I'd pick Millikin a hundred times over. My supportive and invested faculty, amazing Greek experience, quality education, vast career and organization opportunities made my college experience nothing short of incredible. That's not to say I didn't think the caf food was gross sometimes, or policies were occasionally unfair, or that classes weren't difficult -- that's something that comes with most colleges -- but my overall experience was phenomenal and the great outweighs the occasional negative experience.
I especially love the small campus size; it was great to know nearly everyone on campus and have such expansive friend groups. It also made the opportunities for leadership, internships, and special opportunities more attainable since there is less people to compete among. Although a larger school might have a more recognizable name, lack of internship experiences and difficulty getting letters of recommendation (which is common in D1 size schools) will not help you move forward into graduate school or the profession of your dreams.
My Greek experience was phenomenal and left me with lifelong friendships, leadership experiences, networking opportunities, and truly allowed me to find myself as a person. I lived in the sorority house for just one year, but it was an absolute blast, incredibly supportive, and exactly what I needed to learn to come out of my shell and diversify my friend group. I never thought I'd join a sorority but now I'd recommend going Greek to anyone -- the worst that could happen is that you find out it's not for you.
Safety is the only clear negative at Millikin. Generally speaking, you are very safe on campus, but Decatur is a bit of an armpit. I've found that this is actually very common in most college towns so you'll experience it no matter where you go. I never had bad experiences but I always walked in groups, carried mace, and took safe rides when needed. There's no shame in being safe.
5/5 stars, would recommend Millikin!
