TESTIMONIALS

     My name is Kevin Flood and Dr. Chen in L.A. is one to be held up for others to see. MY arm has been broken 5 or 6 times in my life. The last time was the worst. 
     Dr. Chen actually fixed and reconstructed my arm and wrist after this other doctor screwed it all up. I was in seriously bad pain and I could not turn the palm of my hand in an upright position. 
     I was told by a doctor that I trust that Doctor Chen is the best orthopedic doctor. He is Right! Three years now and no pain and my arm and wrist work perfectly. I do a lot of hard labor work and I can still throw a fastball! Thank you, Dr. Chen and your cool staff!"
