the doctor spent a lot of time with me

January 27, 2017

Great experience!

December 19, 2016

Dr. Callis is considerate about your privacy, keeping the patient covered, moving quickly, and addresses sensitive issues with care. She is such a professional and I trust her knowledge and skills in providing for my health.

December 13, 2016

A very caring, though and courteous professional .

December 03, 2016

this doctor is the best..... Never let her go

December 02, 2016

Great experience

November 30, 2016

Best doctor I've ever had. I would have had saved thousands of dollars and time had I known Dr. Kristina Callis-Duffin years ago. I've been seen by many Dermatologists in the past who did not help me adequately including one from the University of Utah.

November 09, 2016

I have been pleased and impressed with my care in this clinic

October 26, 2016

Dr. Callis is fantastic! Figured out an unusual etiology for my common problem and treatment is working.

September 23, 2016

Dr. Callis is great, and very good about sharing her knowledge and experience to treat and maintain my psoriasis. She was also very helpful about other skin issues.

September 17, 2016

Great communication from my Doctor. She was very professional while making me it feel personal .

September 10, 2016

Bit more rushed than normal.

September 07, 2016

Love Callis, she is so good

August 26, 2016

I did give Dr. Callis' name to another person.

August 21, 2016

Dr. Callis is always very informative when giving me information. I have always felt like she gives me the choice in what my plan of care is going to be, whether it has to do with medications or future appointments. She answers all of my questions without hesitation

July 27, 2016

I appreciate Dr. Callis' time and attention. I also appreciate that some of my questions relate to anti-aging practices and products and even though my appointment was focused on a skin cancer check, Dr. Callis takes my questions seriously and provided information I found helpful. Dr. Callis' communication is clear and she is professional and discrete, providing privacy and discretion during my examinations. She is personable and knowledgeable, helping me to understand follow-up and possible concerns about my skin.

June 27, 2016

I really mean all of the above questions above described were excellent service Very happy with my pick of MD

June 22, 2016

Exceptional knowledge and abilities

June 20, 2016

Doctor is one of the better doctors I have had the pleasure of meeting.

June 03, 2016

always good

May 10, 2016

After the appointment I thought of questions that I should have asked and wished that the Dr had covered those details, but that is more my fault than the doctor's.

April 16, 2016

I just love Dr Callis!

April 07, 2016

It was a relief to talk with Dr. Callas-Duffin. She listened to my frustrations and discussed options and treatments available. I felt very confident in her recommendations.

April 01, 2016

I appreciated Dr Callis taking time to discuss options and really explain the condition. She allowed me to take part in my care. She is great!

February 26, 2016

I really appreciated Dr. Callis and her willingness to see me. I have psoriatic arthritis and was seeing her mainly based on problems with my joints more than my skin. When explaining how medication worked I feel like she went way too in depth and used a lot of medical jargon that went way over my head, but I understood enough just because of the research I had done about my illness and medications prior to the visit. I appreciated that she was stern, but she definitely came off a little rude, as if my concerns for the side effects of the medications she was recommending to me weren't valid or something. If I brought up a side effect that I was worried about I feel like I was offending her somehow because she seemed to get defensive in the way she countered my concern. My rheumatologist I had before (left the practice I was at before) was very wish washy so even though I felt these negative things from Dr. Callis, it was refreshing to have a doctor who gave me direction and was confident about what she was prescribing. In the end I decided to take the medicine she suggested even with my fears of the side effects. So in that sense, she was effective. I look forward to our follow up visit and wonder if I just caught her on a bad day or something, I think she may have been frustrated at the fact that I was mainly looking for advise about my arthritis and not skin. I think I'll have a better gauge of how I feel about her after my next visit though. All in all, I am grateful

January 13, 2016

Descriptions in My Chart with regards to medical terms were useless. Didn't understand a word.

January 11, 2016

Experienced; professional; very knowledgeable

November 26, 2015

Very professional

November 15, 2015

Dr Callis-Duffen is top of her field. most doctors couldn't even diagnose the problem and she has got it in control for me

November 09, 2015

Dr. Callis is exceptional as a care provider. She not only addressed the follow up, issues and concerns that I had, but called me later because my blood pressure was high. When had checked my history and knew the change. When I was selecting the plan at work I made sure she was on the plan. One of the best doctors I have ever seen in any specialty.

September 29, 2015

Have used Dr. Callis as my dermatologist for several years and am very pleased with her. biggest problem is scheduling an appointment with her since they are usually several weeks out.

September 07, 2015

It was a very good experience.

