About
Dr. Sun has delivered general internal medicine from his office in the XiMed Building on the Scripps La Jolla campus since 2002. He holds board certification from the American Board of Internal Medicine and trained at UC Davis Medical Center, where he completed a Chief Residency year teaching other residents. Dr. Sun approaches each patient as a partner in their own care. He coordinates between specialists, explains evidence from medical literature, and helps patients shape their own treatment plans. The practice runs on a hybrid model: a traditional track serves most patients, while a Concierge Option through Concierge Choice Physicians gives a limited number of patients expanded access to Dr. Sun. Every physical exam runs 45 minutes and covers all active medical issues. The office also offers same-day appointments, telemedicine visits, and walk-in vaccine hours on Wednesdays and Fridays.

Concierge Option members receive reserved appointment slots at the start of each morning and afternoon session. They also get a dedicated phone number that connects to the office manager during the day and directly to Dr. Sun on nights and weekends, direct email access to Dr. Sun, a portable USB drive containing their medical information, and access to a network of concierge physicians when traveling.
