Dr. Hsia left her career in banking and finance to pursue Optometry because she enjoys serving people on a more personal level.  She loves science and everything about the eye.  Beyond her expert clinical care, she has also received accolades for her optometric research.


Dr. Hsia enjoys being part of the Dove Canyon Optometry family because the front staff is awesome!  Their attention and care to each patient goes above and beyond.  She enjoys the teamwork and camaraderie at DCO.  Most of all, she loves our patients and how friendly everyone is.


In her spare time, Dr. Hsia loves spending time with her family.  She and her husband are busy raising their 3.5 year-old son and 15 month-old daughter.  Their dog, Milo, is by far their most well behaved child.  Dr. Hsia also enjoys volunteering her skills and time on medical missions trips (Baptist Medical and Dental Missions International) and hopes to bring her whole family on one soon.