August 31, 2015

Dr. Kallis had an assistant. I believe she was documenting the session. She was positioned in front of me. Although I had a gown, I was effectively naked, and directly in the line of sight of the assistant. I felt awkward and uncomfortable. If the presence of such a person is necessary, perhaps she could be positioned elsewhere. Ideally, however, the doctor could document the session herself.

August 30, 2015

exceptional care

August 11, 2015

Dr Callis is a wonderful doctor. She listens to my concerns and takes the time to help me understand my options. I value her opinion on my health issues and diagnosis of any problems.

June 25, 2015

Kristina always goes the extra mile to provide the very best care for me

May 08, 2015

I find that Dr. Callis Duffin is an excellent doctor.

May 02, 2015

Excellent care.

April 18, 2015

Dr. Callis-Duffin was able to quickly identify a possible problem I was not even aware of.

April 05, 2015

I have seen Dr. Callus about 3 or 4 times. She is the only mole doctor I have ever seen and will continue to do so.

March 23, 2015

Dr. Callis-Duffin was able to tell me a probable story about what was going on with me. She took into consideration my history, my current symptoms, test results and was able to give me a probable diagnosis. I was amazed and relieved to have everything explained.

March 18, 2015

Dr. Kristina is my favorite doctor. She always goes above and beyond to provide the best level of care. I have referred many friends to her, and put my full trust in that she provides the best care available.

February 28, 2015

This is my first visit to the UofU dermatology clinic in very long time. I am very impressed with Dr callis-duffin. I feel with her knowledge and concern we can make my life much better.thank you DR.AND ALL YOUR STAFF. Thank you very much.

February 23, 2015

I would consider this a very good experience. I have the highest confidence and respect for my Doctor, and the ease in which she can make me feel comfortable during our visit.

February 16, 2015

I love my doctor and her office

January 25, 2015

Everything was explained in terms I could understand and my questions and concerned were answered. I have recommended my daughter to this doctor.

January 12, 2015

Doctor was very through and is a pleasure to work with.

December 27, 2014

We have been with this care provider for several years. She answers all of our questions and includes my wife in our discussions

November 29, 2014

Because of the excellent service I receive, I have already recommended people to this Dermatology office.

October 22, 2014

Every answer here would be very good 5. The survey is very long and when you ask times spent, I do not watch my clock. Just know that in every way Dr. Callis is a #5

October 17, 2014

Dr. Callis explains the procedure and plan well so its easy to understand.

October 10, 2014

Dr. Callis-Duffin is a phenomenal physician! She is very friendly, professional, knowledgeable, and thorough. The fact that she engages in research and is a member of the University of Utah faculty is indicative of her commitment to advances in dermatologic treatment. I appreciate that Dr. Callis-Duffin is always willing to provide advice and that she is personable in her approach to managing the patient-physician relationship. Excellent physician!

September 04, 2014

All the staff are absolutely outstanding

July 14, 2014

I REALLY like how Dr. Duffin uses the real words for conditions, but I am a visual person needing things to be written down for me to remember them and even though she said the word several times and she even googled it for me, I have already forgotten what it's called. I do know where I might be able to find it online given that I have psoriasis. She is great at explaining in laypeople terms what a technical term means and what is going on with a certain physical symptom or condition you have.

June 23, 2014

Dr. Callis is very knowledgeable and I appreciated her willingness to take on my case.

June 16, 2014

Dr. Kallis-Duffin is easly the best dermatologist I have ever had.

June 16, 2014

Dr. Callis seemed rushed at the appointment. I would have liked to have spent more time making a decision about a potential treatment option.

May 27, 2014

Since my insurance did not cover the visit, I am very grateful with the flexibility provided to address my problem.

May 24, 2014

I have no complaints!!!!

April 24, 2014

Dr. Callis-Duffin and PA Jessica took the necessary time to explain the treatment and care of biopsy site to me.

March 31, 2014

I feel she is an old friend who has never been a better doctor.

March 21, 2014

Dr. Callis was, as always, wonderful. The fellow, Dena, was also very good. The PA was new and very friendly, but was clearly on a learning curve in using the computer system and entering prescriptions.

March 21, 2014

she phoned me about biopsy results promptly. she put me at ease about my problem and gave me instructions for further care that is needed.

March 03, 2014

I, again, was treated well and had a good experience. In the past, many years ago, the staff was not the caring people I now associate with the U of U Dermatology.

February 14, 2014

Dr Callis is AWESOME! She is so easy to talk to and I never feel rushed. She always takes the time to answer my questions.

February 01, 2014

I Love my doc

January 31, 2014

Dr. Callis-Duffin has been very very good with my problem. She couldn't have shown more concern. I call her my angel!!!!!!!

