Get to know our staff


Amber DeVries

Amber has been with ENCORE Research Group since 2007 and along the way she has acquired many hats. She is the site manager, a clinical research coordinator, the office party planner, and a birthday card making committee of one.

Amber graduated with a degree in biology from Jacksonville University. While there, she played on the women's soccer team, and between games she met her husband Kyle, who pitched for the JU baseball team. She still gets such a kick out of soccer that she is currently coaching a team of 5 year olds.

If you think Amber isn’t occupied enough at work and play, she also stays busy with two active sons and a toddler girl!

She and her husband have 3 small children who keep them busy since they are all very close in age. She can’t start her day without a cup of coffee in hand, and enjoys spending time with her family, reading, and binging on HGTV shows to gather more ideas for her handy husband to continue to fix up their older home!
