January 26, 2015

I am so grateful for the wonderful care I received from Dr. Dassel. The surgery went better than I had hoped for and I felt safe and well-provided for. Thank you!

January 26, 2015

I couldn't be happier with Dr. Dassel's care; he is an excellent doctor.

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

Dr. Dassel was one of the best doctors I have ever been to and will continue to see him as long as possible.

December 12, 2014

He listened, his bedside manor was impeccable and he's a sweetheart

December 09, 2014

Dr. Dassel was wonderful! He really helped me feel comfortable and explained everything very clearly.

November 13, 2014

He's very friendly and personable. He made me feel comfortable and was very responsive to my concerns and needs. He didn't seem rushed and provided me with autonomy in my care, so that I felt empowered.

November 11, 2014

Dr. Dassel is comforting and answered all of my questions. He really cares about supporting myself and my husband through this first pregnancy.

October 28, 2014

dr dassel was amazing

October 25, 2014

Dr. Dassel is so kind, friendly and most important very caring.

October 10, 2014

I have been very satisfied with my experience working with Dr. Dassel. I will (and have) recommend him to any and all my friends.

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. After disappointing experiences with other doctors, I'm very happy with him and wouldn't hesitate to recommended him to others.

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 22, 2014

Dr. Dassel was wonderful. He was patient, caring and genuinely concerned about all health issues. He took his time and was not rushed and answered all questions. He personally made a couple of follow up calls to me. He is very knowledgeable and I felt very confidently that I had excellent care.

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 18, 2014

love the staff total confidence in MD and staff

June 14, 2014

I am excited to have U care!

June 11, 2014

I came in concerned about a lump in my breast and received very prompt and attentive care. I felt all my questions were taken seriously and addressed appropriately and quickly.

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 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 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.

June 08, 2014

dr dassel is amazing in every way, from our first visit I felt confident in his care, he was caring, easy to understand an he made me feel safe. the best Dr I ever had, and I've had many .thank you

Dr. Dassel has been a wonderful doctor through out this pregnancy. He is has been great in listening and addressing my concerns.

May 13, 2014

Excellent clinic visit provided by Dr.Dassel who was very pleasant, time-efficient and answered all my questions. He is an excellent physician!

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

Great experience with Dr. Dassel. I felt listened to and appreciated his expertise and recommendations to help with my current medical needs.

March 28, 2014

Dr. Dassel was a very personable doctor. He was really understanding and took into account everything I said to him. I felt very comfortable with him.

March 24, 2014


March 13, 2014

Both my doctor (Doc. Dassel) and my nurse (whose name I unfortunately forgot) were very kind and seemed very knowledgable

February 22, 2014

Dr Dassel was awesome. I felt like I was taken care of by him and he really knew what he was talking about. I feel like he really wanted to understand what I was going through. He was really great. I'll recommend him to all my friends

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.

December 15, 2013

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.

December 12, 2013

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.

November 29, 2013

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.

November 11, 2013

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.

October 30, 2013

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
