Cody Baker, M.D.

Undergraduate: Missouri State University
Medical School: University of Arkansas for medical sciences

Baker, CodyHello! I was born and raised in Rogers Arkansas. I was involved in football and basketball throughout high school. Upon graduation, I decided to come to Missouri where I attended Missouri State University in Springfield. I studied biology and psychology and worked as an ER tech at Mercy Hospital. This was my first exposure to Emergency Medicine and quickly fell in love with it. I went back to Arkansas for medical school where I trained in both Little Rock and Fayetteville. I am very excited to now be living in the wonderful city of KC and training at UMKC/TMC. My hobbies include weight training, running, biking, fishing, kayaking, and backpacking. Beyond excited for these next 3 years!
Christopher Erikson, D.O.

Undergraduate: Luther College – Decorah, LA
Medical School: Kansas City University of Medicine & Biosciences College of Osteopathic Medicine

Chrisopher Erikson, D.O.Born and raised around the Minneapolis, MN area, I grew up ice skating, snowboarding, and frequently uttering the phrases “sohry,” “ope,” and “oh yah.” After graduating high school, I decided to venture far, far away to attend Luther College in Decorah, IA. Luther provided some of my most formative years, as I worked hard playing baseball, and studied hard for a dual degree in Biology and Chemistry. After graduating, I moved down to Kansas City where I went to medical school at Kansas City University of Medicine and Biosciences. Over the years, Kansas City has truly grown on me, and the exceptional reputation of Truman’s Emergency Department made it an easy choice to stay here for residency. Even after living in KC for four years, I continue to discover new things on the regular. Some of my favorite activities include attending and tailgating at Royals games, eating at Nara Sushi, paintballing in the caves at Jaeger’s, discovering a new rooftop bar, attending concerts at the Midland, rock climbing at ROKC, and treating my friends and family to Arthur Bryant’s BBQ.
Ryan Krempels, M.D.

Undergraduate: University of Wyoming – Laramie, WY
Medical School: Creighton University School of Medicine

Krempels, RyanI am a Wyoming native and grew up in Cheyenne, WY. After high school, I attended North Idaho College on a soccer scholarship before transferring to the University of Wyoming to finish my bachelors. After undergrad, I married my high school sweetheart, Erin, and we both moved to the flat lands of Nebraska so that I could attend Creighton University for medical school. Even before med school, I was always interested in EM and after rotating at Truman, it was clear that this was a perfect program for me. I felt immediately at home with all of the attendings and residents and loved helping to take care of the underserved patients that Truman serves every day. Outside of the department, you can find me running with our lab, Bridger, or checking out one of Kansas City’s top-notch breweries with my wife while we plan our upcoming ski/fishing/hiking/international travel trips.
Peter Lampe, M.D.

Undergraduate: University of Missouri – Columbia
Medical School: Creighton University

Lampe, PeterI was born and raised in St. Louis, MO. I went to Mizzou for undergrad, but returned to St. Louis after graduating to work as a scribe in the ED. I then moved to Omaha to attend medical school at Creighton University. This is where I met my future wife, Kenzie! We were excited when I matched at UMKC for a number of reasons. The EM program is well established and provides excellent training for their residents through its diverse patient population, procedures, traumas, and supportive staff. When I am not in the ED, I enjoy playing soccer, fly fishing, exercising, listening to podcasts, and rooting for the St. Louis Blues and Cardinals.
Jonathan Lyons, D.O.

Undergraduate: University of California Los Angeles
Medical School: Kansas City University

Lyons, JonathanI grew up with four awesome siblings in beautiful Southern California enjoying everything that the West coast has to offer. I attended UCLA for undergrad where I worked for UCLA EMS. I chose Emergency Medicine for the varied pathology and because I enjoy thinking about and caring for critically ill patients. I look forward to the strong training opportunity that Truman Medical Center has to offer. In my free time I enjoy being choked in a padded room while wearing pajamas (translation Brazilian Jiu Jitsu), finding excellent mountain biking destinations (1. Moab 2. Sedona 3. Fruita), searching for the best Taco Tuesday restaurants, going to the gym without posting selfies, window shopping for dogs, and when I can put together more than a few days off in a row I love to travel with my wife who always has an idea for our next adventure. If I were not in medicine, I would definitely be working at a bike shop in a scenic small town.
Brian Opferman, M.D.

Undergraduate: Loyola University Chicago
Medical School: Loyola University Chicago Stritch School of Medicine

Opferman, BrianI was born and raised in Tinley Park, Illinois, a southwest suburb of Chicago. While studying Biology at Loyola University Chicago, I took that time to fully embrace all that Chicago had to offer in food, drinks, and attractions. I also received my first exposure to Emergency Medicine as an undergraduate working with student EMS on campus. There really was no greater thrill than cruising through campus in a golf cart, hazards flashing, and running in to help the intoxicated freshmen. I enjoyed this experience so much, that I took my EMT-B license and worked for a private ambulance company in the Chicago suburbs during my gap year. Maintaining that Rambler pride, I further explored the field and the city at Loyola’s medical school. I chose UMKC for a number of reasons. The patient population and training environment at Truman Medical Center provides the perfect mix between a county ED and academic institution. I had never been to Kansas City before, but immediately fell in love with the city vibes without the city hassles. In addition to training and location, the UMKC faculty and residents welcomed me with kindness and laid back conversation. I am a Chicago sports fanatic, but will make room to embrace the sports culture of KC. I plan to spend whatever free time I have in the coming years exploring the city, running/playing sports, bingeing the latest thrillers, and forming an informed opinion in the “Best BBQ in KC” debate.
Nathaniel Rider, M.D.

