Dr. Mark Edward Allison, MD

He is the rudest angry sounding doctor I have ever met. Does not care about you symptoms, just barks orders to read the line, when tried to tell him there is a dark / gray area in center of vision hes said I don't care about that can you read the line.

Over time, he has become crass and rude. His care for patients is low. His fellow MDs call him the "used car salesman of opthamology."

Dr. Allison implanted Rezoom lens on my eyes because I was tired of not seeing the clock or the tv without my glasses. THAT WAS ALMOST 10 YEARS AGO (2010) AND MY EYES ARE STILL FANTASTIC. I can see a bird on the top of tree or read the back of medicine labels on the store shelves. I think he is fantastic and have never regretted it.

Back when RK was the "it" surgery he basically told me my eye was better than saw. He got mad because I wouldn't let him chop up my left eye. Just very ugly to me.. 20 years later my right eye is a nightmare. 20 20 Eyecare did the best they could to fix his mess.

Rude sums it up

I'm really trying not to be to critical but he does this to himself, he came Barrelling in does not introduce himself, is not wearing a badge of any type. Starts to inform me he knows what's wrong with me and I stopped him and said hello my name in Kathy's, he then realized he never introduced himself to me. He honestly looked like he just finished mowing his yard. I would have never taken him for a Doctor. A little professionalism would really help him. Very loud and overbearing, He never even looked in my eyes and he already had me diagnosed, I really don't think he cares what patient has to say. Comes across as a know it all doctor who does not have time for stupid questions.

Absolutely the worst - should not be allowed to practice.

Most horrid doctor I have ever encountered. No greeting, no eye to eye contact. Extremely condescending. Told me I will be '6 feet under' soon. So unprofessional. Embarrassed that Warren Clinic would allow someone like this in their network.

I'm very disappointed in the outcome of my cataract surgery. I spent the extra money to have the surgery that supposedly would keep me out of glasses. The surgery failed and now I'm in glasses again.

Dr. Allison may not be the friendliest doctor initially, but he has been amazing at figuring out what's going on with me and being extremely available when I needed him. I first went to him when I had a severe case of iritis. He immediately identified what was wrong, prescribed the right medicine, and followed up with repeatedly to make sure I was doing okay. He then gave me a method to reach him if this happened again as in my case, he said I could have lost my vision if I had waited much longer to get help. He might not tell you what you want to hear, but he definitely knows how to do his job and he can be very compassionate.
