I love Dr. Dassel! I will definitely return to him when I am pregnant again.

January 25, 2017

Dr. Dassel is always amazing. He takes the time to explain everything and never makes you feel like he is in a rush. He answers any questions I have very thoroughly.

January 23, 2017

Dr. Dassle is the best OB I have had. The only reason I am willing to stay with the University is because of him. However, if the parking situation does not improve by my next visit, I will begin looking for a new OB at a different hospital.

January 08, 2017

Dr. Dassel always considers all factors when assessing my medical problems. More than any other care provider I have had, Dr. Dassel takes the time to look at the big picture, and make connections that a lot of other doctors miss. I trust him to make educated decisions, and research any conditions he is not familiar with.

January 08, 2017

I am always very impressed with the concern and time Dr Dassel takes to listen and discuss next steps for my condition. I feel this is one of the reasons my condition seems to be improving --- knowing I have a doctor who is as interested in helping me feel as healthy as possible.

December 09, 2016

Visiting a gynecologist has always been a really stressful and scary ordeal that I'm not sure many women are fond of. Dr. Dassel though, is thoughtful, informative, patient and has an incredible bedside manner. He took time to explain reasoning and concerns and even drew a picture so I could better understand what he was talking about. I was late to my apt. and was concerned that I was taking too much of his time, but he made it clear that my care was important. I wish more Doctor experiences were this way!

November 07, 2016

September 22, 2016

Dr. Mark Dassel showed genuine concern for my issues, and spent a lot of time with me to try to figure out what was going on and discuss the issue with me. He gave me multiple treatment options, which I appreciated. I had seen several doctors before seeing him, and he demonstrated the most knowledge and was able to give me options for additional diagnoses and treatment that had not been presented in the past. He is the best doctor I have seen so far for women's health issues.

September 21, 2016

Dr. Dassel is one of the very few & great doctors I have had in awhile.

September 20, 2016

The best doctor I've had he had really taken charge in trying to figure out my current health issues as well as treating my existing issues. He had a wonderful sense of humor and great caring nature. But most important of all is his honesty be didn't lie to me about my treatment. He doesn't say it can be this or that, he tells me honestly if he doesn't know.But he is willing to find out and help me find a solution to my health issues.

September 13, 2016

September 11, 2016

I was blown away with the personable care I received. The knowledge the doctor had was impressive.

I was listened to. I'm so impressed with this doctor.

August 09, 2016

March 14, 2016

tough treatment (trigger point injections), but very impressed with the genuine care and enthusiasm shown by dr. Dassel. he takes the time it takes to listen and discuss, can't recommend him highly enough.

March 09, 2016

I did ask a few questions that weren't answered. I was hoping to get more information...But he was still very informative about other things and we only had so much time to discuss. I will follow up at my next appointment.

February 15, 2016

Very, VERY impressed and grateful to see Dr. Dassel who knew so much about what I was seeing him for. I'd been searching for a good provider for years so I am so thankful to have met with Dr. Dassel.

January 06, 2016

I've already highly recommended him to my friends. I also told him I trust him with my life, and I mean that. He performed surgery on me with the utmost care and did an excellent job.

December 24, 2015

I had two concerns when I made the appointment. I brought up both concerns and only one was addressed. I brought up the second concern again and it still was not addressed.

December 14, 2015

Dr. Dassel was great! He was able to give me answers about questions I have had for years. I am so grateful he knew some answers!

December 03, 2015

I have always liked Dr. Dassel and I used to refer him to anyone but for what I am being treated for now I don't think that he is listening to me and jumps to conclusions. I feel like he has something in mind and doesn't want to move on from that. I still think he is a great doctor I just think he could be better at listening.

