Medical school: University of New Mexico

Undergraduate: University of New Mexico

I grew up in Portales, New Mexico, and completed my undergraduate and medical school at the University of New Mexico. When choosing a program, I wanted to find somewhere with a large catchment area to provide unique pathologies and challenging cases coupled with supportive faculty to help hone my clinical skills. When I interviewed with Mizzou, I knew this program would surpass my expectations. My husband and I knew Columbia would be a perfect fit. As soon as we arrived in Columbia, my husband and I found amazing friends, great food, and lots of activities that made us feel at home.

Medical school: Saba University

Undergraduate: Lewis and Clark College

I was born and raised in Los Alamos, New Mexico. After moving to Oregon for undergrad, I moved to the island of Saba in the Dutch Caribbean for medical school. I then spent the last two years moving around the US (to over five different states!) and rotating in various hospitals.

When selecting a residency program, it was important that I find a place where the residents and faculty were personable, knowledgeable, and supportive and where I could train and evolve into the emergency medicine physician I have always wanted to be.

After an afternoon of Zoom calls encompassing various topics such as ultrasound, my scuba diving endeavors, and my love for candles and fuzzy blankets, I knew Mizzou was where I wanted to train. Even over a computer, it was clear what Mizzou had to offer and that my strengths and values were recognized and appreciated. Mizzou is unique in its wide catchment area with a diverse population and provides excellent exposure to various pathologies.

Since arriving at Mizzou, I have found a home away from home. I am lucky to have made friends quickly and connected easily with the other residents. The faculty are eager to teach and provide feedback to help us learn and grow as physicians. When I’m not at the hospital, I can always be found with my husband and my newborn son — typically in the kitchen cooking and baking, hiking on the trails, or in our garden tending to our various plants

Medical school: University of Missouri - Columbia

Undergraduate: University of Missouri - Kansas City

I grew up in the small town of Warsaw, Missouri, and l have always cherished the values of community and compassion instilled by my small-town upbringing. After graduating from Lincoln High School, I moved to Kansas City, where I completed my undergraduate at the University of Missouri - Kansas City.

While in Kansas City, I worked as an ED scribe, where I discovered my passion for Emergency Medicine. This pivotal experience kindled a deep sense of purpose and a commitment to impacting the lives of those in need during critical moments.

I was accepted into the University of Missouri - Columbia School of Medicine through the Bryant Rural Scholars program. Being from a small town in Central Missouri, I’ve known that I wanted to practice medicine in this area, so I am very excited to be able to continue my training at University Hospital in Columbia and learn from the physicians providing exceptional care to people living in the heart of our state. While doing my Emergency Medicine rotations at Mizzou, I identified many attendings and residents with whom I share similar values. I knew this program could help me become the physician I’ve always dreamed of being. Additionally, I recognized the same sense of community and compassion within this residency program as the community I was raised, which made me more excited to spend the next three years training at Mizzou.

Outside of residency, I enjoy spending time with my family and friends. I have an amazing husband and two wonderful children, Calvin and Josephine. At any given time, you’ll find us watching sports (we’re a Royals/Cardinals divided home, but Go Chiefs!), gardening, playing outdoors, or enjoying some great food.

Medical School: A.T. Still

Undergraduate: Rockhurst University

I was born and raised in St. Louis, MO. I then went to Rockhurst University in Kansas City, MO, and ended up at A.T. Still in Kirksville, MO, for medical school. Naturally, I chose a different Missouri city for my residency, Columbia. In reality, I chose the University of Missouri because of the people in the program and the multitude of learning opportunities the program has to offer. During my interview, I could tell the faculty and residents had more than just a working relationship; they enjoyed being around each other outside of the E.D. Mizzou’s program offered everything I was looking for: it is an academic center with a level 1 trauma center, has a very diverse patient population, and has faculty that genuinely cares about the residents’ success. I enjoy spending time with friends and family, golfing, and watching football in my free time. MIZ-ZOU!

Medical School: University of Kansas  

Undergraduate: Truman State University

I was born in Massachusetts to a military family, but my family settled in Missouri at a young age. I grew up in Auxvasse, MO, a rural town near Columbia. That being said, I was familiar with Columbia before starting residency. Between undergrad and residency, I spent seven years working and living in Kansas City, where I attended medical school at the University of Kansas School of Medicine. I was fortunate to have the opportunity to rotate at Mizzou as a visiting student before matching. During my away rotation, the department faculty were all very welcoming, from the EM attendings and residents to the EM administrative staff. They even went out of their way to arrange my schedule so I could have consecutive days off to return home and visit my wife, who was pregnant with our twins at the time. My wife and I were excited to return to Columbia for my residency. Columbia is close to family for us and an area with a lot to offer. As a college town, it’s a perfect size community to raise a family, with unique local businesses and beautiful outdoor spaces (like the MKT trail). In my free time, I like lifting weights, going on coffee dates with my wife, traveling, running with my dog, riding bikes, and competing in ultra-endurance events.

