Dr Ko is an excellent pain management provider. He makes me feel comfortable to be able to tell him everything that is going on with me. When I was in my worst pain ever and was new to Dr Ko's care, I had a complete meltdown with my very first visit with him. He never made me embarrassed of how emotional I was from dealing with so much pain. Dr Ko has a special place in my heart for bringing my life back into my own control and I am able to do physical tasks now . Thank you to Dr Ko and the entire team!

Providence Patient
Excellent provider and staff!
Providence Patient
I am so very thankful & grateful that Dr. Ko had the foresight & knowledge to deal with the thoracic region of the spine back in 2012. Back then, most doctors dealt with cervical & lumbar. Without Dr. Ko's ability to perform those thoracic spine epidurals every 2 mos (back then that was the time limit which was extremely difficult to wait for, then the government pushed it to 2.5 mos & now to 3 mos which caused an increase in pain meds.that benefits big pharmaceutical comp NOT THE PATIENTS WHAT HAPPENED TO DO NO HARM???) Without Dr. Ko, I would not have been able to walk! He is my hero! For a few yrs I was able to continue working & led a normal life! Then the restrictions came, the longer I had to wait, meant the more pain my body endured. Until it couldn't anymore! My body started to break down, my neuropathy went to severe/all my limbs, could barely move, stopped absorbing nutrients and at end of 2015 I could no longer work/ no quality of life due to pain! Since then, I rarely leave my house unless to have an epidural, my treatments ex 1000 mg of IV Solumedrol every 4 wks are done at home for the severe neuropathy caused by debilitating back pain. During all of this Dr. Ko has gone above & beyond with his patient care, he takes time to listen, check in & is irreplaceable! I won't let anyone touch my back but him!
Providence Patient
