An avid learner and a brilliant self-taught programmer with more than 10 years of IT and software development experience, Brent has a voracious appetite for knowledge and an overloaded bookshelf.

Brent is a Pittsburgh native and a semi-pro hockey player. He enjoys brewing up a batch of craft beer, travelling with his wife, and eating authentic Mexican food.

Leslie Sage

Data | Adoption

Leslie is a data scientist with a passion for data. And science. Leslie performs data magic tricks to help new clients structure their information, then builds and optimizes a DevResults site to fit their needs. She trains clients in data management and makes sure they can organize the info they need to make informed decisions.

Leslie worked with the Obama Presidential Campaign in 2012 as Deputy Data Director for the battleground state of Iowa. In that position she transformed Red Bull into winning voter models, created up-to-the-minute dashboards for decision-makers, and discovered Midwestern craft beers.

Leslie holds a Ph.D. in Microvascular Physiology at the University of Bristol in England. Her research took her to the Hospital for Infectious Diseases in Ho Chi Minh City, Vietnam, where she collaborated with the Gates Foundation and Oxford University to develop a new way to study dengue infection.

Outside of work, Leslie enjoys hot weather, roller derby, NPR, brunch, and several other mealtimes. And tacos.

Josh Mandell

A proud father of twins, Diego lived all of his life in Argentina and speaks Spanish and English fluently, plus a bit of Hebrew and Mandarin, and he's currently learning Catalan.

When he’s not crunching code, you’ll find him at the park with his girls, making an asado for his friends, playing fútbol or hitting the strings of his SG.