November 02, 2015

Dr. Dassel, the best, friendliest doctor I have ever found. He showed much concern and care for my illness. He has empathy beyond imaginable for me as his patient. He spent a long time with me in the exam room learning about me as a patient he had never seen before. Getting to know me and how my illness affects me. He then gave me options to help fix my illness. Options which no other doctor has given me before. I thought I was going to have to have surgery because that was what others doctors were saying. But he gave me other options! He has great compassion for others and really wants what is best for his patients. Dr. Dassel is very knowledgeable in his practice.

October 24, 2015

I recommend him to my sister and now she's a patient

October 24, 2015

October 07, 2015

I feel comfortable with, and confident in Dr. Dassel.

September 21, 2015

Dr. Dassel makes me feel like a patient instead of a customer. I can't explain how much that means to me.

September 13, 2015

September 07, 2015

Dr. Dassel is the best Gyn doctor I have been to many and they don't compare.

August 22, 2015

Dr. Dassel is an excellent physician.

August 20, 2015

Dr Dassel is a great doctor! He is easy to talk to, friendly, and very competent. I am glad he is taking care of my follow up visits, but when I sent a message after my visit through the mychart system, a medical assistant answered it and I would have preferred that it be Dr Dassel who was dealing with my correspondence. That made me a touch uncomfortable.

August 20, 2015

He is amazing. I really appreciated him listening to me and striving to figure out what was best for my health, especially in such a short amount of time.

August 15, 2015

Dr. Dassell is an amazing doctor. I have reccomended him. Every woman should experience care like his.

July 15, 2015

July 09, 2015

Dr. Dassel is very good and I would recommend him to everyone.

July 06, 2015

After nine visits to other medical staff to in my efforts to resolve my issue, I felt very confident in Dr. Dasell due to his thorough examination review of my case. Not only was he informative he communicated in a very approachable way, leading to a discussion rather than simply giving me his conclusions. I found refreshing to understand his thought process. A few minutes with him is like twenty minutes with any other doctor.

June 16, 2015

therapy recommend but the details of the therapy were not explained to me. I do not know what to expect. my anxiety was addressed and he increased medication that doesn't work.

June 13, 2015

Dr. Dassel is fantastic, I don't think I could ask for a better provider!

June 10, 2015

He drew pictures for me to help me understand my body better, haha. It was actually very helpful, and put him on the same level as me. It allowed me to better explain it to my husband later.

May 19, 2015

I can never get in touch with him. he will not return emails or call me about my concerns.

May 15, 2015

was glad that he set up tests to try to find out what the problem is. he seemed very concerned with my problem and wanting to remedy it quickly.

May 13, 2015

Dr. Dassel is exceptional

April 19, 2015

Dr Dassel never makes me feel rushed. He takes the time to answer all my questions and makes me feel like he really cares.

April 17, 2015

I feel the provider decided on a plan before I was ready for that decision. I would like to be able to discuss further with him the test findings before determining whether surgery is necessary.

April 01, 2015

Great experience.

March 18, 2015

there is no better provider out there! Dr. Dassel is very intelligent and understanding.

January 05, 2015

Dr. Dassel made me feel comfortable and made sure I was scheduled for a follow up appointment. He answered all of my questions and remembered that I had Hashimotos autoimmune disorder. That level of attention to detail reinforced my confidence in him as my doctor.

January 02, 2015

Great experience. Will readily recommend to family and friends.

December 13, 2014

October 10, 2014

Throughout my pregnancy and after, Dr. Dassel has been great. He takes the time to explain things not only for the questions I have but also things I don't know to ask about.

October 04, 2014

Dr.Dassle is great!!

October 03, 2014

I know Dr. Dassel is very busy, but he never rushes through my appointments. He takes time to talk with me and make sure everything is going well. He is very good at informing me of things that I might have questions about and always makes me feel very comfortable.

September 29, 2014

Dr. Dassel was amazing, he spent almost an hour with me going over treatment options. I feel completely confident in the decision for surgery and and thrilled I was referred to him.

