I did not see much of curiosity and thoughtful conversation with the doctor about my child's problem.

Listen and actually make a positive change to the plan to keep her numbers better at school. Her numbers are terrible at school and dr. Dyess did nothing to fix it. They wasted my time having me sit there for over 2 hours & I had to come back for blood work

We had a great visit with Dr. Dyess. He is incredibly knowledgeable and takes his time to explain our son's treatment plan in great detail. We know our son is getting the best care!

All was good we were treated very well

Everyone was great. Our nurse was kind and thorough. Dr Dyess was thorough and explained things well and treated my child kindly. I also appreciate not having to fill out multiple online questionnaires before the appointment. I do think prisma needs to change their text message reminders to refer to physicians by their titles and not just "your appointment with Ryan Dyess...". Physicians should be referred to as Dr in all communications regarding our appointments.

Nothing different. The Dr is always patient and caring to my children. The nurses are always polite and professional. They have a very pleasant office and most importantly they are kind to my children and make them feel safe.
