Gabriel Aguero, DO

Hometown: Monument, CO

Medical School: Rocky Vista College of Osteopathic Medicine-CO Campus

Undergraduate: Creighton University

Career Plans: Combined Med-Peds Hospitalist

Favorite Aspect of Residency at MCW: The best part about MCW is that it is a large academic institution where we see a huge diversity of patients and populations, but the people still foster an environment of learning, support, and autonomy.

Favorite Aspect of Milwaukee: There's always something to do! Especially in the summer when MKE has festivals basically every weekend. There are also way more outdoor activities both in and around Milwaukee including single track biking and hiking than I would have expected. Considering the size of Milwaukee, we have a really amazing food scene! The Diplomat is a favorite of mine in the Lower East Side. 

One Thing You Must Try While Living in Wisconsin: Taking the ferry from Door County to Washington Island and biking around to all of the cool beaches and museums. They also have a lavender farm which hands-down had the best ice cream I've ever had (and I've had a lot).

Interesting Fact About Me: I'm a sucker for horror movies, especially the bad ones! Halloween is my favorite holiday, but horror movies are good year-round. Watching holiday-themed ones are also great; The Thanksgiving horror niche is a fave.

Medical School: Medical College of Wisconsin

Undergraduate: Marquette University

Career Plans: Hematology / Oncology

Favorite Aspect of Residency at MCW: My favorite aspect of MCW residency is the strong sense of community and support. From co-residents to faculty, I’ve felt consistently encouraged to grow not only as a physician but also as a person. The camaraderie and shared commitment to excellent patient care make this place feel like home.

Favorite Aspect of Milwaukee: Milwaukee’s got it all: amazing festivals like Summerfest, a killer food scene with gems like Stone Bowl Grill (South Korean cuisine), and affordable living that doesn’t break the bank. What’s not to love?

One Thing You Must Try While Living in Wisconsin: FRESH cheese curds. Ideally squeaky, fried, and with a side of ranch (I also prefer with original sriracha not "pretend sriracha)”. You will never look at cheese, or life, the same way again.

Interesting Fact About Me: I’m a self-proclaimed water sommelier. Catch me lurking in the grocery store’s water aisle, judging the vibes of each bottle like I’m at a wine tasting. Yes, I do think waters taste wildly different. No, I will not be taking questions at this time.

Undergraduate: University of Nevada, Reno

Career Plans: Academic Hospitalist

Favorite Aspect of Residency at MCW: The vibes are always high at our program! I am constantly running into residents, faculty and medical students that I have worked with in the past and have become friends with. Our I&O system lets you take time off for the important events in your life and really promotes wellness here. When the times get tough, ice cream rounds are a welcomed retreat; the Patio Cafe always has my back by serving up to six different flavors of ice cream until 3 a.m.

Favorite Aspect of Milwaukee: Milwaukee has the most vibrant and fun summers! Catch me at a Brewers game, Summerfest, German Fest or any of the numerous public golf courses and parks this summer. During the winters you can get cozy, watch the snow fall, and enjoy sipping hot chocolate.

One Thing You Must Try While Living in Wisconsin: Although cheese curds are the obvious answer, you have to get out to see Lake Michigan while you're here! Whether it's having a bonfire at the beach or cruising the coast on a bike ride, enjoying Lake Michigan is a beautiful part of the Milwaukee and Wisconsin experience.

Interesting Fact About Me: I own a wide variety of Hawaiian shirts including one of which I purchased at our very own VA.

Favorite Aspect of Residency at MCW: The people! I have made lifelong friends through residency, who make going to work daily truly enjoyable. This also extends to the many faculty and mentors who are so passionate about what they do and teaching daily.

Favorite Aspect of Milwaukee: Milwaukee summers are simply magical! There are tons of outdoor activities, festivals, nature walks, beaches, and lake front activities open to enjoy.

One Thing You Must Try While Living in Wisconsin: Kopps Frozen Custard!! Keep an eye out for the flavors of the day. My current faves are Banana Walnut Chocolate Chunk and Red Velvet Oreo.

Interesting Fact About Me: I love to travel and have been to 14 countries so far! Most recently, I went to Portugal and have been dreaming of Pastel de Nata ever since.

Favorite Aspect of Residency at MCW: Without a doubt, it’s the people. From my incredible co-residents to our supportive administration, dedicated faculty, and hardworking staff – everyone plays a role in fostering a culture of community, collaboration, and continuous learning.

Favorite Aspect of Milwaukee: I love that Milwaukee offers the energy of a vibrant city while remaining affordable. The city is alive with festivals, cultural events, and endless activities, all complemented by the natural beauty of Lake Michigan. Plus, just a short 30-minute drive in any direction brings you to towns with a rural feel and many outdoor adventures. Wisconsin is a stunning state, and Milwaukee blends urban excitement with natural charm.

One Thing You Must Try While Living in Wisconsin: I believe that Wisconsin's best kept secret is an area deemed the "driftless region." This stunning area is a blend of carved bluffs, rolling hills, and charming small towns. Whether you're camping, hiking, fishing, or canoeing the Kickapoo River, there’s no shortage of adventure. Be sure to explore local restaurants, cozy coffee shops, and hidden breweries along the way. It’s a slice of Wisconsin that feels like stepping into a postcard.

Interesting Fact About Me: Consider me your human GPS for Midwest outdoor adventures. Need a top tier mountain biking trail despite Wisconsin having no mountains? I’ve got you. Best archery range in a Milwaukee to bring out your inner Katniss? Easy. Just don’t ask me for directions – I can get you to the woods, but I can’t promise I’ll get you back out.
