Fun Facts

What’s something intriguing that most people wouldn’t know about you?
I originally began my college career enrolled as an architecture major because I was intrigued by being able to use the creative part of my brain to find solutions. I am a visual learner who loves creative problem-solving. I ended up changing my major because I found the technical classes to be so boring and I felt a career in accounting offered a wide range of career opportunities with the ability to choose my own path, which led me to Wiss where I get to use the creative part of my brain every day!
