There was a resident shadowing the doctor, and he wanted to show her something in my son's nose, but she couldn't see it and my son was clearly uncomfortable with the magnifying light thing in his nose. it wouldn't have been as bad if either one would have talked to him, made sure he was okay, or reassured that they would be done soon. both acted like he was just something to be studied. His only comment when we left was that he was scared when the thing was in his nose.

We feel blessed to have Dr.Grimmer as our doctor. He has always gone above and beyond what most doctors do. As a patent I feel so confident in him and his staff. He tells you how it is and what options you have . I have told him that he can't retire because I don't know if I could trust another doctor as much as I trust him.

We have seen many doctors at PCMC in different areas and Dr. Grimmer is truly one of the VERY best! We will probably never see him again but would recommend him to anyone needing an ENT.

Dr. Grimmer is amazing. We have LOVED working with him. As a surgeon he is EXTREMELY competent and as someone that cares about our daughter, we really couldn't ask for anything more! He operated on our daughter about 5 minutes after we met him - and even if I had known the guy for 20 years, I wouldn't have felt any better about his skill level. He made us feel very confident from the beginning and he was great to pick up our bizarre epulis case and run with it. THANKS!!!

The doctor did not know what was wrong with my son, took some pictures to send to colleagues and did not even venture a guess as to the problem. I asked if it could be cancer but the doctor said no, but did not elaborate. I left feeling like we were back to square one and Ialso had to ask about pain management for my son, nothing was offered

Dr. Grimmer is the best. He not only addressed the issue we had been referred for, but he also listened to me when I wanted to talk about other relevant issues. We left the appointment with a diagnosis that needs attention and he was able to explain things well and put me at ease. We've been dealing with issues for months and he is the first provider that has listened and immediately knew what to look for. Thank you Dr. Grimmer!

Dr Grimmer is amazing. I really appreciate how professional and kind he is. My daughter has a genetic syndrome that can cause hearing issues so we meet with Dr. Grimmer every so often for tubes (which help resolve the hearing and ear infection issues). Dr Grimmer is a brilliant doctor and he really cares about his patients. My daughter says Dr. Grimmer is one of her favorite doctors. He always takes time to speak with her and ask her how she is feeling.

Dr. Grimmer was very good. We felt very comfortable with him and his information. He wasn't in a rush and took the time to answer all of our questions. He was also great with our son.

When my son was readmitted into the hospital, I felt that Dr. Grimmer was the only person besides myself that knew and cared about my sons special needs. He came to the rescue in a very difficult situation and I will always trust his judgment.

I appreciated Dr. Grimmer's explanation of risks/benefits to bronchoscopy and his clear recommendations on when to pursue this procedure. I also appreciated his willingness to explain his thought process in medical terms (once I explained that I am also a medical professional). He spent plenty of time discussing the issue and addressing my questions. I left feeling reassured and confident in his recommendations.

For how hard we had to work to get to our appointment (we came from out of town), and to schedule all aspects of the appointment because we had to include a sleep study at the same time, I wish we would have been told that there was a possibility that my son wouldn't be scoped. There was a lot of stress getting ready for the appointment and I didn't leave with full peace of mind that we did everything we needed to to make sure he was okay. I'm okay that the procedure wasn't done if it wasn't necessary but it would have been nice to know that there was a possibility that it wasn't going to be done because most of our stress and planning for the whole day had been centered on getting it done... If that makes sense.
UofU Patient
November 19, 2012
Dr. Grimmer took his time with us. He didn't talk fast or treat us like a # like other doctor's often do. He was very patient and made sure all my questions were answered before I left. He even let me look into my baby's ear so I could see what her tubes looked like. When the exam was over, instead of quickly leaving the room and going on to the next patient he waited for me to buckle my baby into the stroller and he opened two different doors for me. I was really impressed with his kindness and caring! I will be recommending him to all my friends for sure!

Dr Grimmer spent a lot of time with us and never acted rushed or seemed preoccupied. He acted like Chloe was his most important patient, answered all our questions, and put her fears to rest. He is a wonderful dr with a fabulous bedside manner, especially

This was a decent experience. I would have liked a little more discussion about my child's health, specifically options (pros and cons of surgery), where I could address additional concerns and questions after reading literature given me. I left not really sure what I should do next.
UofU Patient
April 12, 2012
He didn't seem to care about my concerns. Made me feel like I shouldn't be there.

I wish we would have had time to ask more questions before our doctor left to talk with his next appointment.

Dr. Grimmer seemed uninterested in the situation. I realize he didn't have a lot to do with my child's sinus infection, but it is his specialty and we were looking to him for validation (or not) of our efforts to help our son.

There was only one nurse that was a little up tight. She was a older lady with long blonde hair. Maybe we thought this because the others were outstanding! There was a tall skinny gentleman, I think his name was Ken, he was amazing! He really conected and explained things to my daughter without freaking her out!
