I became a patient of Dr. An's after seeing several other orthopedic doctors.  Was referred to him by a friend as I needed complicated spinal surgery that the others wouldn't attempt.  I was completely satisfied with the pre- and post-care that I received from Dr. An and his staff and especially the post-surgical outcome!  It's been more than 5 years with no significant issues.  Am so relieved to see that he is in the directory of being in-network for my new insurance!  I wouldn't hesitate to go to him again if I need spinal surgery.
