I reached out to him in desperation for my father who has 2 herniated discs and couldn't get an appointment at OA or the pain clinic for many weeks out. After multiple ER visits for pain he had succumbed to the fact that he was stuck living like this until next month. Dr. Littlejohn was responsive to my email even never having been a patient or having a referral and fit him in the next morning outside of normal hours. I can't thank him enough for the quick and compassionate care. He truly cares about helping people be pain free.

I have had back pain since I was in my late teens, 13 years ago I had surgery and was much better but the las few years it has been getting worse. Last summer I was in so much pain it was hard to sleep or function. I was referred to Dr Littlejohn and over the next couple of months he has given my life back, very grateful.
