Dr. Allison Hennigan, MD

Extremely knowledgeable with great interpersonal skills.

Dr. Hennigan has been extremely helpful in helping me. After a quarter of a century of suffering with migraines, I have my life back again.

Dr. Hennigan is personable, extremely thorough in her evaluation, and sincerely wants to help. She has helped me and made adjustments as we've gone along. I am doing better and would recommend her highly.

Dr. Hennigan was the first neurologist to properly diagnose my wife with Lewy Body Dementia. We visited several neurologist including UT Southwestern before referral to Dr. Hannigan. Dr. Hannigan is very compassionate with both patient and spouse. She explained what to expect and to avoid. She is excellent and highly recommended. Best neurologist in the area for dementia related diseases.

I love, love this doctor. My experience with her on my first visit was fantastic. I love the fact that she stated that she would get to that when I asked her questions. She did not rush me, she took her time with me and explained the course of her actions. I was kinda feeling like my first time visit would be a no brained and a wasted trip, boy was I fooled. I finally found a great neurologist. Thank you Dr Hennigan for working with me and together we will get this all worked out.

I am BLESSED to have found her! She is patient, thorough and listens to her patients. I like the fact she has an extensive knowledge of Multiple Sclerosis and treats my MS without a ton of pills. I recommend her to everyone who needs a Neuro from Longview TX because she is worth the 45 minute drive to Tyler!

I was seen by Dr. Hennigan by referral on 5.24. I give her the highest ratings across the board!

My primary care physician referred me to Dr. Hennigan six weeks ago. After not hearing anything from her office, I called on 04/12/2017 and spoke to Ruby. Each time I call, Ruby always says that she received information the previous day, and was JUST going to call me.. She stated that Dr. Hennigan reviewed my file, and would not be able to do anything any different. Why did it take 6 weeks to find this out? Do not go to this doctor.

I am currently in the hospital at ETMC. Her bed side manner was impeccable. I was admitted with a heat stroke I threw up for about 7 hours and experienced major head ache that is an extension of head ache issues since my brain annuerysm three years ago. She understood my pain and the experience of electric shock head aches combined with weakness on my left side. This morning I am feeling much better as a result of her treatment and medicine recommendations. Thank you Dr. I am very grateful. Todd
