Review of Dr. Prezas

- in San Antonio, Texas |

Don't know why others here scored Dr. Prezas & staff so low, but, we all have our own experiences and relate them differently. For us, Dr. Prezas has been a wonderful, caring, knowledgeable doctor. His staff has always been patient, helpful, kind, efficient. I feel a sense of personalized care here; like they are genuinely concerned and they show this in their actions. Dr. Prezas & staff (specifically Ashley Yarborough) have gone above and beyond in our mom's care.
