Dr Grimmer is the most patient doctor I've ever met with. He spent time going over options with us and never made us feel like he was in a hurry to get to his next patient.

I wish more detail had been given to us regarding the terms associated with PTEN.. hamartoma, the skin abnormalities that are associated with it etc. I stated in the meeting that we had never received any genetic counseling, etc. and left feeling like I knew about as much going out as I did going in. The genetic terminology was hard to understand, however was appreciative of the doctor offering to send me the clinic notes on the visit for me to have and re read..

we were referred to this provider for a specific reason and it was very clear he had not read the referral for the reason my daughter was being seen and didn't really understand why we were there.

my husband brought my son and I couldn't leave work, the dr was more than willing to discuss via FaceTime all of my concerns. I was able to feel as if I was there and appreciated his understanding for me not being there.

March 14, 2018
Dr. Grimmer is amazing! Every time we have seen him he always takes the time to explain things and ask my son if he has any questions. His bed side manner is the best. We have referred everyone we know that needs any ENT procedures to Dr. Grimmer, there isn't anyone I would trust more. Thank you for your excellent care and always going above and beyond to address any questions or concerns.

I really appreciate Dr. Grimmer. He is helpful, patient, & SOOOO great with a nervous child. He was able to gain _____ trust which is so difficult to do when he is scared. Our appointment was at the end of the day and at the end of the week and he was absolutely stellar with _____ as well as explaining to me his thoughts on _____ condition. I feel confident what to watch for and whether or not we'll need a 3rd set of tubes in his future.

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.
UofU Patient

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.
UofU Patient
October 14, 2013
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.
UofU Patient
September 10, 2013
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.

felt like our child's issue was treated lightly by him and that we were wasting his time by even being there. he did nothing to help us

Dr. Grimmer is great at explaining my daughter's medical needs, her options, and acts like we are the only patient he has to take care of that day.

December 27, 2012
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!

UofU Patient
April 25, 2012
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.
UofU Patient
April 11, 2012
I wish we would have had time to ask more questions before our doctor left to talk with his next appointment.
UofU Patient
April 04, 2012
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.
UofU Patient
February 29, 2012
Dr. Grimmer has been very good to listen to us and let us know what our beset course of action would be.

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!