September 19, 2014

I thought Dassal was very competent. I am interested in why's and the bodies exposures and nutrient status which I do not think he focuses on. So far, I totally trust him in his practical approach to isolating the problem. His attitude was very positive which is quite helpful in a somewhat scary scenario.

September 06, 2014

I am so happy with choosing Dr. Mark Dassel as my new gynecologist. He has such a down to earth bedside manner that it put me at ease. I would highly recommend him not only for his expertise, but for his genuine concern for me as his patient. The daybreak hospital is beautiful and the staff is great as well.

August 10, 2014

Dr. Dassel was excellent. Its always uncomfortable having to bare all in these examinations but he was very gentle and made me feel much more at ease. He seemed to have a genuine concern for the problems I explained to him and brought up some new information no other doctor has ever even mentioned. He spent a lot of time with me (as did the nurse) getting to know exactly what is going on with my body. I just wish I could have seen him sooner!

August 09, 2014

Dr. Dassel is a wonderful doctor, professional, friendly, helpful and very knowledgeable about my condition. I have worked with 10 doctors, including Dr. Dassel, in trying to handle this condition. Dr. Dassel is the first doctor to be thoroughly knowledgeable about this condition and the different options and including me in on a discussion on how to deal with it. He is full of positive energy and a desire to help me. Dr. Summers could learn a lot by watching Dr. Dassel on how to work WITH patients.

August 07, 2014

dr. Dassel is friendly and knowledgeable. He went out if his way to answer questions that I had and treated us wonderfully except for the wait.

July 26, 2014

I feel comfortable with Dr. Dassel, and his confidence and knowledge makes me feel at ease.

July 25, 2014

i cant say ANYTHING negative about my experience.

July 18, 2014

I have nothing but good things to say about Dr. Dassel. Initially I was a little nervous to see a male provider but I left feeling lucky that he was the one with an opening. He was very kind, listened well, and took time to make sure I was well informed about the minor procedure he was performing for me.

July 17, 2014

this was my first time seeing Dr Dassel, and he was so friendly and thorough.

July 16, 2014

I love Dr. Dassel. I appreciate that he takes the time to ensure I understand what is going on and what to expect. He has never been condescending, even when asked (what I perceive to be) stupid questions.

July 15, 2014

Dr. Dassel was just wonderful! He could teach other doctors in this office some valuable lessons in listening and caring about helping in the capacity they are being paid to do. Great experience!!

June 27, 2014

Dr Dassel drew an explanation & answered all my questions. Sooo good.

June 26, 2014

Coming to this appointment, I was frustrated about an accidental cut that happened during a surgery that I did not expect, which has lengthened my recovery time. Dr. Dassel was very apologetic of the accident and explained what happened, which I hadn't heard post-surgery. While I'm still annoyed that it happened at all, I appreciate his acknowledgment and apology for the situation.

June 25, 2014


June 24, 2014

nice friendly and quick addressed all my questions and concerns

June 20, 2014

I appreciate the care and time Dr. Dassel takes when I see him. I don't mind waiting a little extra time, because I know he is taking the time necessary with his patients. I appreciate how thoroughly he answered all of my questions.

June 10, 2014

Dr. Dassel is amazing! He is so nice and caring. He really explains everything that is going on and takes the time to go over any concerns or questions. Even though I was the last patient of the day and it was after 5pm, he never acted rushed; he made sure all of my questions were answered and that I understood next steps.

June 10, 2014

Dr. Dassel made my experience a very positive one. He is knowledgeable, personable, and efficient. I am now relaxed and confident about my treatment. I was one of his first patients of the day, but at the end of the day as we were both leaving the facility at the same time, he remembered my name and was still very friendly and pleasant.

June 09, 2014

Dr. Dassel's care was exceptional! He explained the procedure in depth while demonstrating sincere care and compassion throughout the entire visit. Huntsman Cancer Clinic is fortunate to have such an intelligent and personable doctor as this young man.