January 27, 2014

Dr. Callis has helped me tremendously with her knowledge and caring. She helped me clear up a very visible skin problem on my eyes that was painful and embarassing. This also led to other improvements with my skin. I appreciate her so much! She is a one of a kind, wonderful doctor.

January 27, 2014

Dr. Callis has always shown great care and professionalism in her work and is very competent.

January 17, 2014

I really appreciate how well she explains my options and helps me choose what is best for me.

December 04, 2013

great experience every time I go

November 25, 2013

dr. callus is the best

November 20, 2013


November 08, 2013

I have recommended her and will continue to do so with confidence.

October 11, 2013

This was a follow-up appointment and the doctor explained everything new very clearly.

August 19, 2013

Dr. Callis is by far the best dermatologist I have ever seen, (I should know, I have been seeing dermatologists regularly for over thirty years.)

August 14, 2013

Dr. is very good at listening to your concerns and addressing them with you.

August 13, 2013

great resident, attending and assistant

July 10, 2013

excellent physician in all respects

July 08, 2013

I really liked Dr. Callis and Jessica so called bed side manner. :)

July 03, 2013

Dr. Callis-Duffin is very friendly and answered the questions I asked clearly.

July 02, 2013

Dr. Kallis is amazing! She is always fun, professional, and it's quite obvious that she cares for the education of others. Despite the circus atmosphere of each exam having at least four people in the room (standard for a teaching hospital, so completely acceptable), every visit to Dermatology at University Hospital is superb. I think it's so nice to see Dr. Kallis work with her students to ensure that they understand what is happening in an effort to develop healthcare leaders and practitioners of the future. Dr. Kallis is wonderful!

May 24, 2013

Dr. Callis earned a 6 in my opinion, but I don't have that option on the survey

May 13, 2013

excellent patient experience

May 10, 2013

Dr. Callis is the best. Practical, smart, friendly, accomodating, good sense of humor

May 03, 2013

Dr.Callis and the Physican that was following her did an excellent job at making me feel treated with dignity and respect.Thank-you so very much you made my experience wonderful.

April 12, 2013

I know that Dr. Callis and her staff will be able to help me with my condition and get it resolved.

March 16, 2013

She is a very informed Dr. and always a pleasure to consult with.

March 12, 2013

I have already referred Dr. Callis a couple times.

March 06, 2013

The medical terms for my possible condition were complex & difficult for me to remember without seeing them written down. Not sure how to fix this.

March 04, 2013

Caretaker scheduled me on a day when she does not normally see patients because she wanted me to begin treatment for psoriasis ASAP.

November 15, 2012

Dr. was very nice but due to having the wrong chart the apt. was frusterating. She would ask about my history and I had to explain the failure of the MA to listen when I said I have never been to this clinic before!!

November 12, 2012

I have recommended her in the past and will continue to recommend her in the future.

October 27, 2012

I found Dr. Callis very friendly, informative, clear in her explanations and recommendations of the next steps that are needed.

September 21, 2012

I trust Dr. Callis-Duffin immensely. She is knowledgeable, professional, and yet approachable. I would recommend her to others.

September 10, 2012

Thorough, professional, and caring; Dr. Callis Duffin is great!

July 16, 2012

I could not have been treated any better. Thank you!

July 12, 2012

Dr Callus is a qualified physician and genuinely kind.

June 27, 2012

Care has been excellent. I would like my son to see Dr Callis if she is taking new patients.

May 16, 2012

I would and do recommend this doctor. She is the best.

April 05, 2012

She is very nice and seemed concerned about me.

April 05, 2012

Dr. Callis was very nice and explained everything.

March 27, 2012

Dr Callis does an outstanding job for me at my visits.

March 23, 2012

The fact that I had an afternoon appointment (2 P.M.) was, I'm sure, the reason for the long wait time. Things always get backed up in the afternoon...

March 23, 2012

Exceptional experience and the highest level of confidence in Dr. Callis

March 13, 2012

Best visit ever!

March 06, 2012

If only I could take Dr. Duffen with me every day. She is great. The only one out of six different doctors that has cleared me up and made me feel better about my psoriasis

March 06, 2012

I have seen alot of doctors for my skin. And finally she has been able to clear it up. I'am very happy with her.

February 14, 2012

The Doctor and her Assistant were both excellent!!

February 04, 2012

the nursing staff on saturdays is verry friendly and take the time to talk to you and listten to you

January 31, 2012

Excellent doctor.

January 17, 2012

This appointment was very good. My last visit was way too rushed and there was not enough time for me to ask questions. The Doctor was way too busy.

January 05, 2012

Very confident.
