“All I can say is how life changing he is! I dealt with a dysregulated nervous, sleep issues, depression, severe anxiety, just stuck in fight or flight. I tried to ledt togus va help for 3 years and I decided to go outside the va. He was my first choice and I got a sgb done. An dr.Fredrick honestly relates and understood and after the injection I felt a change in 30 minutes then the 1 week I got ba k to working, gym slowly, 2 week I was back to normal about 90% and then week 3 and 4 im operating like i was myself. Im a couple months into it and ive honestly never felt better. He saved my life and I owe this man everything honestly. He is truly a doctor that listens and helps you. Highly recommend 👌 I owe him everything for bringing me back to what I was! The man is beyond great, life saving, I will always pray for thanks because of him and pray for only great things in his life! I cant say thank you enough!”

“Dr. Littlejohn is fabulous. I came down from Canada for a spinal epidural injection at L5/S1, because I had to wait too long up here to get an appointment. Before I even got there, Dr. Littlejohn kept me at ease with his responsiveness and comforting communication. I was quite nervous going into the appointment as this was my first epidural. He calmed me down, took his time with me, walked through my scans and the procedure, and took great care of me throughout. I would recommend him to anyone and am so grateful I came down to see him. My pain has improved significantly. Don't be discouraged if it doesn't happen in the first week or two, I started really feeling the improvement at week 3.”
John McIntyre
“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.”
Riley Anthony
“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.”
