Kristy Riordan
Director of Research & Evaluation

Tell us about your career path. What were you doing before Ripple Effect? 

After years of studying and training to be a teacher, I realized I cared more about social science and big-picture policies that affect lives, rather than being the one teaching reading and math. So, I switched gears. Before Ripple Effect, I worked for the Army and evaluated behavioral health programs. 

What’s a hobby of yours? 

I am an avid reader, especially Stephen King novels. It’s hard to find the time with three kids, but getting to read on vacation or on an airplane is when I’m the happiest. 

Why is Research and Evaluation so important to what Ripple Effect does? 

If you aren’t willing to look at yourself and see how you can improve, you probably aren’t approaching your business in a way that has fidelity. The government hasn’t always done this well, but we do! So, we help clients measure, analyze, and better understand how to improve and learn from past mistakes.  

What is a funny quirk about you that people might not know? 

I’m a big germaphobe. Being a health researcher doesn’t help that.

Advice you would give a young professional? 

What my father always told me: You are going to work for the vast majority of your life, so do something you can take pride in and enjoy doing.