Undergraduate: The University of Texas at Dallas – Richardson, TX
Medical School:
Texas Tech University Health Sciences Center School of Medicine

Rider, NathanielI had a fairly unconventional approach to my current position. I’ve had a few careers already including drawing electrical schematics of airport conveyor systems, and at one point I was cofounder of a house flipping business. When the housing market crashed in 2008 I went looking for another career which turned out to be firefighting in Waxahachie, TX. It was my mandatory paramedic training that brought me to medicine. I did my undergrad work at the University of Texas at Dallas in Richardson, TX and followed that with medical school in El Paso. I’ve been married for fourteen years to the most patient woman I have ever met, and I currently have five kids with one more on the way. My family and I love hiking and history, which makes Missouri extremely attractive because it has a lot of both of those things within a couple hours’ drive.
Jeremy Serreyn, D.O.

Undergraduate: Minnesota State University, Mankato
Medical School: Kansas City University of Medicine and Biosciences

Serreyn, JeremyHello! I was born and raised in a Lakeville Minnesota, a suburb of Minneapolis. After 18 years there, I decided to spread my wings and move 50 minutes south for college while still living with all the same friends I had since childhood. After my time at Minnesota State, I made the move to the best (and far less cold) city in the Midwest, Kansas City, for medical school. It was one fateful night during my first year when I swiped right on my eventual wife who persuaded me to complete a rotation in emergency medicine, citing my lack of attention span and enjoyment for constant challenges. From that point on I was hooked. I chose UMKC for my residency training because of its longstanding reputation, as well as the opportunity to help some of the under-served population in Kansas City. My interests outside the ED include military medicine, running, hiking, beer & trying to convince my wife to let me adopt another dog.
Matthew Whitton, M.D.

Undergraduate: Texas A&M University
Medical School:
Texas Tech University Health Sciences Center-El Paso Paul L. Foster School of Medicine

Whitton, MatthewHowdy y’all! So I was born in Northern California but consider myself a Texan as I lived there for about 23 years. I wear boots and like to country dance, but unfortunately I don’t have a Texas accent (I blame that from being born in California). I graduated from Texas A&M University in 2013, worked as an ED scribe for a year and a half, then I was accepted into medical school at Texas Tech University Health Sciences Center in El Paso. To say I was ecstatic when I found out I matched here would be an understatement. What drew me to this program was that Truman is a giant safety net hospital where anything and everything can come through their doors. I’m happy to be living in Kansas City as it has a lot to offer its residents. For example, Kansas City BBQ is some of the best I’ve tasted and I believe I committed a Texas sin by saying that. I enjoy snowboarding and wakeboarding, shooting at the range, watching the Cowboys and the Stars, or grabbing a beer at one of many Kansas City bars.
Riley Williams, M.D.

Undergraduate: Kansas State University – Manhattan, KS
Medical School: University of Kansas School of Medicine

Williams, RileyI was born and raised in Topeka, KS, where I fell in love with medicine during high school sports by pestering our athletic trainer with questions. I was lucky enough to walk on to Bill Snyder’s football team at Kansas State with two of my best friends, where I enjoyed two seasons of premiere sideline views while earning a degree in Biology. After graduating, I loaded up my things, said goodbye to my friends and set off on my journey to the far away land of Kansas City (Kansas), where I would complete my medical degree at KU. I guess there was also a brief time when I lived in Lawrence, picking up an MBA and a fiancée along the way, but do not think that swayed my allegiance – Go Cats! While in medical school, I fell in love with the excitement of Emergency Medicine, and Alyssa and I both fell in love with Kansas City. I wanted to train at a county hospital and UMKC’s storied program attracted me. As soon as I saw the rapport between the staff and residents, I knew that Truman was the place for me. When I am not at the hospital I am probably somewhere playing fetch with my dogs, at the gym trying to lift something heavy, or am asleep on the couch with The Office playing in the background.
Hunter Winstead, M.D.

Undergraduate: Augustana College – Rock Island, IL
Medical School: University of Illinois College of Medicine – Rockford

Winstead, HunterI was born in a small town in Northern Illinois. For those not familiar with Illinois, I say I am from northern Illinois, but not Chicagoland. For those versed in Illinois geography, I grew up in the first cornfield south of Rockford (but really, my high school owned a cornfield to teach Ag class). I went to college at Augustana College in Rock Island, Illinois, one of the four Quad Cities on the Illinois/Iowa border. I met my wife at Augustana, and we got married between college graduation and before we both were on our way to the University of Illinois College of Medicine in RMED, their rural medicine program. We went through medical school married, which was fun and a little hectic. We couples matched to Kansas City and we are both thrilled to be here. We found the amazing city of Kansas City by accident during a conference here, and each time we came back for interviews we liked the culture, food, and atmosphere more and more. My wife beat me to the punch and fell in love with her Med-Peds program after she interviewed, before I even interviewed here. However, I was quickly behind her on the interview trail and in choosing Kansas City as where I would like to train. After my interview, I was drawn to Truman for a number of reasons. The primary reason was the history of the program and its strong representation through its alumni. Yet, with its long history, the program is constantly changing and working to be better, and has a good blend of county and academic medicine. Lastly, I felt that if I trained here, I could work anywhere given the strong training and diverse patient population. Outside of the ED, I spend my time playing board games and video games, cooking new recipes with my wife, binging Stranger Things and Great British Bake Off, going to the river market, travelling, and trying to limit my time on the computer by reading. My three favorite restaurants in KC are Blue Koi (amazing dumplings), Winstead’s (cheap burgers and the last name), and Messenger Coffee (where I can watch people bake as I work on things, similar to the British with less accents and no competition).
