April 10, 2025
Dr. Seyfert is a rockstar! He's incredibly easy to talk to, he listens to your concerns, and usually has one to a number of possible solutions for you to choose from depending on your situation. He also tells you what he'd do if he was in your situation and will pretty much order you whatever test you'd like, if appropriate and in reason. This is a major help when compared to other doctor's who will beat around a bush or make you come back repeatedly, paying multiple copays just to try and track down whatever you're experiencing. He also can recommend which specialist to seek out, based on your situation, as well if you have something going on beyond his specific expertise. I love him, my folks now love him, my wife and kid now love him. My daughter actually started crying when we told her we had to LEAVE Dr. Seyfert's office and she's only 2 and 1/2 years old.
