  • I could not have asked for better service, promptness and satisfaction with the treatment ordered. Thank you very much!
  • They were wonderful, I was seen right away.  I was treated with kindness and compassion from everyone from beginning to end, from check-in, X-ray, check-out.
  • The OAL staff is always friendly and polite. Your diagnosis and treatment are explained in great in detail, so you truly understand what is going on. They also go above and beyond with insurance to get things preapproved, I would never go to another place.
  • #1 in my book!  This team replaced my right knee, and are now in the prep stages to replace the left one. One stop shopping as far as diagnosis, actual surgery at Lancaster General, along with rehab. The surgery team is great, and the rehab team very easy to work with and very thorough.
  • My doctor and staff took the time to explain the cause and treatment I would receive. Very professional!
