular Biology at Geron Corporation from 1993 - 1997. He was awarded 2nd place as "National Inventor of the Year" in 1997 for this discovery. Dr. Andrews has worked in the biotech industry for 28 years as a cancer researcher. He has focused the last 15 years on reversing telomere shortening to increase lifespan, healthspan, and prevent/fight cancer.
