December 07, 2016

I feel that the side effects were not talked about enough because I got very sick the day after and had to research into Botox to find out that it wasn't worrisome.

December 05, 2016

Dr. Brennan is friendly and professional. He is easy to talk to and showed concern for my condition.

October 25, 2016

I find Dr. Brennan to be so professional, and knowledgeable. he discusses everything with me, and helps me understand my condition and everything connected with it. It is very clear that he cares about me, involves me in decisions and helps me become well informed.

September 20, 2016

Dr Brennan is simply the best there is

September 18, 2016

Excellent care as well as kind compassion for my emotional state that day.

August 23, 2016

dr Brennen included me in the decision making process having been through this procedure once before and aware of my own needs

August 02, 2016

was seen on Friday and was told my provider was going to call in a script, the script was never called in and it was the weekend so was not able to get the medication I needed

July 22, 2016

Dr. Brennan is excellent in every area. I would recommend him highly to everyone!

July 05, 2016

Dr Brennan is just the best, probably favorite dr ever

July 04, 2016

Appreciate his concern and time he gives me to talk and answer my questions

June 23, 2016

my only concern is back up for this provider when he is out or unavailable

April 30, 2016

Dr. Brenin is an amazing soul. He does a great job at what he does in try to help heal people. He always treats you as a total person even when he is just addressing the issues of injections. You should give him a raise.

April 18, 2016

I don't believe I would be able to find better care anywhere. I would recommend this office to everyone.

March 15, 2016

Dr. Brennan is the very BEST!

March 07, 2016

They were concerned about how I was felling.

February 24, 2016

very good experience yes I highly rcommend this procedure and Dr. Brennan and associates to my friends suffering with needless migraines.

January 27, 2016

Provider seemed rushed, as I was the last patient of the day

January 26, 2016

Even though Dr. Brennan was running late, he made sure I had all my questions answered, was concerned about my current migraine challenges, and listened to my coping strategies and resources that I have in Logan. He cares about my overall health and that is immeasurable to me.

January 12, 2016

I couldn't be any happier with Dr. Brennan. He is so respectful, helpful, and professional. I feel like he asks questions until he understands my situation perfectly. He makes suggestions and gives ideas that feel like they will be very helpful for me regarding the chronic migraines I've had for over 24 years. I feel like finally we are making significant progress. I am so very grateful! I've had only a few minor headaches since June, and it's January!

November 24, 2015

Dr Brennan is a very concerned and caring professional. Though is is busy, he takes the time to answer questions.

November 05, 2015

Always a wonderful experience with you facility, the receptionist/secretary Debbie Bettinson is the absolute sweetest/professional/best/goes out of her way to help, awesome nursing staff, and Doctor Brennen is the greatest. When someone (my daughter) is so sick and in so much pain for such a lengthy time of her life, it means so, so much to have such a positive experience time after time.

September 30, 2015

Dr. Brennen is AWESOME & GREAT, professional, knowledgeable, considerate, and cares. I just wished he had more appointments available.

September 29, 2015

This was my second visit with Dr. Brennan.

September 09, 2015

Dr. Brennen is the best!

August 07, 2015

I was very nervous about the trigger point injections but Dr. Brennan took the time to explain it to me. I thoroughly enjoyed the fact that once he realized I might not be the 'average' patient, he took the time for a discussion with me on the science behind the injections - including past and possible future studies.

July 21, 2015

Dr. Brennan is excellent.

July 02, 2015

usually I still have a migraine for at least a couple of weeks. this time I walked out the door without one. We are making progress!!!

June 15, 2015

Just love Dr. Brennan!

April 24, 2015

my experience with this doctor was markedly different than before. He was very kind, very willing to answer my questions, treated me respectfully, and gave me prompt treatment without delay or even putting me through another series of activities to determine whether I was being honest about my condition. I really appreciated being respected and being given information at my level of understanding.

April 22, 2015

Dr. Brennan did an excellent job of explaining what he was doing. Excellent 'bed side' manner. One of the best doctors I have ever experienced.

April 14, 2015

dr Brennan is the absolute best. Him & Susan Baggaley are the best drs you have up there, would recommend them to anyone!!!

February 24, 2015

Outstanding care. Can't say enough good things about this physician

November 19, 2014

Excellent and caring doctor! I appreciate how concerned Dr. Brennan is with the botox treatments. He tries to make sure that each injection is placed where I can get the most pain relief from this treatment! ;)

September 08, 2014

dr Brennan was awesome. he talks to you in words that u can understand and makes sure that you do before proceeding. he is constantly asking if u r ok during the procedure. u have complete confidence in Dr. Brennan.

