Meet Us

I grew up in upstate New York, Australia, and Colorado, went to undergrad in Tennessee, medical school at Loma Linda University, graduated from Loma Linda Pediatric Residency in 2021, and now I am a Pediatric Chief Resident. I love to be outdoors, whether that be swimming in the ocean, camping in the mountains, scrambling on the rocks at Joshua Tree, hiking in the hills around Loma Linda, or spending time at the park with friends. I also enjoy baking (my pumpkin cinnamon rolls seem to be a resident favorite), doing various types of crafts, and borrowing people’s kids to play with. I am really enjoying chief year this year, continuing to build relationships with our amazing residents and faculty (the people are my favorite part of this program). After chief year I plan to work as a general pediatrician in the outpatient setting.

I am a Southern California native. I went to the University of California, Berkeley for undergrad and A.T. Still University, School of Osteopathic Medicine in Arizona for medical school. As part of the Primary Care Track, I had the unique opportunity to work at both Loma Linda University Children’s Hospital and Riverside University Health System during residency. I was a Primary Care Track Chief Resident during my PGY-3 year and I am excited to be a full-time Chief Resident for the Pediatrics Department this year. I enjoy traveling, going to the beach, and trying new foods. I plan to work as an outpatient general pediatrician.

I’m an outgoing and social person that enjoys pretty much any activity. I love outdoor activities like sports, camping, barbecuing, swimming, hiking, and more recently my wife and I have enjoyed taking our newly adopted dog on these outings. I also enjoy relaxing and hanging out playing board/card games, watching movies, or playing video games. My wife and I love having groups of friends over to hang out and play games! One of the main things I’m excited about this year as a chief resident is to get to know all the new and continuing residents better, and to be a “safe” or “go to” person for the residents when they have questions or concerns, or simply when they’re looking for someone to chat with during time off. I also now have a beautiful daughter named Eden who was born July 30, 2021, so that’s pretty amazing! 

I am originally from Miami, Florida but I have loved my time in Southern California. Before starting medical school here in the “IE” at Loma Linda, I went to an HBCU in Northeast Alabama. During my free time I love to listen to podcasts, watch and play basketball, play music, and hang out with my friends, family, my wife and my new daughter. After chief year, I’m interested in a future career in medical education. I am passionate about supporting our next generation of physicians!

I grew up in Northern California Bay Area, went to UC Davis for undergrad, and then went all the way to St. Louis University in Missouri for medical school. One of the best things about Pediatric Residency at Loma Linda was all of my co-residents and our awesome faculty--I’m so excited to continue working with them all this year and our new interns. After chief year, I’m hoping to start fellowship in Pediatric Emergency Medicine. When I’m not at work I can be found climbing, cooking and baking (but let’s be honest, the best part is the eating), painting/drawing, or crafting. I also enjoy spending time outside (when it’s not >100 degrees) and am always ready to try new outdoor activities! My superpower is noticing any and all dogs within a 40 ft radius of wherever I currently am, and a fun fact about me is that my Bacon number is 2

She works as a pediatric hospitalist at Loma Linda University Children's Hospital and Riverside University Health Systems, while her husband alternates between Loma Linda internal medicine inpatient and Moreno Valley Med-Peds outpatient clinic.

Dr. Loh was born and raised in Honolulu, Hawaii.  She attended Loma Linda University for both medical school and residency.  You can often overhear her say, “I have the best job ever! I get to have a blast interacting with babies, kiddos, and teens in my University private practice, and then have the privilege to work with residents in the Newborn Nursery and in their Continuity clinic.”  She feels truly blessed to be a part of the Loma Linda Pediatric Residency family. Her special passion is her work with the Professional Development Coaching program for residents. Outside of work, Dr. Loh hangs out with her husband and three sons playing sports, going to the beach, eating out, and traveling. 

Dr. Vercio moved from the Pacific Northwest to attend LLUSOM, and stayed for residency in Internal Medicine and Pediatrics. Since completing residency, he has practiced at LLU at various locations including Beaumont clinic, Moreno Valley Med-Peds, Redlands, and was the medical director of the Pediatric Residency clinic as it transitioned from being a Children's Hospital-based clinic to SAC. Because he and his wife are committed to global service, they spent a year and a half in India in the small town of Ottapalam which gave him a new appreciation for practicing in a relatively rich resource setting.  He is interested in spiritual care, global health, clinical reasoning, teaching medical students and residents, and enjoys music, mountain biking, surfing, camping and hiking.

Dr. Tan grew up in Ontario, Canada but came to Loma Linda University for medical school.  She fell in love with Southern California and completed her pediatric residency at LLU. She spent her first post-graduate year doing locum tenens work in every corner of the country, but returned to Loma Linda to join the Pediatric Faculty Group.  In 2009, she began spending the majority of her clinical time at the SAC clinic and had the opportunity to be part of the tremendous growth of this organization leading to an intimate involvement with our LLU Pediatric program. The growth and education of the LLU Pediatric residents is now one of her passions. Joy outside of work includes snow-skiing, houseboating and traveling with my family.