Medical School: A.T. Still

Undergraduate: Drury University

I was born in Minnesota but moved to Warrensburg, Missouri, at an early age. I grew up involved with my local community, playing sports, and participating in multiple service clubs. I then went on to undergrad at Drury University, where I also played baseball. I then attended medical school at A.T. Still University in Kirksville, Missouri, where I spent my didactic years. I was based out of Christian Hospital in north St. Louis for clinical. During my interviews, I sensed a strong sense of community, passion, and dedication in this program. I loved the idea of being heavily involved in a rural Missouri community again, with ample opportunities to work at nearby Moberly and Jefferson City. The residents and attendings were open, candid, and compassionate. The experience and background of the attendings were diverse, from people with academic or community backgrounds to people many years into practicing and some fresh out of residency. My fondness for these things, the ability to stay close to family, and the ample opportunities present after completion made choosing Mizzou abundantly clear.

Medical School: Saba University School of Medicine

Undergraduate: North Carolina State University (Go Pack!)

My name is Alexander Hamilton (yes, like that guy on the bills). I am originally from Canada but completed my undergraduate in North Carolina and now call Ponte Vedra Beach, FL home. I am a former college student-athlete and still enjoy swimming, golfing, and football. Outside of the hospital, my hobbies include reading, skiing, days on the beach/lake, and spending time with my family and our dogs. My academic interests include trauma, resuscitation, procedures, and critical care. When looking for where I wanted to complete my residency, I was looking for a program that offered a family feel, placed a lot of importance on creating well-rounded and effective residents, and had a strong trauma/resuscitation curriculum/patient population. I was looking for a site that was not a large city yet not in “the sticks.” Columbia fits that bill, and I love the college town vibe. I knew that Mizzou was the place for me after interviewing (via Zoom) and meeting the attending, residents, and support staff. Their passion, energy, and dedication to teaching ultimately led me to call Mizzou home for three years.

Medical School: University of Missouri – Columbia 

Undergraduate: Brigham Young University

I grew up on a farm in rural Northeast Missouri. After high school, I lived in Mexico (the country, not the city in Missouri) for two years before moving out West for undergrad. I then returned to Mizzou for medical school and have enjoyed Columbia's safe, small-town vibe.

During my rotation in the emergency department, it was clear the attendings were deeply invested in my success and were excited to help me improve as a future physician. Interview day solidified my thoughts on the program, and I knew Columbia would be a place where I could thrive. I am happy to stay in CoMo and look forward to developing the amazing relationships that began during my rotation.

I enjoy hunting and fishing, baseball, and traveling with my family in my free time.

Medical School: University of Missouri – Columbia

Undergraduate: High Point University, High Point, NC

I grew up in Washington, MO, before deciding to branch out and attend college in North Carolina, where I majored in biology and minored in Spanish. I also worked in a nursing home as a CNA, where I truly gained an appreciation for what a team sport healthcare is. After college, I worked for a year as an ER tech, where I first fell in love with emergency medicine. I attended Mizzou for medical school and loved every opportunity to work with the ER residents and see what a tight-knit group they were. In my free time, my boyfriend and I enjoy spending time with our three dogs, grabbing a beer at Logboat or biscuits at the Ozark Mountain Biscuit Co., hanging out with friends, or binge-watching a good show.

Medical School: Rocky Vista University College of Osteopathic Medicine - Ivins, Utah

Undergraduate:  Truman State University

I grew up in a small community near Peoria, Illinois, and have always loved being outside. Traveling to Utah for medical school was a once-in-a-lifetime opportunity I will forever be thankful for. I combined my love of nature with my love of medicine through Rocky Vista’s Rural and Wilderness Track. While searching for a residency program, my husband and I had our hearts set on Mizzou EM. We spent many date nights in Columbia eating at Seoul Taco and rock climbing at Capen Park, so matching at Mizzou felt like coming home. I’m excited about Mizzou’s EM program because it combines the best of high-acuity care with opportunities for rural work. The faculty and staff have been incredibly supportive, and I look forward to continuing my training while exploring the mid-Missouri wilderness!

Undergraduate: University of Nebraska

Hello everyone; I’m Alex Tagart. I was born and raised in Nebraska (Go Big Red!). I wanted to stay in the Midwest for residency training, and at the same time, my wife and I were looking for a new adventure. We loved the idea of moving to Columbia for my residency training and were ecstatic when we learned where I matched! Everyone in the program made me feel right at home. One thing that stood out to me was the family atmosphere in the Emergency department; everyone was friendly and had each other’s back. Since our time in Missouri, my wife and I have enjoyed taking our dog, Frankie, on walks through new hiking trails and have loved trying the different restaurants here. I enjoy flying, weightlifting, magic tricks, and watching new movies in my free time. I’m also a big sports fan and look forward to having another college team to root for!

