Chief Residents

M. Kalambata, MD

Hello, my name is Mwape! I was born in Zambia, but spent the majority of my childhood in Minnesota. I left the frigid winters to attend undergrad at Southwestern Adventist University in Keene, Texas where I studied Biology. I’ve thoroughly enjoyed the last 7 years living in Loma Linda, attending medical school and residency, and now I have the wonderful opportunity to tackle chiefdom with three amazing ladies and physicians. Outside of work, I’m all about finding the perfect balance between weight lifting, binge-watching TV, cooking, and hunting down the best new restaurants—I’m a total foodie at heart. I’m also a big fan of hosting game nights with my husband, while squeezing in some travel adventures whenever I can. Career-wise, I’m hoping to find a hybrid position to pursue both inpatient and outpatient pediatric medicine. If you’re like me and like a bit of everything (or just undecided), I am happy to connect with you this interview season. Best of luck!

Hi everyone! I’m Michelle and I feel honored to be working with such an amazing group of doctors! I am originally from Kentucky but I’ve slowly moved west, living in Maryland, Michigan, and now here and now I proudly consider myself a Californian. In my free time, I love traveling to obscure places, surfing, hiking, working out, listening to music from around the world, playing violin, and being spoiled by the amazing food my family makes whenever I visit them (Indian + Filipino). If I have a weekend off, I sometimes like taking off to Mexico to volunteer at the border for refugee health and I will be moving to Mozambique to work as a pediatrician at one of Loma Linda’s global health sites. I look forward to meeting you soon!

Hello everyone, I am so excited to meet all of you and to be working with my wonderful squad of Co-chiefs this year! I am a SoCal girl through and through. I went to college in LA at Occidental College and completed medical school at Western University of Health Sciences where I did additional training and teaching as an Osteopathic Manipulative Medicine Fellow. I was so happy I matched into the Loma Linda Peds Categorical program, as I could feel the culture of care and commitment to education when I did a peds MS-3 rotation at RUHS and worked with LLU residents and attendings. Outside of the hospital, you can catch me eating brunch at a new spot, spending time with friends in the sunshine, working out at a pilates studio, watching k-dramas, or browsing Barnes and Noble (even though I am on a book budget). Wishing you the best during the interview season and hope to see you soon!

J. Yoshisato, MD

Hi hi! I've been asked to introduce myself. I'm Jenna Yoshisato. I'm from Vallejo, CA in the Bay Area. I studied Psychology with an emphasis in Biology and a minor in Human Development at UC Davis for undergrad. The plant pathology lab I worked in graciously hired me after graduation and I got to live my cozy little plant path lab life for 2 glorious gap years while applying to med school. While I am personally from California, my family has roots in Hilo, HI, so we spent a lot of time in the islands growing up. Never dreamed I'd end up living there full time, attending med school at John A. Burns School of Medicine on Oahu. I may have also accidentally acquired a cat while there. Whoops. Now I'm here, loving the home I've found in LLU Peds Residency. I'm stoked that I get to extend my time here by serving as one of this year's chiefs alongside my incredible co-chiefs before I try to go off and live my hospitalist dreams. In my off time, you can find me hermitting with audiobooks and crocheting, while imagining what it might be like to leave the comfort of my home and experience more adventures for realsies.
