Sheri Madison brings more than 25 years of experience as a civilian law enforcement professional, retiring in 2018 as an Intelligence Supervisor with the Kentucky State Police. Her career focused on narcotics and special investigations, specializing in call detail records, digital evidence, social media, and enterprise-level case development, with a strong emphasis on producing intelligence that holds up in court.
After retiring from KSP, Sheri worked as a Penlink contractor before joining a HIDTA task force in Central Kentucky, supporting long-term, multi-agency narcotics investigations. She joined Penlink full time nearly two and a half years ago, moving from inside sales into training. Today, she draws on her investigative background to help agencies apply technology strategically, verify intelligence, and build stronger cases.
