5. Off the charts. Cassie is THE BEST! Both my boys love her, even though toddler is shy & the other one is 2 mo. She truly cares for our kids like they're family.

*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.

Cassie is very thorough and great with kids. Relates to them. She wanted to see my son perform some strength exercises like walking like a duck so she got right down and walked like a duck so she could mimic her. Impressive!
