Cannabis Sativa, Inc. announced that Rob Tankson, co-founder of PrestoDoctor, has been elected to its Board of Directors. Rob's passion for finance and tech drove him to leave Google for an opportunity in the cannabis space where he co-founded online medical cannabis evaluation service PrestoDoctor, a telemedicine business connecting patients with cannabis-friendly doctors in California, Nevada, New York, Oklahoma, and Missouri. Rob's efforts led PrestoDoctor to a multimillion-dollar valuation and acquisition by Cannabis Sativa in August of 2017. PrestoDoctor currently has over 100K patients across the country.
