This doctor not only has the hands of gold but is very caring and thoughtful. 5 minutes before my mom's surgery he ran into to tell us he found another issue that she needed addressed. Not a single doctor, and she saw 4 before, with more experience, mentioned the thoracic spine. My mom ended up having 2 surgeries with Dr. Lo while he was at Columbia. Before she couldn't walk for more than half a block, now she lost 40 lbs and walks 2.5 miles daily, 3 years later she is better.
