Patient Comments

*Cassie is a wonderful provider - takes the time to really go over your childs well being & answer any concerns. I imagine though this is what may cause her to run behind possibly? We normally see *Dr. Diamond who is great & very quick & to the point. But I do appreciate the thoroughness of *Dr. Wagner.

Nurse practitioner did an amazing job at listening and allowing my daughter to speak about her concerns. She was also very supportive of treatment we chose.

I can not say enough positive things about Dr. Cassie!!! With my son having ASD, doctor appts are historically very difficult for him. Cassie was very willing to meet him on his level and when he was ready! And this Mom appreciates that more than anything!!!!

Dr. Cassie was amazing. She was very caring and helped step by step to go through her concerns with my son's symptoms. She explained everything in detail. She truly cares about her patients like they are her own kids. She followed up with me that night on my son's blood work and explained in detail for 20 minutes. This was by far the best service I have ever had with Iowa Specialty. Dr. Caleb & Dr. Cassie are amazing providers to have at your clinic, and I would recommend everyone to them.

We love Cassie! She sees us every time an illness pops up, and is always so thorough and so concerned. She's so amazing with Arthur and he really loves everyone at the clinic.

My child is normally nervous going to the clinic, and meeting Cassie changed that! They instantly loved her! Cassie was thorough for the physical and brought up important safety topics that made me realize I needed to have with my all children again. Cassie is awesome!

My kids love their NP.

*Dr. Wagner has the best bedside manner I've ever come across. So often doctors seem to rush through their day on some type of coasting made - but *Cassie was very attentive and personable.
