Outstanding doctor. My husband and I have been seeing Dr. Hwang for over 12 years. She is always thoroughly prepared for each visit, has excellent listening and communication skills, and her follow up is amazing. She gets back to you to answer your questions or concerns or to refill or change medications almost immediately, sooner than we would ever expect, including on weekends and vacations via NextMD. (Worried she might get burned out because she is so conscientious.) Lab results are sent to you immediately. Plans of care are meaningful reminders for you to follow, not just fill in the blanks to satisfy regulatory bodies. My husband and I are elderly, with long problem lists. She stays on top of it all, including all the preventive vaccines, etc. Amazing. Best Internist we've ever had in our years of living in different locations.
