I can be a hard critic of health care places and the people employed by them. Combine that attitude with an innate crankiness when I’m not feeling at all well and having to wait a while to see Dr. Liker, the result can be much less than pleasant. I was very pleased with my neck and back surgery. Dr. Liker was a world of difference from previous experiences elsewhere. It was good to be treated with attentive care. I felt safe and at easy from beginning to end--he was worth the long wait!

After many bad experiences with other drs i was referred to dr liker. I was at my witts end. Dr liker was friendly,opn minded and found the problem where others ignored it. 11 years later I am not pain free but the surgery saved my life as far as I'm concerned. Thanks Dr liker

This Dr has no regard for anyone's time. His staff in Santa Clarita are beyond rude. After four reminder phone calls I arrived to my appointment thirty min early with all paperwork completed,for a 9:30 appointment. Sat in the waiting are for 45 min before shoved into an exam room. Sat there for another hour. After sitting there I asked the person right outside how much longer, She got up walked,over to the door, said you're next them slammed it on me. Two hours waiting I left never to retu

Dr Liker is the solution to your pain and suffering. I recently relocated to the state of Nevada where I suffered from a serious L3/4 disc protrusion that left me seriously disabled. Local Neurosurgeons in Nevada where recommending Multi level fusion with barbaric metal implants and screws. I called my previous primary care doctor in Mission Hills Ca, and he recommended Dr. Liker. Minimal invasive procedure followed. Corrected Disc Protrusion at levels L3/4. Corrected Stenosis, Life is good!
