We haven't always had the best experiences with other specialist providers. Dr. Barger and Nurse Jeannie have renewed our faith. Always a pleasant visit. Everything is explained so we can understand. If we have more questions, calls are returned when we leave a message. They make sure all questions are answered in a way that is understandable for us as parents and for our kiddo since he is receiving the treatments.

Dr. Katie makes my daughter feel great every time she goes and visits her, although her condition requires her to take a pill every day and that makes her feel a little upset. I noticed that when she visits Katie, she feels a lot better and feels a little bit more normal when she explains to her everything. So we love Dr. Katie and we appreciate her so much and I'm so happy that my daughter has her as a doctor.

We really liked Dr Barger! She was knowledgeable, compassionate, and explained everything so well. She really listened to our concerns and was very validating. It seemed important to her to give us all the information available so that we could make the correct choice for our family, which we appreciated immensely.

Dr. Barger is the best!

Dr Barger and Vesna were great during our first visit. Wish we switched to PCH Endocrinology sooner!!

Dr. Barger is an amazing doctor. We are so fortunate to have her care for our daughter's conditions.

Always great!

Dr Barger is an Angel. I don't know how many children are in her care, but she makes me feel like she really understands what it is like to try to get your child to accept a diagnosis they didn't cause or deserve. She has a demeanor that gets through gently to my teenager who is very angry and sad.

Dr. Barger and Nurse Jeanne always go above and beyond to give me the time to explain and understand everything related to my son's health. They also pleasantly help me/my son with necessary paperwork to fulfill his extracurricular activities.

Great visit! We really appreciate all Dr. Barger does for her patients and the time she takes to ensure all our questions and concerns are addressed.

The Doctor was very prepared for our appointment, excellent listener and bedside manner, clearly explained next steps and left us feeling like she cared and is a true partner in the care of our child.

Dr. Bargerand the nursing staff are always so pleasant, kind and caring. I'm not looking forward to my daughter ages out of Phoenix Children's hospital. They provide the best care.

Having never been seen for this type of diagnosis, I was very pleased with the steps taken to ensure our daughter was comfortable with what the specialist was doing and saying. She spoke with both our daughter and to us in a very clear, direct manner and answered all the questions we had.

We are so happy to have Dr. Barger as our daughter's physician! She has a wonderful bedside manner and made my daughter feel comfortable quickly. She is knowledgeable and easy to talk to. I highly recommend her.

Thank you thank you! Often times specialists are rushed and don't tend listen to concerns. This was not the case with Dr. Barger. She made sure our concerns were addressed. And our questions were answered. She explained everything and did her best to ease the discomfort. So thankful to have her on our team of specialists.

She's the best Doctor for my daughter!.

Loved Dr Barger! So happy to have a kind, u restating doctor who explains things well and listens to us! She didn't rush us, just really loved her.

Doctor was very nice and communicated very well with my daughter.

We were very pleased with our last visit. Our nurses and Dr we very good to explain our bloodwork results and what each one means. We appreciate that everyone took their time and made us feel very comfortable discussing our concerns.
