December 17, 2016

we were only with the dr for 5 minutes

August 30, 2016

he seemed like he was in a hurry and didn't have much time

July 26, 2016

Very efficient and understanding, it surprised me how well my son listened to his instructions

July 24, 2015

Dr. Grimmer is extremely knowledgeable and ensures that my family is at ease and comfortable with our next steps.

March 09, 2015

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.

January 25, 2015

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!!!

November 22, 2014

I will recommend this doctor to a friend of mine. He was great!

November 22, 2014

Great experience.

November 08, 2014

Great! My daughter and I felt very comfortable and listened to.

September 19, 2014

Doctor and staff are amazing very knowledgeable. Took the the time to listen to me and and actually consider my observations and comments during the diagnosis.

August 11, 2014


June 25, 2014

very nice and knowledgable doctor

May 07, 2014

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

April 26, 2014

Absolutely LOVE Dr. Grimmer. Always feel comfortable and informed after his visits.

April 15, 2014

Dr. Grimmer has been my doctor since I was 13 years old and has been very good to me and I appreciate all his hard work.

April 12, 2014

I especially appreciated that Dr. Grimmer appeared to have read my daughter's history and knew what was going on before he even walked in the room. He was very thorough and recommended additional procedures

April 11, 2014

very happy with Dr. Grimmer.. outstanding ENT:)

March 14, 2014

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!

February 23, 2014

We love Dr Grimmer

February 13, 2014

My son is Autistic and Dr Grimmer was great with him. He'd never seen him before, but he put my son at ease and he was able to do an exam...much better than usual with my son.

January 25, 2014

Dr. Grimer was great.

January 17, 2014

I feel like Dr. Grimmer really cares about my son and can remember past visits with him. I know he sees a lot of patients and probably looks at the chart before hand to jog his memory but I really appreciate it.

January 10, 2014

Dr. Grimmer is an amazing doctor.

December 11, 2013

Very efficient physician. Quick diagnosis, which I was grateful for.

November 29, 2013

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.

November 19, 2013

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.

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.

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.

May 16, 2013

Extremely happy with Dr. Grimmer. I am glad he will be performing surgery on our child.

April 29, 2013

Very nice. Understood our frustrations with previous providers not listening to us.

April 22, 2013

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

April 15, 2013

I would gladly recommend this clinic to anyone needing their help!

February 25, 2013

Felt like he really listened to me. Valued my opinion.

February 05, 2013

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.

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!

October 09, 2012

Awesome experience with Dr. Grimmer! He was there for the initial exam, surgery and follow-up it was nice to have the consistency and he was very calming and informative.

August 27, 2012

Dr Grimmer is great, I would refer anyone to him. It took very good care of my son and answered all of our questions

July 07, 2012

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

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.

April 12, 2012

He didn't seem to care about my concerns. Made me feel like I shouldn't be there.

April 11, 2012

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

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.

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.

February 15, 2012

Great clinic.

February 04, 2012

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!
