She also received a grant from the National Organization for Hearing Research (NOHR) in 2011 to study the genetic variation in the immune system to otitis media.

    Dr MacArthur seemed knowledgeable and willing to thoroughly answer our questions. The procedure went fine.

  • Dec 29, 2018

    Dr. Macarthur was amazing, She was super professional and she didn't make us come back for unneeded things. She saw what she needed and got my son's surgery scheduled right away and took it very seriously and it didn't make me feel like I was crazy.

    She was professional, informative and kind to my 6 year old.

    Very friendly, respected my concerns without making me feel crazy.

  • Nov 30, 2018

    She was informative, went into greater detail of risks and options. She personally followed up with us after surgery.

  • Nov 20, 2018

    Dr. MacArthur is always attentive to my concerns about my son's ears. She discusses his treatment rather than just telling me what she is going to do.

  • Nov 16, 2018

    She was kind and caring. She took plenty of time to make my child feel comfortable and answer my questions honestly.

  • Nov 15, 2018

    Yeah, we actually had Dr MacArthur for not only our 5 year old, but our 4 year old last year, who was 3 at the time and she was fantastic. We actually had the sane nurse, Janet, oh my Gosh, they're amazing, so quick so pain ... pain less for us anyway, not for the kids. Absolutely, we would recommend them Dr. MacArthur (inaudible).

  • Nov 13, 2018

    My daughters dr and all the nurses where so kind and explained everything to us in a way we could understand

  • Oct 06, 2018


  • Oct 05, 2018

    A trustworthy surgeon

  • Oct 01, 2018

    The physician was on time, listened to us and was great with my son.

  • Sep 28, 2018

    Dr. MacArthur was informative when relaying information about my son's procedure, answered the questions I had very nicely before and after his procedure. I had complete faith in her to take care of my son.

  • Sep 25, 2018

    She had a true desire to figure out what is going on with my son even if it didn't fall under her area of expertise.

  • Sep 18, 2018

    Efficient and kind. Good bedside manner

  • Sep 18, 2018

    We had great interactions with the staff and doctors that we worked with. I have, on several occasions, had canceled appointments, schedulers who were unsure of our circumstances, and not okay wait times. Yesterday, we were scheduled for an 8:15 check-in (that we were on time for despite getting lost) and she did not go back for surgery until 50 minutes after her operation was scheduled. She is 15 months old. No food. No water. I really am telling people it is better to use a hospital closer to their home that is more little people considerate.

  • Aug 29, 2018

    The provider was kind and informative.

  • Aug 18, 2018

    She was great!!!! Thank you!!

  • Aug 12, 2018

    Dr. McCrosser was very professional, very?worked very well with my 9 year old who has high anxiety and did a good job of separating comments for parents in front of a very high anxiety child. Explained well, it was very good bedside manner with my daughter, answered questions, so excellent care provider. Thank you.

  • Aug 06, 2018

    She is always patient with my girls and explains what and why she is doing something.

  • Jul 14, 2018

    She is very proactive to promote long term health.

  • May 10, 2018

    Dr. M also responded quickly to my follow up questions via my chart email.

  • Apr 28, 2018

    nothing but good experiences with dr MacArthur. we have recommended her to multiple other friends.

  • Apr 08, 2018

    we sincerely appreciate having a team of professionals surround us who are extremely courteous and compassionate in their care towards us. we always walk away thankful for this team.

  • Mar 10, 2018

    we love Dr. McAurther

  • Feb 20, 2018

    Excellent doctor who is very knowledgeable. Not the warmest doctor in terms of interactions with our child.

  • Feb 12, 2018

    We thought Dr. MacArthur was outstanding. One could be forgiven for thinking this procedure was straight-forward without too many potential 'wrinkles', but such was not the case. Dr. MacArthur came highly recommended by our CF team, and for good reason; her knowledge and expertise instilled us with the confidence and security in knowing she'd be performing this surgery on our son.

  • Jan 06, 2018

    I think she knew we had a routine case for surgery and also that she was running really far behind so we were rushed in and out.

  • Jan 04, 2018

    She knew we were nervous and anxious about our sons diagnosis and she made herself available to speak with us prior to this visit to ease our minds. She was extremely confident with the way she communicated which helped us significantly. We are grateful to have had her for [Name] care.

  • Dec 29, 2017

    provider did not introduce herself to my son. she looked at the problem, told us surgery was the only option, didn't ask if we had additional questions, and ended by stating her surgery scheduler would call us.

  • Dec 29, 2017

    we were referred for a lip tie correction and the doctor we saw was so sweet! She helped answer all my questions and even made sure my son was good to go before sending out the door. As a mom our most important thing is to make sure our children are in good trusting hands and i feel she lived up to that caring for my son. Thank you Carol!!!

  • Dec 20, 2017

    The information I was given said that we would receive a call from the Dr's schedulers about cost for the treatment my son needs but I never got a call?

  • Nov 30, 2017

    I can't say enough about how wonderful she was!!!

  • Oct 03, 2017

    she is a great doctor!

  • Sep 07, 2017

    She guessed my daughters diagnosis because she was not sure what the root of the problem was after her tests were performed.
