This was my cardiologist 15 years ago, and I was so happy to be able to see him again through my insurance. I truly feel like I’m in good hands. He takes the time to listen, shows genuine care, and explains everything in a way that’s easy to understand.
The office staff is also wonderful—everyone is caring, friendly, and helpful. I go to the DeLand office, and my experience has always been positive.
If you’re looking for a cardiologist who will listen to your concerns, understand how you’re feeling, and clearly explain your condition and treatment options, I highly recommend this practice. They are among the best.