May 07, 2014

I've already recommended him and im so pleased I found a dr who took my problem seriously and hopefully the solution we found is going to solve everything!

April 21, 2014

I have seen Dr. Dassle several times, and with each visit, I feel he forgets more and more about me, my history, and treatment options. It is very frustrating to have to go over everything, especially since I see him approximately every 2 months.

April 17, 2014

Hes wonderful couldn't ask for better. Lots going on and he really goes above and beyond to make sure im getting better.

April 11, 2014

February 22, 2014

February 21, 2014

I've never had a better experience with a physician as I've had with Mark Dassel and I doubt I ever will. He is patient, empathetic, and very competent. I would recommend him to anyone.

January 31, 2014

I was really happy with Dr. Dassel, he spent a long time with me going over my concerns. I didn't feel rushed, or like my concerns weren't valid. Dr. Dassel and the PA were also very friendly, and my my visit very comfortable.

January 30, 2014

I am very happy to have Dr. Dassel as my Dr. A potential problem has been thoroughly checked out and follow up care well defined. He has listened to my concerns and taken great care of me.

January 09, 2014


December 21, 2013

I initially felt like he was listening to my symptoms and wanted to help me. He referred me to a website that discussed what he thought I had. I emailed him saying that my symptoms do not match what the website symptoms are and I would like additional testing and I was dismissed and they suggested I see a different doctor.

I had an excellent experience on my first visit with Dr. Mark Dassel. His bedside manners were extraordinary, caring polite & friendly yet very knowledgeable and confident. I had never seen him before but he made me feel at ease, he asked the appropriate questions and included me in the plan of care. I am very pleased having him as my GYN doctor and I would definitely recommend him.

amazing as always and incredibly thorough and willing to listen to my concerns and thoughts and make sure we werent missing some vital detail and just jumping into surgery or a procedure.

December 04, 2013

Dr. Dassel was very friendly and knowlegeable. He explained my condition very well, and made sure I understood the treatment plan and my options.

Dr. Dassel is the best physician I've ever come across. He is thorough, genuine, and patient. He never seems in a rush and is always willing to answer all of my questions.

November 25, 2013

The Dr was great, did not make me feel rushed and spent a large amount of time discussing options with me for something that is very complicated. He considered all options and was open to discussing the pros and cons of each. Worked on making an overall plan for treatment, compared to most surgeons who are interested in the surgery part and forget you have a life typically afterwards.

he was very busy and very behind, parts did seem a bit rushed, it kinda felt like he had come to a conclusion without discussing whether my exam had ruled things out or not, it was just odd to go from this list of things it could be down to one with two options one conservative one not. i just wonder how we got where we did, how other things got ruled out but all in all in the end i kind of understood and his diagnosis did make sense just a more rushed appnt so maybe thats the deal, not dissatisfied by any means just a different experience this time.

Really good experience with Dr. D., he will be my 4th OBGYN in 2 years and I'm really hoping he will be at the clinic for quite a while so I can continue care with him.

October 21, 2013

Immeadiately after leaving the room for me to change I could hear the doctor and nurse laughing and joking loudly.

October 21, 2013

Dr. Dassel spent a good deal of time with me. He answered my questions well and even told me where he obtained the information. Medication information provided by Dr. D. didn't match the information given in the warning labels of the meds. Which is my I rated this fair. Instructions for follow-up were actually irrelevant as surgery was the next day.

October 15, 2013

after all the waiting i did to finally see such a great dr, he was well worth the wait. i finally feel my problem will be solved and i finally have an ob i can trust!! he was so thorough espescially when i was expecting an excuse to be used why he couldnt be as others have done in the past. he really helped me understand in detail what could be going on, gave me all options and i left feeling like he did more to help me and really took my problem seriously than i have ever experienced in all ob offices put together. im hoping follow through will be as impressive but that part is kind of out of his hands but im confident hes on top of it