Medical School: Edward Via College of Osteopathic Medicine - Auburn Campus

Undergraduate: University of Missouri - Columbia

I was born and raised in Lebanon, MO to Mizzou parents. I naturally followed the path and was a biochemistry major at Mizzou for undergrad. For medical school I traded in Truman for Aubie because I’m a Tiger at heart. My wife and I moved to Auburn, AL for medical school and then we got the opportunity to move back to Columbia with our own future Tiger. Being a girl dad is my personality and favorite pastime, but I also love anything that gets me outside with my fur baby and family. Mizzou sports, playing ball with my dog, and lots of walks are how we spend most of our days.

Medical School: Ross University School of Medicine

Undergraduate: Kenyon College

I was born in North Dakota but grew up in the Chicagoland area. As a child and young adult, I moved around quite a bit. Including Missouri, I have lived in 13 states, which likely sparked my love for travel. I have now also visited 11 different countries. Before attending medical school, I advanced in pre-hospital medicine, spending the last few years as a flight paramedic. This experience has significantly influenced my aspirations as an Emergency Medicine physician. When it came time for residency, I sought a program that offered exposure to Level 1 medicine and trauma, as well as opportunities to work with rural and underserved populations. Additionally, I wanted experience in EMS and medical direction. All of this is at Mizzou and is guided by faculty committed to helping me become the best EM physician possible. Additionally, after speaking with residents and reviewing program statistics, I was impressed by the program's success in placing graduates into fellowships nationwide.  When not in the hospital, I continue to enjoy traveling and exploring as well as running, biking and flying.

Medical School: University of Missouri - Columbia School of Medicine

Undergraduate: Missouri State University

I’ve lived in Missouri my whole life, growing up in rural southwest Missouri in Marshfield, going to Missouri State University in Springfield for undergrad, and coming to medical school here at Mizzou. Rotating with the department during my fourth year confirmed that this was where I wanted to do residency. The program has a really collaborative atmosphere, the faculty and senior residents are always up for teaching, and the program as a whole is committed to our education and growth. When I’m not working, I love to hang out with my friends, family, and cat, eat too many sweets, read, and cheer on our basketball team in my free time!

Medical School: University of Missouri - Columbia School of Medicine

Undergraduate: Missouri State University

I’m a small-town kid, raised in Dexter, Missouri. Coming to Mizzou for medical school, I found Columbia to be the perfect size. It has the amenities of a city while still offering the close-knit community feel I loved growing up. During my fourth-year emergency medicine rotation, it was a no-brainer to stay here for residency. The faculty are top-notch and genuinely invested in teaching and shaping residents into confident, capable EM physicians. Seeing how prepared and skilled the PGY-3s were during my sub-I, combined with the high acuity cases we see as a level one trauma center with a large catchment area, confirmed that this was the place for me. In my free time, I enjoy staying active, spending time outdoors, hanging out with my wife and our 5-year-old German Shepherd, reading, and cheering on Mizzou football in the fall.

Medical School: Chungnam National University College of Medicine

Undergraduate: Hanyang University

'Growth Mindset' was the key word that neatly captured both this burgeoning program and town, and my journey to the U.S. graduate medical education. Initially not knowing much about CoMo and the culture, I did not know what to expect as a city guy from Seoul, South Korea who seldomly drove cars to get around. However, it turns out that both the program and the town are growing—New rotations, new children's hospital and birthing center, and even a Trader Joe's soon to open. This mindset is very familiar to South Koreans like me who are geared toward new challenges and opportunities for growth which has powered the economic rebuilding of the country since 1953.

About me, I used to work at a semiconductor fab as an EHS professional before entering medical school and studying for the USMLE. My current pastime activities include running and noncompetitive swimming for fun. FYI, I am not a K-pop or K-drama expert at all—Previous career and medical school ​gave me no time for them—but will be happy to talk at length about its society, politics, and history

Medical School: Olivet Nazarene University 

Undergraduate: University of Illinois - Rockford, IL 

I was born and raised in Galesburg, Illinois. I attended college at Olivet Nazarene University where I majored in biology. Prior to medical school, I was a CNA which is where I learned the foundations of patient care. I then completed medical school at the University of Illinois in Rockford, IL as a part of their rural medicine training program. When applying for residency, Mizzou caught my eye because it offered everything that I was looking for in a residency program: camaraderie among the residents, excellent training in trauma, rural exposure through the large area that the hospital system serves, and strong female leadership. It is an added perk that my husband is a urology resident here! We believe that Mizzou was the best fit to train us to serve rural populations without strong access to healthcare. In my free time I love to run, travel, try new coffee shops with my husband, and spend time with my family, which includes my dog Milo!

Medical School: University of Missouri - Columbia School of Medicine

Undergraduate: University of Missouri - Columbia

I’m grew up in Champaign, IL which is very similar to Columbia in a lot of ways. I moved to CoMo to go to Mizzou for undergrad and have been in this town ever since. I chose to do residency at Mizzou because our faculty is obviously interested in pushing us to be the best physicians we can be. They provide us with resources, encourage independence, and provide excellent teaching on and off shift. In my free time, I love to read and crochet.
