Zac Medley, PharmD 

With experience behind the counter dating back to 2003, Zac had always had an interest in people’s health and wellbeing. He found himself in the Cookeville area because of his schooling at Tennessee Tech University at which time he fell in love with the town and always planned on settling in the area after graduating with a Doctor of Pharmacy degree from Mercer University.

When Zac isn’t filling prescriptions, he enjoys exercising, running and staying fit and healthy. He also enjoys football and the occasional trip to the lake with friends. Go Vols!

Lauren Gibson, PharmD

Lauren’s passion for pharmacy began in April of 2007 when she was just a sophomore in high school. While working as a cashier at a local hometown pharmacy, she began to understand the health needs of the people she met daily. Within a couple of months, she knew that she wanted to become a pharmacist.

After attending Tennessee Tech University, she enrolled in pharmacy school at Samford University in Birmingham, Alabama. She ended up receiving a Doctor of Pharmacy degree and returned to Tennessee to make her home in beautiful Putnam County.

When Lauren is not filling prescriptions, she and her husband are watching ball games, exercising and enjoying time with their two dogs and two cats.
