Personal statement

The thing I want patients to understand about hip and knee arthritis is knowing when you need to seek treatment. Pain lasting for more than 4-6 weeks is probably not going to respond to ibuprofen. There's different treatments depending on your age and what's exactly going on. I want to get to know you and figure out what's the best treatment for you, whether that's doing medication or physical therapy or surgery. Seeing patients from start to finish is important, that way you can have continuity of care so that you know exactly what's going on during their entire treatment process.

My core reason for going into medicine is to offer personalized treatment. I'm not a "operate first, meet you second" kind of doctor.
