“I sliced my Achilles tendon in half and saw Dr. Casteñeda for it. She was very helpful and kind. Another doctor might have put me through surgery for my injury, but Dr. Castaneda was able to get me back on my feet without it. The girls in the casting room were also friendly and fun and made my time in the office go by quickly. Thanks team, I'm happy to be walking again!”
