What People Say About Dr. Mark Liker, MD

Showed up to my appointment about 10 mins early. I had been waiting 5 weeks for this appointment in pretty bad pain. I was excited for this and the hopes of moving forward in life without the pain I have been living in. I waited in the waiting room for 90 mins before being taken to a room and there was told it would be another 30-45 mins before the doctor would be with us....I left. My time is important to me and I am sure Dr. Liker's time is important too. I wish he would take that into account when booking appointments. I'm not going to trust a doctor that can't manage his own business to cut on me EVER!!!

My experience was phenomenal. I was in his office for over 2 hours but that was the least of my worries and it was all worth it. He and Dr Patel listened and evaluated me in the most competent way i have experienced. I had seen 2 other incompetent doctors prior to Liker and Patel. They were professional, patient, accurate, and listened. Reviews matter.

Dr. Liker and his staff have treated me professionally, kind, considerate, and most important, my back surgery has been a success! This was my third surgery (first two not by Dr. Liker), and the third time was the charm. With my unusual history, I had some reservations, however my confidence in Dr. Liker and his skilled approach, and supportive staff, I am beyond grateful for the outcome, and anticipate only feeling better and better. He comes highly recommended by me.

Dr. Liker has been my spinal neurosurgeon since 2013, with two fusions and a hemilaminectomy during that time. He is an amazing surgeon and I wish I could leave a 5-star review, but cannot. He has a bad habit of condescending to his patients and even telling untruths if it serves his purposes. A recent MRI on my cervical spine clearly shows a herniation at the C7/T1, causing myelopathy in my left arm due to nerve impingement. He is sending me for nerve testing of the ulnar, and was evasive.

My name is Tina Fey. My husband Tim saw Dr. Liker, on Dec 11. Dr Liker and his staff are great people. They care about other people and helping them. In all my years seeing my husband going to other Drs. No other Dr have compassion. Dr Liker does. Thank you Dr Liker and your staff for restoring our faith in Dr's like you!

I went for a consult with Dr. Liker, we decided to start the process to get a neck surgery. Days after i saw him, i started having more pain and i called his office and after 48 hours later, no one called me back. I called back several days later asking what happened and the attitude that I received was rude and unprofessional. I don't know what kind of doctor he is but the service I received was more than enough for me to search another doctor.

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!
