I've been working in learning environments since my freshman year of college, when I joined an all-boys adventure camp in North Carolina as a counselor. A Louisiana transplant, I am excited to be part of the BISC learning community, based in such a vibrant, diverse city.

I've been working in learning environments since my freshman year of college, when I joined an all-boys adventure camp in North Carolina as a counselor. I spent four summers there, facilitating a ton of activities for campers. After earning my degree in International Trade & Finance from Louisiana State University, I began searching for my next home, which landed me in Chicago. I was pleased to join the BISC community in 2014!

Growing up in Louisiana, I had the opportunity to live in a vibrant and culturally rich community. When I was looking for my post-graduation home, Chicago stood out. The diversity of the city is reminiscent of where I grew up (minus the snow). Outside of work I like to spend my time connecting with nature – camping, hiking, biking, swimming, etc. I have recently found interest in horseback riding and woodworking. I also enjoy visiting new cities – seeing how they work and enjoying all the food they have to offer.
