Guess I can say I am a lucky spinal cord injury survivor. It has been a hard year of rehabilitation after Dr. Koo fixed my neck after a freak accident. I owe everything to Dr. Koo, Markham Stouffville Hospital and Lyndhurst center staff for my entire recovery. From being nearly paralyzed and stuck in bed, Dr. Koo took me into the operating room immediately and into rehab after. I am now a year out and have made near full recovery. Words cannot express my gratitude.

Even though I was disappointed to hear that surgery was not in the cards for me, I was very glad to have met this doctor. He is the first person to fully explain my ailment and described alternative treatment I can pursue. Very caring person that took his time. I would recommend!

Dr. Koo performed a L2-L3-L4 spinal decompression and spinal fusion to address my stenosis condition that I had been trying to manage for over 20 years.

For the first time in as many years, I can get out of bed, shower, walk and perform all normal duties with little or no pain. In just six weeks after the procedure, I am able to walk 10-12 pain-free kilometers each day.

This morning I was given the green light to resume all activities with NO restrictions!

I cannot thank Dr. Koo and his team enough. Professional, punctual, knowledgeable and simple amazing at what they do! I highly recommend Dr. Koo for his insight, and ability to perform this surgery and thank him sincerely for giving me the ability to relieve me of the intense pain I had been living with for so many years.

Most grateful, JM.

Dr Koo gave me a life back I didn’t know I had left. I’ve had back and leg pain for 20 plus years so long I can’t remember. In the last 2 years the pain was much worse and I could only walk a few feet without my legs giving out. I sa Dr Koo who explained everything so well he is so calm and relaxed he made me more confident. Pauli his secretary was great and set everything up pre op and it all went smoothly .After surgery : a lumbar decompression L 2to L5 I woke up without pain for the first time in years. I just had my 3 week check up it brought tears to my eyes to see this wonderful Dr who changed my life so dramatically. I can’t recommend him enough. Also I’ve never been to MSH before and it was so clean and the staff were incredible so very kind and organized. Thank you so much Dr Koo

How can you really be punctual when you have so many patients waiting to see you. Dr. Koo made me feel so comfortable even while having a broken ankle. Great bedside manner. One of the best doctors I’ve experienced!