August 17, 2014

Dr. Brennan is a very kind, courteous and likeable person. He addressed my concerns and wanted to make sure that I was happy with the botox procedure and wanted to know of any areas in my head/neck/back that would benefit from the treatments that I needed for my migraines.

August 04, 2014

Dr Brennan is outstanding. He is so easy to communicate with and truly listens to what I have to say. I wish more doctors were like him.

July 05, 2014

Have all ready recommended DR BRENNAN

dr Brennan was awesome. he explained the procedure as he went. I was extremely happy with dr. Brennan.

April 28, 2014

Dr Brennan is down to earth, easy to talk to. I rate him very highly.

April 28, 2014

I think Dr. Brennan is the best! He is awesome!

April 14, 2014

Dr. Brennan seemed a bit rushed that day. I travel 5 hours each way and spend the night in a hotel each time I see Dr. Brennan since he is a specialist that I trust. It's important to me to have time to ask questions and discuss the treatment.

March 06, 2014

All Good

February 05, 2014

As an established patient of Dr. Digre's this wasn't my first visit to the clinic; however, it was my first visit with Dr. Brennan for Botox and he was very informative and answered all my questions very thoroughly.

January 27, 2014

had concerns about medication and felt like it wasn't addressed effectively

December 31, 2013

Dr. Brennan spent extra time with me to carefully go over my medications and PT to make sure that I'm doing all I can to improve my health. I really appreciate his attention and concern.

December 28, 2013

Dr. Brennan was incredibly caring and helpful. He always cares a great deal about my Botox injections and their efficacy, but he also made great efforts to help relieve my immediate pain.

December 21, 2013

extremely positive experience

October 21, 2013

Please introduce the role of the resident/fellow who comes into the room with scheduled physician. It was not clear to me that the physician that I was scheduled for is not the one who would perform the procedure.

October 14, 2013

he always takes great care to make sure that he places the injections the the best places

October 07, 2013

I thought the doctor was very good, very personable and knowledgeable. I felt very comfortable during my appointment.

September 09, 2013

Dr. Brennan was very nice and took the time to explain medications and other treatment options for my headaches. I was impressed with how long he spent with me and never seemed rushed. He took the time to answer any questions and throughly explained my treatment plan, and the other services the clinic provides. Thanks!

August 22, 2013


August 14, 2013

Dr Brennan was amazing and spent extra time with me explaining lots of different things. I appreciated it.

August 14, 2013

Dr. Brennan is knowledgeable, caring and genuine.

August 12, 2013

dr Brennan went above&beyond spending extra time explaining procedures and other related things.

July 16, 2013

Dr. Brennan and the staff are always excellent.

June 25, 2013

Dr. Brennan was very short with me when I was trying to give him my medical history. He kept saying he had to go and seemed very impatient. It took almost two years for me to finally get an appt. and I think he should have acted more patient with me. He seemed knowledgeable however.

March 11, 2013

First time meeting and having patient care with Dr. Brennan. Found him to be very likeable, professional, and informative. Was very at ease with his care during my procedure.

December 03, 2012

His confidence in his diagnosis was comforting but really threw us off balance because we did not think it would be so easy without an MRI.

November 27, 2012

He let me know exactly what he was doing and why. I felt very comfortable with the injections I was getting because he knew so much about them and informed me about as much as he knew. I would have to say it was the best doctors visit I have had.

October 04, 2012

Very caring about my situation. Nice to have this experience with a doctor.

October 04, 2012

Dr. Brennan has been an excellent provider throughout our experiences with him. He has provided the only lasting relief she has received after years of trying many treatments. We understand that her headaches are very complicated and impossible to cure, but Dr. Brennan has our complete confidence and has met with a good measure of success.

July 09, 2012

We are just grateful that you have accepted our case and hope you can resolve the problem so wecan get back to work and live a normal/productive life again.

May 18, 2012

EVerything was excellent. We appreciate being given the opportunity to participate in this experimental treatment.

February 14, 2012

Dr. Brennan was wonderful

February 03, 2012

Dr. Brennan was very clear and concise with what needs to happen and I appreciate him explains things so well on a level that I could understand.

Academic Bio

Dr. K.C. Brennan is Assistant Professor of Neurology at the University of Utah School of Medicine. He was educated at Georgetown University and the Columbia College of Physicians and Surgeons.

Dr. Brennan's clinical practice is dedicated to the headache disorders. These conditions, which include migraine, cluster headache, and post-traumatic headache, are disabling, often stigmatized, and poorly understood. It is becoming increasingly clear that these disorders are not 'just headache,' but complex disruptions of brain excitability and homeostasis.

Dr. Brennan spends much of his time examining the basic mechanisms of migraine and post-traumatic headache. His lab uses a variety of techniques, in animal models and in patients, to understand the neural circuit disruptions that cause an otherwise normal nervous system to produce pain.
