Jonathan Chandler portraitJonathan Chandler, D.O.

I was born outside of Tulsa, Oklahoma, but grew up in Lee's Summit, a suburb on the Missouri side of the KC Metro. I completed my undergraduate degree at Oklahoma State University (Go Pokes!), then moved back to Kansas City for medical school at Kansas City University of Medicine and Biosciences (KCU) where I also completed a Masters in Ethics. Throughout medical school, I had the opportunity to rotate at KU and was extremely impressed with the residents at KU. I felt KU offered a rich clinical learning experience, in an extremely supportive environment, with a variety of opportunities for residents to personalize their training to prepare for their desired career. Throughout my time at KU, my experiences have exceeded my expectation! I am excited to serve as a chief resident to give back to the program that has offered me so much. After chief year, I plan to pursue a fellowship in Pulmonary and Critical Care with the hopes of working in an academic setting after training.

I was born and raised in Kansas City and haven't gone too far from here yet. I went to the University of Kansas for my undergraduate degree. I am a third-generation Jayhawk so crimson and blue is in my blood. I studied Chemical Engineering but found my love for medicine while spending a summer during college working in a hospital. After graduation, I worked in a cardiology office while applying to medical school. I was thrilled to be accepted to KU for medical school as well and follow in my grandpa's footsteps who graduated from KU Med back in 1954. Medical school was an amazing four years that flew by, and when it came to deciding where to go for an Internal Medicine residency, I looked around at all the programs in the Midwest. After careful consideration, KU was again where I wanted to be and have been so grateful to call this place my home for all this time. I am married to my amazing wife Julia and we have two young kids Jack and Caroline who are wonderfully crazy and a black lab named Gus. I enjoy spending my free time with them and all of our family that we have in town. I chose to stay on as a Chief Resident to cultivate my skills as an educator, leader, and mentor. I plan to stay committed to the lifelong pursuit of medical education at every level and knew that becoming a chief would help me to achieve this. After chief year, I hope to continue my training to one day become a Cardiologist.

I was born in Kansas City and spent a few years in Minnesota before my family came back to Overland Park, a suburb on the Kansas side of state line. I went to college at KU in Lawrence, KS (Rock Chalk!) where I enjoyed eating Wang-burgers from the Wagon Wheel Café. During college, I was able to do research at the Kidney Institute at KUMC studying cell biology and renal pathology. I stayed at KU for medical school and loved the experience so much I stayed for residency. Our program does an amazing job fostering a culture of growth through mentorship and education. After chief year I am planning to pursue a fellowship in nephrology. Outside of medicine you can find me watching sports (Go Chiefs, Royals, Sporting KC and Jayhawks!) trying out a new happy hour in town, or spending time at the lake with family!

I grew up in Topeka, KS prior to spending my undergraduate years in Manhattan, KS attending Kansas State University. At K-State I completed my undergrad degree in Biology with a minor in Leadership Studies. Though my love for the Wildcats run deep, I was ecstatic to be accepted to KU School of Medicine and was fortunate enough to continue residency training here as well. Our leadership team, residents, and faculty are one of kind and a big part of why I wanted to pursue a chief resident year. I enjoy the enthusiasm to learn our residents and medical students bring to our academic teams each day. I am pursuing hospital medicine after this year with a goal of working in academic medicine in the future. Outside of medicine I enjoy attending K-State and Kansas City sporting events, spending time with family in Colorado (usually hiking), and exploring all the coffee shops and breweries Kansas City has to offer!

I was born and raised in a small town in the Chicago southland before moving to Kansas City to complete a combined BA/MD program at UMKC. While I had fully planned on returning to the Chicago area, the internal medicine program at KU caught my eye. During my interview day I witnessed a cohesive resident group that interacted like a big family. The culture at KU stood out to me amongst the other programs which I had interviewed. Three years later, I can without hesitation say that completing my internal medicine residency at KU was the right call. Our program has a collaborative compassionate culture that begins with our program leadership and is emanated by both our residents and interns alike. I can recall countless times where my resident colleagues would bend over backward for anyone in need. It was this culture that I caught of glimpse of during my interview day that convinced me to pursue my residency here and supporting this very culture is the driving ethos of our Chief Residents. The KU internal medicine program has helped me build a strong foundation in medicine which will serve me long into the future as I pursue a fellowship in Cardiology.
