Chanel Meredith | Program Director | chanel@bbbsjc.org 

Chanel has lived in Iowa for most of her life and graduated from the University of Iowa with a BA in Psychology and a minor in Human Relations. She has been with Big Brothers Big Sisters of Johnson County for almost 19 years – the first 17 years as a Mentoring Specialist and the past two years as Program Director. What Chanel loves most about her job is being able to watch the relationships between Bigs and Littles grow and develop over time – sometimes over many years.  She always loves seeing matches at events and having the opportunity to catch up with them, especially now that she is Program Director. Chanel is married with three children (including twins!) and a dog who all keep her very busy.   In her “spare time,” Chanel loves to watch her daughter perform in dance and Show Choir, and her sons compete in their many athletic activities.

Molly Gilroy | School-Based Mentoring Specialist | molly@bbbsjc.org

Rumor has it Molly was born and raised a Hawkeye, but details are sketchy. All we really know about her is she loves Harry Potter and there's a strong possibility she is an undercover secret agent. We could tell you more, but not without risking your safety. Just return Molly's calls, and we're fairly confident you'll be okay. ;)
